发出OPTIONS请求时发生AWS API网关错误
我正在使用CFT为我的API创建环境。我已经添加了CORS的选项。我已经注意到，当我从AWS console for OPTIONS上做测试时，我得到了200响应。然而，当我在CURL or PostMan中执行同样的操作时，我得到了500内部服务器错误。在回顾了与之相关的SO问题之后。我已经将集成响应修改为CONVERT_TO_TEXT。但这也没有解决问题。
我在日志中注意到一种有线行为。以下是来自AWS控制台的请求的日志片段：
Sat Apr 13 15:06:26 UTC 2019 : Method request headers: { Access-Control-Request-Method= POST, Content-Type= application/json}
Sat Apr 13 15:06:26 UTC 2019 : Method request body before transformations:
Sat Apr 13 15:06:26 UTC 2019 : Method response body after transformations:
Sat Apr 13 15:06:26 UTC 2019 : Method response headers: {X-Requested-With=*, Access-Control-Allow-Headers=Content-Type,X-Amz-Date,Authorization,X-Api-Key,X-requested-with, Access-Control-Allow-Origin=*, Access-Control-Allow-Methods=POST,OPTIONS, Content-Type=application/json}
Sat Apr 13 15:06:26 UTC 2019 : Successfully completed execution
Sat Apr 13 15:06:26 UTC 2019 : Method completed with status: 200但是，当我从CRUL或PM发出同样的请求时，我看到了以下日志：
Method request path: {}
Method request query string: {}
Method request headers: Method request headers: {Accept=*/*, CloudFront-Viewer-Country=IN, CloudFront-Forwarded-Proto=https, CloudFront-Is-Tablet-Viewer=false, CloudFront-Is-Mobile-Viewer=false, User-Agent=curl/7.55.1, X-Forwarded-Proto=https, CloudFront-Is-SmartTV-Viewer=false, Host=MYHOST, X-Forwarded-Port=443, (CloudFront), Access-Control-Request-Method=POST, CloudFront-Is-Desktop-Viewer=true, Content-Type=application/json}
Method request body before transformations: [Binary Data]
Execution failed due to configuration error: Unable to transform request
Method completed with status: 500我们可以看到它正在尝试转换[Binary Data]，但我没有发送任何东西。
我使用的Curl是：curl -X OPTIONS -H "Access-Control-Request-Headers: Content-Type" -H "Access-Control-Request-Method: POST" -H "Access-Control-Allow-Origin: '*'" -v MYHOST
为什么我在日志中看到了这种差异？我的配置出了什么问题？你能帮帮我吗。

似乎有一个文档较少的要求将contentHandling: CONVERT_TO_TEXT参数添加到两者:集成请求和集成响应设置。
在swagger CORS配置中，如下所示：
responses: {
200: {
description: "Returning CORS headers",
headers: {
"Access-Control-Allow-Headers":{ type: "string" },
"Access-Control-Allow-Methods": { type: "string" },
"Access-Control-Allow-Origin": { type: "string" },
}
}
},
"x-amazon-apigateway-integration": {
type: "mock",
contentHandling: "CONVERT_TO_TEXT", // Resolves problems with cloudfront binary content issues
requestTemplates: {
"application/json": "{ \"statusCode\": 200 }"
},
responses: {
"default": {
statusCode: "200",
contentHandling: "CONVERT_TO_TEXT", // Resolves problems with cloudfront binary content issues
responseParameters: {
"method.response.header.Access-Control-Allow-Headers": "'*'",
"method.response.header.Access-Control-Allow-Methods" : "'*'",
"method.response.header.Access-Control-Allow-Origin" : "'*'"
},
responseTemplates: {
"application/json": "{}"
}
}
}

如果在你的API网关设置中，你已经将'application/json‘添加到了二进制媒体类型(比如你想要gzip响应的情况下)，或者如果这个请求是针对二进制媒体类型的，那么由'enable CORS’功能添加的默认选项将需要调整。
正如上面所说的，至少对于集成来说，您需要将contentHandling设置为"CONVERT_TO_TEXT“。对我来说，它无需将其添加到集成响应中即可工作。您可以通过AWS CLI执行此操作，如下所示：
aws apigateway update-integration --rest-api-id YOUR_REST_ID --resource-id YOUR_RESOURCE_ID --http-method OPTIONS --patch-operations op='replace',path='/contentHandling',value='CONVERT_TO_TEXT'哦，之后别忘了重新部署API。
