我知道有很多关于映射请求数据的问题,但都没有人帮助我。 所以,我试图实现的是一个映射到lambda的API端点。当一个桶触发一个404并且参数通过请求路径传递给lambda时,对该端点的请求被转发,如:/ {image_name}/{width}/{height}。 我拉姆达的代码只需调用context.succeed(event, context);
AWS ApiGateway请求路径映射+ lambda
在我已经创建了三个映射模板的合并请求:纯/文本,一般/ HTML,应用/ JSON具有相同的定义波纹管:
#set($inputRoot = $input.path('$'))
{
"name": $input.params('name'),
"width" : $input.params('width'),
"height" : $input.params('height'),
"params": $input.params(),
"resourcePath": $context.resourcePath,
}
当调用形成铬REST客户端,我得到:
当调用从控制台的测试,我得到以下回应: {"Type":"User","message":"Could not parse request body into json."}
相同的反应,当我打电话卷曲或当我只需在浏览器中打开URL我得到。
但是从控制台的测试日志叫我看:

正如我在某些时候看到的,URL路径是否正确解析,但我不知道哪里出了问题。 另外,我不知道为什么X-Amz-Source-Arn中存在路径中的空值。
谢谢。
这应该被接受的答案 – ken
