如何在AWS api网关中正确使用集成响应映射以返回不同的http代码 [英] how to correctly use integration response mapping in aws api gateway to return different http codes

问题描述

我似乎无法使用Amazon api网关为错误设置集成响应

I can't seem to set my integration response for errors using the amazon api gateway

我添加了一个集成响应，但是它不返回400错误，而是继续返回200响应，

I added an integration response but it does not return the 400 error, instead it continues to return 200 response with

{
  "errorMessage": "foose",
  "errorType": "Error",
  "stackTrace": [
    "exports.handler (/var/task/index.js:11:19)"
  ]
}

推荐答案

如果您使用的是Java，则需要抛出异常.我犯了尝试返回错误信息的错误. Lambda错误正则表达式会解析Exception消息，因此，如果抛出此消息:

If you are using the Java, you need to throw an Exception. I made the mistake of trying to return the error information. The Lambda Error Regex parses the Exception message so if you throw this:

throw new Exception("Failed: Something bad happened!");

，然后将foo.*替换为Failed: .*，它将使用400状态代码.

and replace your foo.* with Failed: .* it will use the 400 status code.

如果您使用的是NodeJS，则可以使用context.fail('Failed: Something bad happened!');获得相同的结果

If you are using NodeJS, you can use context.fail('Failed: Something bad happened!'); to get the same result
