使用签名的URL从iOS超时发布到S3 [英] Timeout POSTING to S3 from iOS using signed URLS
问题描述
我的服务器正在生成用于签名上传到S3的信息.当我将该信息传递给iOS时，它适用于小文件.有时，它也适用于较大的产品，但通常会超时.我目前正在通过WIFI在iOS 7上进行测试.通常，在大约35 MB的文件上大约有60％的时间后会超时，但有时它会完成，有时会更快地超时.
My server is generating info for a signed upload to S3. When I pass that info on to iOS, it works for small files. Sometimes it works for bigger ones as well, but it often times out. I am currently testing on iOS 7 over WIFI. It's typical for it to time out after about 60% on an approximately 35 MB file, but sometimes it completes and sometimes it times out sooner.
我的服务器生成以下信息，这些信息作为表单的一部分传递给POST. (我也尝试将其作为参数使用，结果相似):
My server generates the following info, which I pass on as form parts to my POST. (I also tried it as parameters with similar results):
- AWSAccessKeyId
- 内容类型
- acl(设为私有)
- 斗
- 键
- 政策
- 签名
- success_action_redirect
以及网址.
这是我生成上传的代码:
Here is my code that generates the upload:
AFHTTPRequestOperation *op = [manager POST:url
parameters:nil
constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
{
if( throttle )
[formData throttleBandwidthWithPacketSize:kAFUploadStream3GSuggestedPacketSize delay:kAFUploadStream3GSuggestedDelay];
for( id key in parameters ) {
NSString *val = parameters[key];
[formData appendPartWithFormData:[val dataUsingEncoding:NSUTF8StringEncoding] name:key];
}
NSError *error;
if( ![formData appendPartWithFileURL:videoUrl name:@"file" fileName:@"movie.mov" mimeType:@"video/quicktime" error:&error] ) {
// handle the error
}
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
//success
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
if( error.code == -1021 && !throttle ) {
//try again with throttle:
}
NSLog(@"Error: %@", error);
// handle error
}];
这会产生以下错误:
Error: Error Domain=NSURLErrorDomain Code=-1001 "The request timed out." UserInfo=0x1aa15130 {NSErrorFailingURLStringKey=XXX, NSErrorFailingURLKey=XXX, NSLocalizedDescription=The request timed out., NSUnderlyingError=0x1ab94290 "The request timed out."}
更新:
我应该提到几个类似的问题.很多人在Heroku超时方面遇到麻烦，但是我直接上传到S3.
There are several similar questions on SO I should mention. A lot of people have trouble with Heroku timeouts, but I'm uploading directly to S3.
此人上传到自己的服务器上似乎也有同样的问题: -使用AFNetworking在iOS上上传大文件-错误请求超时
This person seems to have the same problem uploading to his own server: - Uploading large files on iOS with AFNetworking - error Request Timeout
这个问题看起来像使用AWS库的类似问题，但是它们不提供任何代码:
This question looks like a similar problem using the AWS library, but they don't provide any code:
这个问题似乎有关，但是从源头来看，发布文件时似乎考虑了长度:
This issue seems related, but looking at the source, it seems that length is taken into account when posting a file:

推荐答案
在视频文件(mp4文件)上也发生了这种情况. 问题是我的视频文件很小(最大2-5MB).
It happens to me on video files as well, mp4 files. The thing is that my video files are small (2-5MB max).
我正在使用AWSiOSSD 2.5.2，iPhone 6s 7和7plus以及10+版本(包括最新版本).
I'm using AWSiOSSD 2.5.2, iPhones 6s 7 and 7plus with versions 10+ (including the latest ver).
到目前为止，尚无解决方法，包括6个月前在此线程上发布的otusweb答案.
No workarounds worked so far, including otusweb answer posted 6 months ago on this thread.
