如何将图像上传到iPhone的远程服务器？ [英] How to upload image to remote server in iphone?

问题描述

我正在尝试上传一张我在相机帮助下点击的图片。我正在尝试以下代码将图像上传到远程服务器。

I am trying to upload a image which i am clicking with the help of the camera. I am trying the following code to upload the image to the remote server.

-(void)searchAction:(UIImage*)theImage
{
    UIDevice *dev = [UIDevice currentDevice];
    NSString *uniqueId = dev.uniqueIdentifier;

    NSData * imageData = UIImagePNGRepresentation(theImage);

    NSString *postLength = [NSString stringWithFormat:@"%d",[imageData length]];

    NSString *urlString = [@"http://www.amolconsultants.com/im.jsp?" stringByAppendingString:@"imagedata=iPhoneV0&mcid="];
    urlString = [urlString stringByAppendingString:uniqueId];
    urlString = [urlString stringByAppendingString:@"&lang=en_US.UTF-8"];

    NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
    [request setURL:[NSURL URLWithString:urlString]];
    [request setHTTPMethod:@"POST"];
    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
    [request setHTTPBody:imageData];

    NSURLConnection *conn=[[NSURLConnection alloc] initWithRequest:request delegate:self];
    if (conn == nil) 
    {
        NSLog(@"Failed to create the connection");
    }
}

但没有任何内容发布。控制台窗口中也没有任何内容。我在动作表中调用此方法。当用户点击操作表的第一个按钮时，会调用此方法发布图像。

But nothing is getting posted. Nothing comes in the console window also. I am calling this method in the action sheet. When the user clicks on the 1st button of the action sheet this method is called to post the image.

任何人都可以帮我这个...

推荐答案

您可以使用第三方的库 asi-http-request 。它简化了大部分的努力工作。在您的情况下，您只需执行以下操作：

You can use the libraries from a third party called asi-http-request. It simplyfies for you most of the hard works. In your case, you just do as the following:

ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request appendPostData:imageData];
[request setRequestMethod:@"PUT"];
