Php 图像上传iOS

几个小时以来，我一直在尝试将jpg图像上传到我的服务器上。我找到了很多关于这个话题的问题和解决方案，但我没有找到答案。 到目前为止，我得到的是：

XCODE:

 - (void) upload {
UIImage *img = [UIImage imageNamed:@"test.jpg"];

NSData *imageData = UIImageJPEGRepresentation(img ,90);
long imageSize = (long)[imageData length];
NSLog(@"SIZE OF IMAGE: %.2f Mb", (float)imageSize/1024/1024);


NSString *urlString = @"http://www.MYURL.com/upload.php";

NSMutableURLRequest *request = [[NSMutableURLRequest alloc]init];
[request setURL:[NSURL URLWithString:urlString]] ;
[request setHTTPMethod:@"POST"];

NSString *boundary = @"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:@"boundary=%@",boundary];
[request addValue:contentType forHTTPHeaderField:@"Content-Type"];

NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary]dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Disposition: form-data; name=\"userfile\"; filename=\".jpg\"\r\n"dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Type: application/octet-stream\r\n\r\n"dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n", boundary]dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:body];

NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];

NSLog(@"%@data",returnString);
}

PHP:

我对服务器上的目录设置了完全权限，这样就不会出现错误

帮我解决这个问题会让我非常幸运

您在文件

NSLog

中得到了什么？您的服务器日志中是否有任何内容？为什么不向sendSynchronousRequest传递一个N错误，然后检查结果？PHP服务器端代码在哪里，

filename=\”.jpg\“

？？我认为HTTP内容类型头应该是“多部分/混合”；boundary=“…””可能是您的问题的一部分。您可能还需要将正文部分内容类型设置为image/jpeg。在任何情况下，同时给我们返回的NSError和server返回字符串都会有很大帮助。我应该在哪里设置“multipart/mixed”？like->NSString*contentType=[NSString stringWithFormat:@“多部分/混合；边界=%@”，边界]；

<?php
$target_path = "./";

$target_path = $target_path . basename( $_FILES['picture']['name']);  

if(move_uploaded_file($_FILES['picture']['tmp_name'], $target_path)) {  
echo "The file ".  basename( $_FILES['picture']['name'])." has been uploaded";  
} else{  
echo "There was an error uploading the file, please try again!";  
}
?>
