Amazon APi 网关无法生成转换后的请求

Question

我正在尝试将 Amazon API 网关与 Lambda 函数集成。虽然我成功地实现了，但是当我尝试使用 curl 时它失败了。

Lambda 方法，API 网关集成以及集成请求下的模板映射已设置。

当我从控制台运行 "test" 时，它工作正常

Execution log for request test-request 
Wed Nov 04 07:27:30 UTC 2015 : Starting execution for request: test-invoke-request
Wed Nov 04 07:27:30 UTC 2015 : API Key: test-invoke-api-key
Wed Nov 04 07:27:30 UTC 2015 : Method request path: {service=xml}
Wed Nov 04 07:27:30 UTC 2015 : Method request query string: {}
Wed Nov 04 07:27:30 UTC 2015 : Method request headers: {}
Wed Nov 04 07:27:30 UTC 2015 : Method request body before transformations: Articletext
Wed Nov 04 07:27:30 UTC 2015 : Endpoint request body after transformations: {
  "prog" : "xml",
  "content" : "Articletext",
  "test" : "{path={service=xml}, querystring={}, header={}}"
}

但是当我尝试通过 curl 访问它时，它无法在转换后创建适当的正文

curl -X POST https://aaaaaaa.execute-api.us-west-2.amazonaws.com/beta/apitest/xml -H "Content-Type: application/x-www-form-urlencoded; charset=UTF-8" --data-binary "Articletext"

Starting execution for request: 
Method request path: {service=xml}
Method request query string:
{}
Method request body before transformations: Articletext
Endpoint request body after transformations: Articletext
Endpoint response body before transformations:
{
    "Type": "User",
    "message": "Could not parse request body into json."
}

任何人都可以建议我有关缺少的部分吗？

Answer 1

请确保您的内容类型与您在集成请求模板中定义的相同。

你可以试试这个 curl 命令。

curl -X POST https://aaaaaaa.execute-api.us-west-2.amazonaws.com/beta/apitest/xml -H "Content-Type: application/json" --data-binary "Articletext"

在我的例子中，问题是我没有部署 API，所以它没有更新供外部使用。参见
