ASIFormDataRequest上传空白图像

Question

在这里使用ASIFormDataRequest搜索一个简单的图像上传之后，我终于让它正常工作了(有点)，但是出现了一个意外的错误。

我的图像被上传到我的服务器上，但它是空白，大小为0字节。这是我的代码：

 -(IBAction)uploadImage:(id)sender
{
    NSData *data = UIImageJPEGRepresentation(self.imageView.image,0.6f);
    NSString *file = [NSTemporaryDirectory() stringByAppendingPathComponent:@"upload.png"];
    [data writeToFile:file atomically:YES];

    NSString *strURL = @"http://domain.com/upload.php";

    ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:strURL]];
    UIImage *image1=[UIImage imageNamed:file];
    NSData *imageData1=UIImageJPEGRepresentation(image1, 1.0);
    [request setData:imageData1 withFileName:file andContentType:@"image/jpeg" forKey:@"avatar"];
    [request setRequestMethod:@"POST"];
    //[request appendPostData:body];
    [request setDelegate:self];
    [request setTimeOutSeconds:13.0];
    request.shouldAttemptPersistentConnection = NO;
    [request setDidFinishSelector:@selector(uploadRequestFinished:)];
    [request setDidFailSelector:@selector(uploadRequestFailed:)];
    [request startAsynchronous];
}
- (void)uploadRequestFinished:(ASIHTTPRequest *)request
{
    NSLog(@" Error - Statistics file upload ok: \"%@\"",[request responseString]);
}

- (void)uploadRequestFailed:(ASIHTTPRequest *)request{
    NSLog(@" Error - Statistics file upload failed: \"%@\"",[[request error] localizedDescription]);

}

我的PHP代码：

<?php 

 $target = "./"; 
 $target = $target . basename( $_FILES['avatar']['name']) ; 
 $ok=1; 
 if(move_uploaded_file($_FILES['avatar']['tmp_name'], $target)) 
 {
 echo "The file ok";
 } 
 else {
 echo "Sorry, there was a problem uploading your file.";
 }

?>

起初，我认为这是一个文件夹过滤的事情，但我用一个简单的html表单上传(使用相同的php文件，未经编辑)来测试它，该文件是完全上传的。

我知道这种上传文件的方法是危险的，但就目前而言，这是我唯一能得到的东西。

知道为什么我的文件没被上传吗？谢谢。

好的，我遵循了您的建议，实际上使用了AFNetwork，这是我帮助他人的代码。

    NSData *imageToUpload = UIImageJPEGRepresentation(_imageView.image, 0.5f);
    AFHTTPClient *client= [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"http://domain.com"]];

    NSMutableURLRequest *request = [client multipartFormRequestWithMethod:@"POST" path:@"upload.php" parameters:nil constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
        [formData appendPartWithFileData: imageToUpload name:@"avatar" fileName:fullFilename mimeType:@"image/jpeg"];
    }];

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

    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSString *response = [operation responseString];
        NSLog(@"response: [%@]",response);
        [MBProgressHUD hideHUDForView:self.view animated:YES];

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        if([operation.response statusCode] == 403){
            NSLog(@"Upload Failed");
            return;
        }
        NSLog(@"error: %@", [operation error]);

    }];

    [operation start];
