Sunrise Meditation

The most successful people in the world are known to have a morning ritual, one that consists of setting goals and aspirations for the day. Contemplative individuals such as nuns and monks from a variety of spiritual paths begin their days very early, greeting the first rays of sunlight with prayer and meditation.

Use this meditation as a starting point for building a habit of greeting your day with a calm and centered mind. As the sun rises the night sky gives way to light and a new day is present, at this time let go of any sense of failure or regret of past days and times gone by. Greet the new day with an open mind and heart, feel compassion towards yourself and others.

Revitalize Your Hair Naturally: The Ultimate Avocado Hair Mask R

Introduction

Are you tired of dull, lifeless hair? Look no further! Avocado is a powerhouse of nutrients that can transform your hair from drab to fab. In this article, we will explore the benefits of using an avocado hair mask, provide you with the ultimate recipe for stunning results, and share tips for incorporating this natural treatment into your hair care routine.

Understanding the Importance of Hair Care

Hair care is essential not just for aesthetics, but also for maintaining the health of your scalp and hair follicles. The condition of your hair can significantly affect your overall appearance and confidence. While many commercial products promise quick fixes, they often contain harsh chemicals that can do more harm than good. Natural remedies, like the avocado hair mask, offer a safer alternative packed with nutrients.

Benefits of Avocado for Hair

Avocado is rich in vitamins, minerals, and fatty acids that nourish and strengthen your hair. Here are some key benefits:

  • Moisturizing: Avocado is packed with healthy fats that deeply moisturize the hair, preventing dryness and breakage.
  • Rich in Nutrients: It contains vitamins E, D, and B6, which promote hair growth and improve overall health.
  • Scalp Health: The antioxidants in avocado help soothe the scalp and reduce inflammation, promoting a healthy environment for hair growth.
  • Shine and Luster: Regular use of avocado can enhance the natural shine of your hair, leaving it looking vibrant and healthy.
  • Reduces Frizz: Avocado oil helps to tame frizz and flyaways, making your hair more manageable.
  • Strengthens Hair: The amino acids in avocado help strengthen hair strands, reducing the likelihood of split ends.

The Ultimate Avocado Hair Mask Recipe

Now that you know the benefits, let’s dive into the ultimate avocado hair mask recipe that you can easily make at home!

Ingredients:

  • 1 ripe avocado
  • 2 tablespoons of olive oil

优化AI驱动的Java应用程序API管理策略

在本文中,探讨了如何将 OpenAI 的 ChatGPT API 与 Spring Boot 应用程序集成,并通过开源 API 网关 Apache APISIX 来管理 API。这种集成使得在 Spring Boot 应用程序中充分利用 ChatGPT 的强大功能成为可能,同时 APISIX 提供了一种健壮、可扩展且安全的 API 管理方式。

OpenAI ChatGPT API

OpenAI 的 ChatGPT API 是一个强大的工具,用于将 ChatGPT 模型的功能集成到应用程序或服务中。通过此 API,可以发送一系列消息,并通过 REST 接口接收 AI 模型生成的回复。API 提供了多种功能,包括在聊天机器人中生成文本回复、代码补全、生成图像或在对话界面中回答问题。在本教程中,将使用聊天完成 API 来生成对提示的响应(可以询问任何问题)。在开始之前,可以探索 API,以了解如何使用 API 密钥进行身份验证,以及 API 请求参数和响应的格式。

以下是一个对聊天完成 API 的 cURL 请求示例。在调用 API 时,请将 OPENAI_API_KEY 替换为自己的 API 密钥,并放置在 Authorization 头中。

curl https://api.openai.com/v1/chat/completions
-H "Content-Type: application/json"
-H "Authorization: Bearer $OPENAI_API_KEY"
-d '{
"model": "gpt-3.5-turbo",
"messages": [{"role": "user", "content": "What is Apache APISIX?"}]
}'

以下是一个示例 JSON 响应:

{
"id": "chatcmpl-7PtycrYOTJGv4jw8FQPD7LCCw0tOE",
"object": "chat.completion",
"created": 1686407730,
"model": "gpt-3.5-turbo-0301",
"usage": {
"prompt_tokens": 15,
"completion_tokens": 104,
"total_tokens": 119
},
"choices": [
{
"message": {
"role": "assistant",
"content": "Apache APISIX is a dynamic, real-time, high-performance API gateway designed to facilitate the management and routing of microservices and APIs. It provides features such as load balancing, rate limiting, authentication, authorization, and traffic control, all of which help to simplify the management of microservices and APIs. Apache APISIX is built on top of the Nginx server and can support high levels of traffic with low latency and high availability. It is open source and released under the Apache 2.0 license."
},
"finish_reason": "stop",
"index": 0
}
]
}

