php - 尽管上传成功，但调用了 AFNetworking 2.0 POST + PHP 阻止失败
<p><p>我的问题的描述实际上是有问题的标题。我是网络技术的新手，所以这种行为对我来说有点引人注目。图片上传成功，为什么会调用失败 block ？此外，我在 SoF 上搜索了我的问题的答案并应用了一些解决方案，但仍然出现此错误。如果可能，请提供帮助。提前谢谢你。</p>
<p>目标 - C:</p>
<pre><code>- (void)upload {
NSString *fileName = timeIntervalSince1970], arc4random_uniform(26) + 'a', arc4random_uniform(26) + 'a'];
NSString *imagePath = [ pathForResource:@"image" ofType:@"jpg"];
NSData *data = UIImagePNGRepresentation();
NSString *URLString = @"http://myServer/myAppFolder";
AFHTTPRequestOperationManager *manager = [ initWithBaseURL:];
AFJSONResponseSerializer *responseSerializer = ;
;
];
AFHTTPRequestOperation *operation = [manager POST:@"upload.php" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
;
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"Success %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Failure / %@, /%@", error, operation.responseString); //error comes from here
}];
[operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
NSLog(@"uploading...");
}];
}
</code></pre>
<p>上传.php:</p>
<pre><code><?php
$filename="uploaded";
$target_path = "uploads/";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
echo "The file ".basename( $_FILES['uploadedfile']['name'])." has been uploaded";
} else {
echo "There was an error uploading the file, please try again!";
}
?>;
</code></pre>
<p>我收到此错误:</p>
<pre><code>Failure / Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (Invalid value around character 0.) UserInfo=0x8a633e0 {NSDebugDescription=Invalid value around character 0.}, /The file 1389046572lb.jpg has been uploaded;
</code></pre></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>问题似乎在于您使用 <code>AFJSONResponseSerializer</code> 来序列化 PHP 上传脚本的响应。</p>
<p>而且您的 PHP 没有返回 JSON - 因此序列化程序会引发错误。</p>
<p>您可以修改 PHP 脚本，使其返回 JSON 格式的结果。或者您可以使用不同类型的序列化程序。</p>
<p>根据<a href="https://github.com/AFNetworking/AFNetworking/issues/1387" rel="noreferrer noopener nofollow">this forum</a>解决方案是使用 <code></code> - 我不确定它是否存在。尝试基本的 <code>AFHTTPResponseSerializer</code>。</p></p>
