使用MKNetworking图像上传PHP获取内部错误500

Question

我已经从使用正常的方式上传图像（Didnt可以正常工作）切换为使用MKNetworking来协助我进行上传过程，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帮助解决了我的问题。 我收到一个NSLog响应，并显示错误消息

我可以通过html表单成功上传图像，因此可以确定我的php.ini很好，并且可以上传的方式比我要在iPhone上上传的方式要多。

最后但并非最不重要的是，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();

我在服务器上的php日志中没有收到任何错误，

Answer 1

看起来基本正确，我只是在php中上传了MkNetworkKit /图像。 我在这里发现的唯一错误的地方是线路

[NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   @"email", [MyClass str]

您可能要切换@“ email”和[MyClass str]，使用dictionaryWithObjectsAndKeys时，值应位于key之前。

这是我的实现（在MKNetworkEngine的子类中）：

-(MKNetworkOperation*) uploadImage:(UIImage*)image onSuccess:(EmptyBlock)successBlock onError:(MKNKErrorBlock)errorBlock {
    NSMutableDictionary *params = [[NSDictionary dictionary]mutableCopy];
    [params setValue:@"[YOUR_VALUE]" forKey:@"[YOUR_KEY]"];
    MKNetworkOperation *op = [self operationWithPath:@"[YOUR_PATH]" params:params httpMethod:@"POST"];
    [op addData:UIImageJPEGRepresentation(image, 0.5) forKey:@"userfile" mimeType:@"image/jpeg" fileName:@"[YOUR_FILENAME]"];

    [op onCompletion:^(MKNetworkOperation *completedOperation) {
    if(successBlock) {
        successBlock();
    }
    } onError:^(NSError *error) {

        TFLog(@"RCNetworkEngine.uploadError:%@, error:%@", url, [error localizedDescription]);
        if(errorBlock)
            errorBlock(error);
    }];
    [self enqueueOperation:op];
    return op;
}

Answer 2

我通过切换到AFNetwork继承了我的新代码，从而解决了我的问题

- (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];

}

我不确定为什么它起作用，但是无论如何……非常恼火。 谢谢大家的时间。