项目代码示例

本教程分为两部分。第一部分讲解如何设置 Spring Boot 应用程序,并创建一个新的 API 端点,该端点能够通过编程方式处理对 ChatGPT API 的调用。第二部分则介绍如何利用 APISIX 的安全性、流量控制等功能来管理 Spring Boot API。本教程的完整代码示例可以在名为 apisix-java-chatgpt-openaiapi 的 GitHub 仓库中找到。

先决条件

在开始之前,请确保具备以下条件:

  • 创建 OpenAI API 密钥:要访问 OpenAI API,需要创建一个 API 密钥。登录 OpenAI 网站并前往 API 密钥管理页面即可完成此操作。
  • 在本地机器上安装 Docker,以便运行 APISIX 和 Spring Boot。

第 1 步:设置 Spring Boot 应用程序

首先,需要创建一个新的 Spring Boot 应用程序。可以使用 Spring Initializr 生成一个具有必要依赖项的 Maven 项目。在本教程中,将需要添加 Spring Boot Starter Web 依赖项。为了集成 ChatGPT API,可以使用 OpenAI Java 客户端库,这是一个开源的社区库,提供了在 Java 中创建和调用 OpenAI GPT API 的服务类。当然,也可以在 Spring 中编写自己的实现,以与 OpenAI API 进行交互。此外,还可以参考其他编程语言的客户端库。

<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>com.theokanning.openai-gpt3-java</groupId>
<artifactId>service</artifactId>
<version>0.12.0</version>
</dependency>
</dependencies>

第 2 步:创建 Controller 类

ChatCompletionController.java 类中,可以使用 OpenAI 服务向 ChatGPT API 发送请求。

import com.theokanning.openai.completion.chat.ChatCompletionChoice;
import com.theokanning.openai.completion.chat.ChatCompletionRequest;
import com.theokanning.openai.completion.chat.ChatMessage;
import com.theokanning.openai.completion.chat.ChatMessageRole;
import com.theokanning.openai.service.OpenAiService;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

import java.util.ArrayList;
import java.util.List;

@RestController
public class ChatCompletionController {

@Value("${openai.model}")
private String model;

@Value("${openai.api.key}")
private String openaiApiKey;

@PostMapping("/ai-chat")
public String chat(@RequestBody String prompt) {
OpenAiService service = new OpenAiService(openaiApiKey);
final List<ChatMessage> messages = new ArrayList<>();
final ChatMessage systemMessage = new ChatMessage(
ChatMessageRole.USER.value(), prompt
);
messages.add(systemMessage);

ChatCompletionRequest chatCompletionRequest = ChatCompletionRequest.builder()
.model(model)
.messages(messages)
.maxTokens(250)
.build();

List<ChatCompletionChoice> choices = service.createChatCompletion(chatCompletionRequest).getChoices();

if (choices == null || choices.isEmpty()) {
return "No response";
}

return choices.get(0).getMessage().getContent();
}
}

聊天 API 端点处理 POST 请求,创建聊天请求,并将其发送到 OpenAI API。然后,返回 API 响应中的第一条消息。端点地址为 /ai-chat

第 3 步:定义应用程序属性

application.properties 文件中定义 API 属性,包括模型和 API 密钥:

openai.model=gpt-3.5-turbo
openai.api.key=YOUR_OPENAI_API_TOKEN

请将 YOUR_OPENAI_API_TOKEN 替换为实际的 OpenAI API 密钥。

第 4 步:运行 Spring Boot 应用程序

现在,可以运行 Application.java 并使用 Postman 或 cURL 命令对其进行测试。

运行 Application.java 后,使用 Postman 或 cURL 发送请求来测试应用程序。以下是 cURL 请求的示例:

curl -X POST http://localhost:8080/ai-chat
-H "Content-Type: application/json"
-d '{"prompt": "What is Apache APISIX?"}'

如上所示,应用程序将根据提示请求正文生成回答。

第 5 步:创建 Dockerfile

接下来,为了将 Spring Boot 应用程序容器化,可以创建一个 Dockerfile,用于构建 JAR 文件并执行它。以下是一个示例 Dockerfile

# 使用官方 Java 运行时作为基础镜像
FROM openjdk:17-jdk-alpine

# 将 JAR 文件复制到容器中
COPY target/openaiapi.jar /app/openaiapi.jar

# 设置容器启动命令
ENTRYPOINT ["java", "-jar", "/app/openaiapi.jar"]

然后,在 docker-compose.yml 文件中注册服务,将应用程序与其他 APISIX 容器一起配置:

version: '3'
services:
openaiapi:
build: ./openaiapi
ports:
- "8080:8080"
networks:
- apisix

networks:
apisix:

