The following quotas are given at GAE docs:
- request size: 1 megabyte
- response size: 32 megabytes
If my GAE app receives upload file, 1 megabyte quota is applied? If my GAE app sends (POST) the file to another server with urlfetch, still 1 megabyte is the the limit?
回答1:
Imcoming bandwidth quota: Each incoming HTTP request can be no larger than 32MB.
So an HTTP request from a browser directly to your application (suchas uploading a file) cannot exceed 32MB.
Urlfetch quota: request size 1 megabyte
So you can't POST a request larger than 1MB using urlfetch
If you need to have an outside service process large files from your app; Upload the files into the blobstore, and then post a link to the external service so that it can fetch the file. If you do not control the external service, and their api does not have a method for fetching files via URL, you might have to rethink and maybe send the file to the external service first rather that to your AE app.
