我正在尝试执行签名的可恢复地上传到GCS

I'm trying to perform a signed resumable upload to GCS. Our frontend is running up against CORS restrictions on the initial request: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

响应标头不显示CORS标头:

The response headers show no CORS headers:

alt-svc: quic=":443"; ma=2592000; v="44,43,39,35" cache-control: private, max-age=0 content-length: 0 content-type: text/html; charset=UTF-8 date: Tue, 13 Nov 2018 20:28:32 GMT expires: Tue, 13 Nov 2018 20:28:32 GMT server: UploadServer status: 200 x-guploader-uploadid: AEnB2Ups1tKbTbhPmsjrPXbIuIUyQt135AlSJ1n7-7XTwMrtQ2vUvn1WwpX3a_iusfmsXHaufdf5B3H2PzmDONs2wW7tKkLarYoxrVyWalhaX6FzGQPoRW0

调试时，我发送了一个卷曲请求，模仿了我们前端的请求:

Debugging, I sent a curl request mimicking our frontend's request:

curl -H "Access-Control-Request-Headers: content-type,x-goog-resumable" \ -H "Access-Control-Request-Method: POST" \ -H "Origin: www.example" \ -X OPTIONS -I storage.googleapis/bucket/...

同样，响应中不包含CORS响应标头:

Again, the response contains no CORS response headers:

HTTP/2 200 x-guploader-uploadid: AEnB2UqwKiRSJjHjF9mzsZRMODdQmF6xhUAhdeEenuD0_WXmxpVA6n0i_HWY2NOJxvXS2t_I4IoFW_yvz6lssMz_HVmvlswL5NilGC3wE2YT0-L9aD7Pf1Q date: Tue, 13 Nov 2018 21:39:53 GMT expires: Tue, 13 Nov 2018 21:39:53 GMT cache-control: private, max-age=0 content-length: 0 server: UploadServer content-type: text/html; charset=UTF-8 alt-svc: quic=":443"; ma=2592000; v="44,43,39,35"

我已使用gsutil cors set cors.json gs://bucket设置了存储桶CORS设置，其中cors.json包含[{"maxAgeSeconds": 3600, "method": ["GET", "POST", "PUT", "OPTIONS"], "origin": ["*"]}]

I've set my bucket CORS settings with gsutil cors set cors.json gs://bucket where cors.json contains [{"maxAgeSeconds": 3600, "method": ["GET", "POST", "PUT", "OPTIONS"], "origin": ["*"]}]

我在这里想念东西吗?

推荐答案

我找到了一个解决方案.我必须在响应标头列表中添加x-goog-resumable.

I have found a solution. I had to add x-goog-resumable to the list of response headers.

我的CORS文件是

[ { "origin": ["*"], "responseHeader": [ "Content-Type", "Access-Control-Allow-Origin", "x-goog-resumable"], "method": ["GET", "HEAD", "DELETE", "POST", "OPTIONS"], "maxAgeSeconds": 3600 } ]

至少预检开始起作用