这将构建 Spring Boot 应用程序的 Docker 镜像,并在 8080 端口上暴露它,使其可以与 APISIX 进行集成。

第 6 步:设置 Apache APISIX

要配置 Apache APISIX,只需运行以下命令,因为 docker-compose.yml 文件已定义了所需的服务。该文件配置了两个容器,一个用于 APISIX,另一个用于之前创建的 Spring Boot 应用。在本示例中,APISIX 以独立模式运行,其他安装选项和部署模式也可供选择。运行以下命令启动服务:

docker compose up

此时,APISIX 将作为一个单独的服务运行在 localhost:9080 上,而 Spring Boot 应用程序则在 localhost:8080 上运行。

第 7 步:使用 APISIX 保护 API

在设置完 APISIX 后,可以通过以下步骤为 Spring Boot API 添加安全功能,以确保只有授权的 API 消费者能够访问该 API。APISIX 提供了多种插件用于 API 保护,例如 jwt-auth 插件,可以要求所有请求必须使用 JWT 令牌。以下是如何在 apisix.yml 文件中配置带有上游服务和插件的路由示例:

upstreams:
- id: 1
type: roundrobin
nodes:
"openaiapi:8080": 1

routes:
- uri: /ask-me-anything
upstream_id: 1
plugins:
proxy-rewrite:
uri: /ai-chat
jwt-auth: {}

- uri: /login
plugins:
public-api:
uri: /apisix/plugin/jwt/sign

consumers:
- username: appsmithuser
plugins:
jwt-auth:
key: [email protected]
secret: my-secret-key

apisix.yml 文件中定义了上游服务、路由、消费者对象及其规则后,APISIX 将在 Docker 容器启动后立即加载这些配置文件。APISIX 会定期检测配置文件是否有更新,并在检测到变化时自动重新加载配置。

在此配置中,添加了一个上游服务、两个路由和一个消费者对象。第一个路由配置要求所有请求(自定义 URI 路径,可根据需要修改)必须在请求头中包含有效的 JWT 令牌。APISIX 使用 proxy-rewrite 插件将自定义的 URI 路径重写为实际的 API 路径,并将请求转发到运行在 localhost:8080 的 Spring Boot 应用程序。

如果尝试访问 APISIX 路由而未提供有效的 JWT 令牌,请求将被拒绝,返回授权错误:

curl -i http://localhost:9080/ask-me-anything -X POST -d '{"prompt":"What is Apache APISIX?"}'

响应示例:

HTTP/1.1 401 Unauthorized
{"message":"Missing JWT token in request"}

在第二个路由配置中,启用了 public-api 插件,以公开新的端点用于生成新的 JWT 令牌。APISIX 充当身份提供者,可以为 API 消费者或客户端应用程序生成和验证新令牌。请参阅第 8 步了解如何为 API 使用者生成新令牌:

- uri: /login
plugins:
public-api:
uri: /apisix/plugin/jwt/sign

此外,配置文件中注册了一个 API 消费者,允许用户使用其 secret 来声明 JWT 令牌,以访问 API:

consumers:
- username: appsmithuser
plugins:
jwt-auth:
key: [email protected]
secret: my-secret-key

第 8 步:领取新的 JWT 令牌

要为现有的 API 使用者获取新的 JWT 令牌,可以使用以下 cURL 命令。您需要替换 user-key 为实际的 API 使用者密钥:

curl -i http://127.0.0.1:9080/login?key=user-key

成功执行后,APISIX 将返回一个新的 JWT 令牌。响应示例如下:

HTTP/1.1 200 OK
Server: APISIX/3.0.0
Content-Type: application/json

{
"token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJrZXkiOiJ1c2VyLWtleSIsImV4cCI6MTY4NjU5MjE0NH0.4Kn9c2DBYKthyUx824Ah97-z0Eu2Ul9WGO2WB3IfURA"
}

您可以将返回的 JWT 令牌用于后续 API 请求。在请求中,您需要将此令牌放在 Authorization 头中,以便验证请求的合法性:

curl -i http://localhost:9080/ask-me-anything -X POST -H "Authorization: Bearer YOUR_NEW_JWT_TOKEN" -d '{"prompt":"What is Apache APISIX?"}'

