将图像数据（NSData）发送到服务器 [英] Sending an image data(NSData) to the server

问题描述

我想将图像数据发送到服务器，为此，我已将该数据附加到请求的HTTP主体并发送它。我使用以下代码。

I want to send image data to the server, For that, I have appended that data to the HTTP body of the request and sent it. I am using the following code.

NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:@"http://developers.our-works.com/forms/TestReceiver.aspx"]];
[request setHTTPMethod:@"POST"];

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

// now lets create the body of the post 
NSMutableData *body = [NSMutableData data];

[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];    
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@\"\r\n",tempFileName] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imgdata]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

//data into the string..... verifying............
NSString *strTest = [[NSString alloc] initWithData:body encoding:NSUTF8StringEncoding];
NSLog(@"%@",strTest);

// setting the body of the post to the request
[request setHTTPBody:body];

// now lets make the connection to the web
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

现在我必须发送两个不同图像的NSData。所以，只想问一下，我可以在同一个体内发送这两个不同的图像的NSData。
或者，我必须为其他图像的数据编写相同的代码。

Now I have to send the NSData of the two different images. So, just want to ask that, can I send those two different image's NSData within the same body as above. Or, I have to code the same thing for the other image's Data.

请帮助我解决这个问题。谢谢你。

Please, help me out of this. Thanking you.

推荐答案

如果服务器需要两个图像，你必须为其他数据编码相同的东西
这取决于web service.you可以从以下链接中获取想法：

You have to code same thing for other data if server needs two images together It depends on web service.you can take idea from following link:
