IOS：将图像上传到服务器Php从ios设备不工作？

Question

我用这个代码的设备：

NSURL *url = [NSURL URLWithString:@"http://localhost/phd-admin//testing.php"]; 

    NSData *imageData=[NSData dataWithContentsOfURL:url]; 
    ; 
    NSLog(@"data length %d",[imageData length]); 
    // UIImage *img = [UIImage imageWithData:[NSData dataWithContentsOfURL:url]]; 

    if (imageData != nil) 
    { 
    NSString *filenames = [NSString stringWithFormat:@"Deal.png"];  //set name here 
     NSLog(@"%@", filenames); 
     NSString *urlString = @"http://localhost/php-admin//receiveFile.php"; 

     NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; 

     [request setURL:[NSURL URLWithString:urlString]]; 
     [request setHTTPMethod:@"POST"]; 

     NSString *boundary = @"---------------------------14737809831466499882746641449"; 
     NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; 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:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"filenames\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
     [body appendData:[filenames dataUsingEncoding:NSUTF8StringEncoding]]; 

     [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
     [body appendData:[@"Content-Disposition: form-data; name=\"userfile\"; filename=\"Deal.png" 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]]; 
     // setting the body of the post to the reqeust 
     [request setHTTPBody:body]; 
     // now lets make the connection to the web 
     NSLog(@"requereting %@",request); 
     NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; 
     NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; 
     NSLog(returnString); 
      NSLog(@"response %@",returnString); 
     NSLog(@"finish"); 

我用这个代码用于服务器端：

<?php 
$myparam = $_POST['userfile'];  //getting image Here 
$mytextLabel= $_POST['filenames'] ; //getting textLabe Here 
echo $myparam; 
echo $mytextLabel; 
$target_path = "upload/"; 
$target_path = $target_path . basename($_FILES['myfile']['name']); 
if(move_uploaded_file($_FILES['myfile']['tmp_name'], $target_path)) { 
    echo "The file ". basename($_FILES['myfile']['name']) . " has been uploaded"; 
} else { 
    echo "There was an error uploading the file, please try again!".$myparam."val".$mytextLabel; 
} 
?> 

，但它不工作？

请提出您的答案。 谢谢，s。

我相信你有太多的线路，并不需要这一切。尝试只是这不是所有的appendData：

[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@\"\r\n", filenames] 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]]; 

你PHP：

<?php 
    $file = $_FILES['userfile']; 
    $target_path = "upload/" . $label; 

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

尝试这种方式。