这将确保只有持有有效 JWT 的请求才能访问受保护的 API 端点。

第 9 步:使用 JWT 令牌请求 API

最后,可以使用从上一步中获取的 JWT 令牌向 API 发送请求。以下是如何使用 cURL 命令进行请求的示例:

curl -i http://localhost:9080/ask-me-anything
-H 'Authorization: Bearer YOUR_JWT_TOKEN'
-X POST
-d '{ "prompt": "What is Apache APISIX?" }'

YOUR_JWT_TOKEN 替换为实际的 JWT 令牌。

此外,也可以使用 Postman 发送相同的请求。确保在请求头中添加 Authorization,其值为 JWT 令牌。请求成功后,将从 APISIX 网关收到 AI 的响应。

结论

本教程介绍了如何利用 OpenAI ChatGPT API 生成对提示的响应。首先创建了一个 Spring Boot 应用程序,该应用程序通过调用 API 生成响应。随后,通过更新现有的 apisix.yml 文件,可以为集成引入其他功能。此外,还可以查看名为 with-frontend 的分支,并运行项目,以查看使用 Appsmith 构建的与 APISIX 配合使用的 UI 界面。

什么是通用API管理平台?

通用API管理包括传统API管理之外的扩展功能集。第一个是能够将API管理扩展到多个供应商网关、部署模式和存储库(有时称为“联合API管理”)。第二个是处理基本SOAP和REST之外的其他API模式的能力。这包括GraphQL,Events,Service Mesh,gRPC和AsyncAPI。

简单来说,一个真正通用的API管理平台应该能够提供对无论在哪里、以何种形式存在的API的可见性和控制。

如何实现通用API管理?

有几种方法可以实现通用API管理。使用轻量级、非侵入式代理与所有不同的API数据平台(Axway、AWS、Azure、Apigee、Mulesoft.)进行接口。

这些代理不位于数据路径中(与某些供应商使用的代理方法不同,该方法可能会增加成本、延迟和部署时间),并允许常见的发现、可观察性和订阅。

真正开放的通用API管理方法意味着多云、多协议和多网关支持,同时还可以摆脱供应商锁定。

是什么推动了通用API管理平台的发展趋势?

大约13年前,API倡导者金·莱恩(Kin Lane)首次提出了“API经济”的概念,但时至今日,它依然与当时一样重要,甚至更加重要。每个行业都能从使用推动新型商业模式的API中受益;毕竟,API并非仅为科技公司服务。但是,API技术的这种迅速增长和不断演进却迎来了API复杂性提升的新挑战时代。

1.庞大的业务部门构建自己的API

开发人员需要灵活性和独立性,以便使用适合他们的工具进行创新。但是,当业务部门各自独立地开发API时,您就会开始看到导致客户体验(CX)碎片化、管理耗时以及自动化和标准化方面出现难题的孤立现象。

它还可能导致资源的严重重复。两个不同的团队可能构建相同的API,而不知道已经有一个可用的API可以满足他们的目的。我们发现,公司每次重用一个API,平均可以节省近3万美元。

2.来自多个供应商的多个API网关

如今,平均每家企业都会使用3-4个不同的API管理供应商,在某些情况下甚至多达5个。他们这样做往往有充分的理由,希望区分外部和内部流量、本地部署和云部署,或者管理不同的功能。

对公司资产没有统一的看法可能会推迟新数字项目和产品的推出,或者更难吸引合作伙伴。然后,还有治理和安全问题。

通用API管理有什么好处?

通用API管理解决的问题是整个组织中进行API开发的复杂性。每个团队都有自己的工具、技术和任务。通用API管理平台使您能够:

  • 统一所有API资产并管理其生命周期,而无需考虑模式、部署或平台
  • 实现现代化,而无需拆除和替换现有的API解决方案
  • 实现更加业务驱动的战略
  • 从一个控制台监控、管理和治理所有API
  • 从通用API市场推动采用和货币化。

谁需要通用API管理?

API平台团队

通过操作所有API来掌握API复杂性。获得完整的运营视图沿着使用率和性能指标,以更低的成本增加服务交付。

API消费者

缩短推动数字业务的API的价值实现时间。通过轻松查找和使用经过安全验证、文档完整且可投入生产的成熟API产品,使开发人员能够加快计划的交付。

数字化业务线索

通过促进更多的API采用,提高API的投资回报率。通过推广精心策划的API产品(而不是您曾经生产过的每一个API),降低进入门槛并推动数字业务计划的消费。

如何发现更多API

幂简集成是国内领先的API集成管理平台,专注于为开发者提供全面、高效、易用的API集成解决方案。幂简API平台可以通过以下两种方式找到所需API:通过关键词搜索API(例如,输入’IP地址定位‘这类品类词,更容易找到结果)、或者从API Hub分类页进入寻找。

此外,幂简集成博客会编写API入门指南、多语言API对接指南、API测评等维度的文章,让开发者快速使用目标API。

Metal 3D Printing – How Does it Work?

