Question

我无法使用AFNetworking NSMutableURLRequest上传图片 - 它总是超时。

我可以向同一台服务器发出成功GET次请求：

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:@"http://example.com/resources.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

但AFNetworking NSMutableURLRequest总是超时。我的代码如下所示：

// 1. Create AFHTTPRequestSerializer which will create your request.
AFHTTPRequestSerializer *serializer = [AFHTTPRequestSerializer serializer];

// 2. Create an NSMutableURLRequest.
NSMutableURLRequest *request =
[serializer multipartFormRequestWithMethod:@"POST" URLString:@"http://192.168.0.105/upload2.php"
                                parameters:nil
                 constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
                     [formData appendPartWithFileData:imageData
                                                 name:@"upfile"
                                             fileName:@"file://Users/wangyan/Downloads/idcard.png"
                                             mimeType:@"image/jpeg"];
                 }];

// 3. Create and use AFHTTPRequestOperationManager to create an AFHTTPRequestOperation from the NSMutableURLRequest that we just created.
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
AFHTTPRequestOperation *operation =
[manager HTTPRequestOperationWithRequest:request
                                 success:^(AFHTTPRequestOperation *operation, id responseObject) {
                                     NSLog(@"Success %@", responseObject);
                                 } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
                                     NSLog(@"Failure %@", error.description);
                                 }];

// 4. Set the progress block of the operation.
[operation setUploadProgressBlock:^(NSUInteger __unused bytesWritten,
                                    long long totalBytesWritten,
                                    long long totalBytesExpectedToWrite) {
    NSLog(@"Wrote %ld/%ld", (long)totalBytesWritten, (long)totalBytesExpectedToWrite);
}];

// 5. Begin!
[operation start];

以下是我收到的错误：

失败错误域= NSURLErrorDomain代码= -1001“请求超时。”的UserInfo = 0x7fab1ada7d30
      {NSUnderlyingError = 0x7fab1ad7de00“请求超时。”
       NSErrorFailingURLStringKey = http://192.168.0.105/upload2.php，
       NSErrorFailingURLKey = http://192.168.0.105/upload2.php，
       NSLocalizedDescription =请求超时。}

我在服务器上找不到任何问题。有什么建议吗？

为什么AFNetworking NSMutableURLRequest图像上传总是超时？
