最近灰常火爆，已经成为最有效率的生产工具，认人感觉人工智能的时代来临了。今天聊一下如何快速接入。
一、准备工作
如果想在 Boot应用程序中使用提供的 API，可以按照以下步骤进。
注册账户并创建API密钥
首先，您需要注册账户，并创建一个API密钥。API密钥可以用于调用提供的各种API，包括 API。具体的注册和创建API密钥步骤可以参考的官方文档。注册完即可创建API key，网址：
注意：生成API密钥后，如果关闭弹窗，不会再次显示API密钥，所以需要把它保存下来，以便下次能找回它。
引入-gpt3-java依赖
接下来，需要在项目的pom.xml文件中添加以下-gpt3-java依赖，目前最新版本为0.11.1：
com.theokanning.openai-gpt3-java
service
0.11.1
创建，调用 API
@RestController
public class ChatGPTController {
private String OPENAPI_TOKEN = "YOUR_API_KEY";
private Duration TIMEOUT = Duration.ofSeconds(30L);
private String MODEL = "text-davinci-003";
@PostMapping("/chat")
public String chat(@RequestBody ChatMessage input) {
OpenAiService service = new OpenAiService(OPENAPI_TOKEN, TIMEOUT);
CompletionRequest.CompletionRequestBuilder builder = CompletionRequest.builder()
.model(MODEL)
.prompt(input.getInput())
.maxTokens(1000);
CompletionRequest completionRequest = builder.build();
List questionAnswer = service.createCompletion(completionRequest).getChoices();
String endQuestionAnswer = "";
for (CompletionChoice completionChoice : questionAnswer) {
endQuestionAnswer = endQuestionAnswer.concat(completionChoice.getText());
}
return endQuestionAnswer;
}
}
@Data
public class ChatMessage {
private String input;
}测试
完成接口编写后，下面启动程序，打开页面进行测试：
二、参数分析
是一个用于向 GPT-3 API发送请求的对象，它包含了多个可选参数，以定制化生成的文本。以下是其中一些重要参数的意义：
这些参数并非全部，您可以查看 API文档以了解所有可用参数。在实际使用中，您需要根据生成的文本需要进行相应的参数调整。
三、其它
调用 API需要科学上网环境，这个是前提。
如果调用 接口出现You your quota, check your plan and 异常，就是账户里面没钱了，需要付费才能使用。注册的第一个账号会有5美元的免费token配额，注册的第二个及以后的账号就无免费api token配额了。
下面是请求 API的一些常见错误：
CODE OVERVIEW
401 - Invalid Authentication
Cause: Invalid Authentication
Solution: Ensure the correct API key and requesting organization are being used.
解释：认证错误，有可能是API key错误
401 - Incorrect API key provided
Cause: The requesting API key is not correct.
Solution: Ensure the API key used is correct, clear your browser cache, or generate a new one.
解释：跟401类似，也是API key的问题
401 - You must be a member of an organization to use the API
Cause: Your account is not part of an organization.
Solution: Contact us to get added to a new organization or ask your organization manager to invite you to an organization.
解释：暂时没遇到此问题
429 - Rate limit reached for requests
Cause: You are sending requests too quickly.
Solution: Pace your requests. Read the Rate limit guide.
解释：每分钟请求次数太多了，免费的每分钟最多20次
429 - You exceeded your current quota, please check your plan and billing details
Cause: You have hit your maximum monthly spend (hard limit) which you can view in the account billing section.
Solution: Apply for a quota increase.
解释：账户里面没钱了
429 - The engine is currently overloaded, please try again later
