我已经从使用正常方式上传图片(当时没有用)切换到使用 MKNetworking 来帮助我完成上传过程，我使用这种方式是因为我发现我得到了更好的错误响应并且它帮助解决了我的问题问题。我收到了一个 NSLog 响应，其中有错误读取

我可以通过 html 表单成功上传图像，所以我确定我的 php.ini 没问题，我允许上传的方式比我要求在我的 iPhone 上上传的更多。

最后但同样重要的是，我的 php

$mysqli = new mysqli($host, $username, $password, $database);
    if ($stmt = $mysqli->prepare("UPDATE `user` SET imagepath=? WHERE email=?")) 
    {
        $stmt->bind_param('ss', $albumname, $email);

    $email = $_POST['email'];
    $uploaddir = 'images/users/';
    $file = basename($_FILES['userfile']['name']);
    $uploadfile = $uploaddir . $file;

    if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {

    }
    $albumname = $uploadfile;
    $stmt->execute();
        $stmt->close(); 
        }


    else {
        printf("Prepared Statement Error: %s\n", $mysqli->error);
    }

$mysqli->close();

我在我的服务器上的 php 日志中没有收到任何错误，

最佳答案

我通过切换到 AFNetwork 解决了我的问题，这是我的新代码

- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    image.image = [info objectForKey:UIImagePickerControllerOriginalImage];
    [self->image setImage:image.image];
    [self  dismissViewControllerAnimated:YES completion:NULL];
    NSURL *url = [NSURL URLWithString:@"http://atmeapp.com"];
    AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
    NSData *imageData = UIImageJPEGRepresentation(image.image, 1);
    NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
                            @"email", [MyClass str],
                            nil];
    NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:@"POST" path:@"/addavatar.php" parameters:params constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
        [formData appendPartWithFileData:imageData name:@"userfile" fileName:[MyClass str] mimeType:@"image/jpeg"];
    }];

    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
    [operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
        NSLog(@"Sent %lld of %lld bytes", totalBytesWritten, totalBytesExpectedToWrite);
    }];
    [httpClient enqueueHTTPRequestOperation:operation];

}

我不确定它为什么起作用，但不管怎样……非常恼火。感谢大家的时间。
