java - AWS API Gateway 生成 SDK 请求错误

Question

我已使用 AWS API Gateway 创建了一个 API。 API 中使用的所有方法都需要 IAM 身份验证。

我尝试在本地测试 API 并得到以下异常:

myapi.model.MyAPIException: The request signature we   calculated does not match the signature you provided. Check your AWS Secret  Access Key and signing method. Consult the service documentation for details.

    at com.amazonaws.opensdk.protect.client.SdkClientHandler.execute(SdkClientHandler.java:42)
    at myapi.MyAPIClient.myMethod(MyAPIClient.java:101)
    ...

为了构建请求，我使用了以下代码:

public static void main(String[] args) {

    MyAPI client = MyAPI .builder()
                .apiKey(myApiKey)
                .iamCredentials(DefaultAWSCredentialsProviderChain.getInstance())
                .build();

    MyMethodRequest myMethodRequest = new MyMethodRequest().arg(methodArg);

    MyMethodResult result = client.myMethod(myMethodRequest);
}

由 DefaultAWSCredentialsProviderChain 加载的凭证是我的凭证，它对我的​​所有 AWS 服务具有管理员访问权限，因此我不确定出了什么问题。

感谢任何帮助。

问题最终是因为为 API 输入了错误的 apiKey。当我将其更改为 API Gateway 生成的有效 API key 时，一切正常。

此外，您必须确保 API key 链接到有效的使用计划，否则它将不起作用
