从 API Gateway 触发 CodeBuild 时出现 com.amazon.coral.service#UnknownOperationException

Question

目前还没有专门集成 API 网关和 Codebuild 的实际指南，因此我正在研究几个并尝试适应。

我已根据本文档设置了我的角色和策略，并且已成功设置并运行了我的 CodeBuild 项目。

我已经设置了一个 POST 端点，参考CodeBuild API 文档中的操作：

我正在使用端点的测试选项卡来发送

{ "project": "my-project" }

但我得到了这个回应

{
  "Output": {
    "__type": "com.amazon.coral.service#UnknownOperationException",
    "message": null
  },
  "Version": "1.0"
}

Answer 1

在 HTTP headers 中，您应该定义这两个标头：

Content-Type = 'application/x-amz-json-1.1'
X-Amz-Target = 'CodeBuild_20161006.StartBuild'

起初我只添加了 X-Amz-Target 但我继续收到相同的错误，后来我在 github 问题中发现有人还将具有该值的 Content-Type 传递给请求，我尝试并工作了。

我希望这对将来的其他人有帮助。
