Question

我正在尝试将大型文件从iOS上传到服务器

我的代码启动webservce，上传~180000字节后，它会挂起，等待，并最终超时。

正如代码目前所在。（我已经改变了很多尝试进行故障排除）

AFHTTPClient *uploadClient = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:k_WebService_Root]];


NSMutableDictionary *parameters = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   @"secret"                  , @"Token",
                                   nil];
NSDictionary *requestObject = [NSDictionary dictionaryWithObject:parameters forKey:@"request"];
NSString *endpoint = [self makeEndpointWithService:k_ServiceEndpoint_Message andAction:k_WebService_Message_Upload];

NSMutableURLRequest *request = [uploadClient multipartFormRequestWithMethod:@"POST" path:endpoint parameters:requestObject constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    NSData *data = [NSData dataWithContentsOfFile: videoFile.path];
    [formData appendPartWithFileData:data name:@"file" fileName:@"message.mov" mimeType:@"video/quicktime"];
}];

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];

[operation setUploadProgressBlock:^(NSInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
    NSLog(@"Sent %lld of %lld bytes", totalBytesWritten, totalBytesExpectedToWrite);
}];

[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Success");
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Fail\n%@", error);
}];


[operation start];

输出始终如下所示

然后几分钟后我从AFNetworking获得了超时

任何想法？

更新::: 显然它只在通过3G上传时发生

Answer 1

这似乎更像是服务器端问题。您是否检查过服务器是否正确接收了数据？

Answer 2

事实证明iOS限制上传3G。我无法在Apple的任何地方找到此文件。

然而亚马逊为s＃http://aws.amazon.com/articles/0006282245644577解决了这个问题 AFNetworking有一个开发分支（7/31/12）https://github.com/AFNetworking/AFNetworking/pull/418

过时的ASIHTTPRequest处理它，是我唯一的希望http://allseeing-i.com/ASIHTTPRequest/How-to-use#throttling_bandwidth

祝所有遇到此事的人好运。

AfNetworking上传停止并最终仅通过3G超时
