【问题描述】:
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,为什么会调用失败块?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。
目标 - C:
- (void)upload {
NSString *fileName = [NSString stringWithFormat:@"%ld%c%c.jpg", (long)[[NSDate date] timeIntervalSince1970], arc4random_uniform(26) + 'a', arc4random_uniform(26) + 'a'];
NSString *imagePath = [[NSBundle mainBundle] pathForResource:@"image" ofType:@"jpg"];
NSData *data = UIImagePNGRepresentation([UIImage imageWithContentsOfFile:imagePath]);
NSString *URLString = @"http://myServer/myAppFolder";
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager manager] initWithBaseURL:[NSURL URLWithString:URLString]];
AFJSONResponseSerializer *responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments];
[manager setResponseSerializer:responseSerializer];
[manager.responseSerializer setAcceptableContentTypes:[NSSet setWithObject:@"text/html"]];
AFHTTPRequestOperation *operation = [manager POST:@"upload.php" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:data name:@"uploadedfile" fileName:fileName mimeType:@"image/jpeg"];
} 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...");
}];
}
上传.php:
<?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!";
}
?>;
我收到此错误:
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;
【问题讨论】:
-
不是 ios 编码器,但您的
The file ...消息中的“字符 0 周围的值无效”表明 cocoa 期待一些您未发送的其他文本。 -
你为什么使用
AFJSONResponseSerializer?您的 PHP 没有返回 JSON...尝试使用[AFResponseSerializer serializer]... -
我试图在我的 .php 文件中回显由 json_encode 生成的 JSON。但是最后有一个关于垃圾的错误。我意识到在序列化程序中可能会出现问题,尽管不知道 AFHTTPResponseSerializer 这实际上是一个答案。感谢 rokjarc 为我定罪!也感谢 Marc 的回答:-)
-
不客气。我看到你在我输入答案时解决了这个问题:)
-
确实是 rokjarc :-) 干杯!
