Question

我们一直在为iOS和Android开发应用程序。我们的一个视图使用POST将图片上传到服务器。 Android版本在我们的本地服务器和网站中都可以使用。但是，iOS版本目前只在我们的本地服务器上运行。以下是用于编写POST请求的代码：

NSData * imageData = UIImageJPEGRepresentation（image，1.0）;

    // Create the request.
    NSString* afterURL = [NSString stringWithFormat:@"upload.php?username=%@",username];
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc]
                                    initWithURL:[NSURL URLWithString:
                                                 [NSString stringWithFormat:@"%@%@",url,afterURL]]];
    [request setHTTPMethod:@"POST"];

    //------------------------------------------------------
    // used code from this tutorial: http://www.iriphon.com/2011/11/09/ios-uploading-an-image-from-your-iphone-to-a-server/
    NSString *boundary = @"-----InstantLabor";
    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
    [request addValue:contentType forHTTPHeaderField: @"Content-Type"];

    NSMutableData *body = [NSMutableData data];

    // Now we need to append the different data 'segments'. We first start by adding the boundary.
    [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

    // This line of code came from http://stackoverflow.com/questions/20728317/upload-image-to-the-php-server-from-ios
    //   By creating the string this way instead of the other way, we were able to successfully upload the picture!
    /*
    [body appendData:[[NSString stringWithString:
                       [NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@.jpg\"\r\n", @"dl"]]
                      dataUsingEncoding:NSUTF8StringEncoding]];
     */

     [body appendData:[@"Content-Disposition: form-data; name=\"attachment[userfile]\";filename=\"dl.jpg\"\r\n"
                      dataUsingEncoding:NSUTF8StringEncoding]];


    // We now need to tell the receiver what content type we have
    // In my case it's a png image. If you have a jpg, set it to 'image/jpg'
    [body appendData:[@"Content-Type: image/jpg\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];

    // Now we append the actual image data
    [body appendData:[NSData dataWithData:imageData]];

    // and again the delimiting boundary
    [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

    // adding the body we've created to the request
    [request setHTTPBody:body];
    //-----------------------------------------------------

    // Create url connection and fire request
    _parsedData = nil;
    [NSURLConnection connectionWithRequest:request delegate:self];

当我们试图让它在本地服务器上工作时，上面的代码在我们切换之前不起作用

[body appendData:[@"Content-Disposition: form-data; name=\"attachment[userfile]\";filename=\"dl.jpg\"\r\n"
                  dataUsingEncoding:NSUTF8StringEncoding]];

带

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

即使创建相同的字符串，一个工作，另一个不工作;但是在连接到网站时它们都不起作用。我们尝试的所有东西最终都吐出来了

Undefined index: userfile

回到申请表。由于其中一个有效，我们知道这不是内存问题或特权问题。我们不知道还有什么可能导致这个问题。

提前感谢您的帮助。

经过两天的调整，测试。等我们没有运气解决问题。相反，我们决定合并AFNetworking并按照Upload image from iOS to PHP进行操作，以使我们的图片上传工作。

PHP图片上传适用于localhost但不适用于GoDaddy服务器