What Is Metal 3D Printing?

Metal 3D printing is a revolutionary technology that produces impossible-to-make parts directly from CAD data. Advantages to this process include the ability to produce strong, complex geometries, internal lattice structures, conformal cooling channels and other features that cannot be made with traditional machining. Parts can be made quickly with a minimum of material waste making them ideal for next-generation engineering in aerospace, medical, automotive and other industries.

One of the main 3D printing processes is called Direct Metal Laser Melting (DMLM). This additive manufacturing process uses a high-powered laser to melt and fuse successive layers of powdered metal into three-dimensional solid parts. The advantage is that the more complex or feature rich the component, the more economical the process becomes. Direct Metal Laser Melting creates parts that are 99% dense, meaning they are as strong as forged pieces while being lighter.


Advantages Of 3D Printing

There are many benefits for 3D printing, especially if you know how to optimize your product design to take advantage of them. Benefits include:

  • Metal 3D printed parts are fully dense, incorporating complex geometries and precise internal features that cannot be made with traditional machining alone.
  • Designs can be made quickly with a minimum of material waste while maximizing strength.
  • Conformal cooling channels greatly improve performance and resistance to thermal stress, ideal for aerospace and automotive applications.
  • Multiple, identical parts can be built on a single platform at one time, greatly increasing production efficiency

Metal 3D Printing Process

First a 3D CAD file must be provided for the design. In order to achieve the best results, it’s essential that engineers review your CAD drawing file in advance and optimize the design wherever necessary. This may include optimizing build orientation and adding support structures to areas where the force of gravity can cause features to distort during the printing process. These supports will later be removed.

Specialized software should then be used to slice the drawing into multiple cross-sectional layers, with each layer representing a 20 – 60μm thickness of the final shape. Finally, the sliced file should be uploaded into the machine to be printed. An example of the kind of machine best for this work is the Renishaw AM250, a state-of-the-art metal 3D printer for rapid prototyping and manufacturing.

Post-Machining Services

Many people are excited by the new possibilities of 3D printing, and for good reason. However, despite being able to make complex designs possible, there are still some inherent limitations. 3D printing is not ideal for making fine surface finishes, accurate holes, threads or flat smooth mating surfaces.

Metal 3D printing almost always requires some form of post-machining to provide features that 3D printing alone cannot. Excess material is usually removed by CNC milling and turning, drilling or grinding. Star Rapid have a range of other finishing processes to ensure that you get the final look you want.

What qualities should you look for in a 3D printing service provider?

Depth and breadth distinguish the best metal 3D printing service from others in the industry. Using a state-of-the-art machinery, like the Renishaw AM250 printer, the service provider can successfully produce impossible-to-make parts directly from your CAD data. The service provider should also offer 3D metal printing in several materials, including titanium, stainless steel, maraging steel and aluminum. Ensure that there are rigorous quality standards in place. They should start during reviews of submitted CAD files, where designs are analyzed and suggestions provided for improvements, if necessary. If using a Renishaw printer, all metal powders should be sourced from Renishaw and be formulated specifically for the printer.

Star Rapid no longer offers metal 3D printing services. However, we remain fully committed to helping our customers reach their product development goals by offering a variety of rapid prototyping and low-volume manufacturing services.

Metal 3D Printing Used to Craft Unique Jewelry Designs

New-York-based jewelry designer and goldsmith Veronica Nunes takes inspiration from nature and architecture to create flattering pieces for her jewelry brand VNunes. When she came to us to make her creations come to life, we used our metal 3D printing service to input her intricate designs and output meticulously-shaped finished products. We worked closely with Veronica to fine-tune her designs for maximum aesthetic appeal and structural integrity, focusing on several specific areas, including wire detailing, blade detailing, overhang, and moving parts. Read our case study to learn more.

Metal 3D Printing for Conformally Cooled Mold Tools

All injection mold tools must be cooled to maximize efficiency and ensure consistent product quality. Traditionally, these tools have been cooled using linear paths, which have their limitations in terms of cooling effectiveness. To improve the results for a water reservoir for Marco Beverage, we made new molds using conformal cooling paths that “conform” to the shape of the mold itself and maximize cooling efficiency. These new 3D-printed metal parts reduced cooling time by as much as 60% over identical molds with traditional cooling paths. Explore the details here.
