使用aws-cli在AWS API Gateway中启用CORS [英] Enable CORS in AWS API Gateway with aws-cli

问题描述

我目前正在编写脚本，以在将资源添加到AWS API Gateway上的API端点后以编程方式启用CORS.在研究了放置积分响应功能达数小时之后.我几乎取得了突破，但是这是我遇到的错误:

I'm currently writing script to programmatically enable CORS once a resource is added to an API Endpoint on AWS API Gateway. After exploring the put-integration-response function for hours. I almost got a breakthrough, but here is an error I'm getting:

An error occurred (BadRequestException) when calling the 
PutIntegrationResponse operation: Invalid mapping expression specified: 
Validation Result: warnings : [], errors : [No method response exists 
for method.]

这是我用来启用CORS的脚本:

Here is the script I'm using to enable CORS:

aws apigateway put-integration-response --rest-api-id XXXXX --resource 
-id XXXX --http-method GET --status-code 200 --selection-pattern 200 -- 
response-parameters '{"method.reponse.header.Access-Control-Allow- 
Origin": "'"'*'"'", "method.response.header.Access-Control-Allow- 
Headers": "'"'integration.request.header.Authorization'"'"}'

我发现奇怪的是，AWS文档似乎与 aws-cli 的当前版本不合时宜.我花了很多时间来解决api调用遇到的一些基本问题.

The weird thing I found was the AWS documentation seems to be out of date with the current version of the aws-cli It tooks me hours to fix some basic issues I had with the api call.

将对任何想法表示感谢.

Will be grateful for any ideas.

干杯！Nyah

推荐答案

在您的AWS CLI命令中发现的 aws apigateway put-integration-response

Couple of issues found in your AWS CLI command for aws apigateway put-integration-response

1. 有错别字

method.reponse.header.Access-Control-Allow-Origin

method.reponse.header.Access-Control-Allow-Origin

它必须是:

   method.response.header.Access-Control-Allow-Origin

1. 要为 Access-Control-Allow-Origin 设置值'*'，您需要改用'"'"**""" 的'"'*''" 在响应参数中，您可以设置 method.reponse.header.Access-Control-Allow-Origin ，但不能设置 method.response.header.Access-Control-Allow-Headers
2. 错误原因

1. To set a value '*' to Access-Control-Allow-Origin you need to use "'"'"'*'"'"'" instead of "'"'*'"'" In response-parameters you can set method.reponse.header.Access-Control-Allow-Origin, but can not set method.response.header.Access-Control-Allow-Headers
2. The reason of the error

PutIntegrationResponse操作:指定了无效的映射表达式

PutIntegrationResponse operation: Invalid mapping expression specified

是因为您试图在 response-parameters

下面应该是最终的AWS CLI命令

Below should be the final AWS CLI command

aws apigateway put-integration-response --rest-api-id XXXXX --resource-id XXXX --http-method GET --status-code 200 --selection-pattern 200 
--response-parameters '{"method.reponse.header.Access-Control-Allow-Origin": "'"'"'*'"'"'"}'
