任何人都可以提供一些链接或示例，使用
iphone API将文件上传到HTTP服务器。

在此先感谢，

解决方案

下面的代码使用HTTP POST将NSData发布到Web服务器。您还需要PHP的小知识。

  NSString * urlString = @http://yourserver.com/upload.php ; 
 NSString * filename = @filename; 
 request = [[[[NSMutableURLRequest alloc] init] autorelease]; 
 [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 * postbody = [NSMutableData data]; 
 [postbody appendData：[[NSString stringWithFormat：@\r\\\
  - ％@ \r\\\
，boundary] dataUsingEncoding：NSUTF8StringEncoding]]; 
 [postbody appendData：[[NSString stringWithFormat：@Content-Disposition：form-data; name = \userfile \; filename = \％@。jpg \\r\ n，filename] dataUsingEncoding：NSUTF8StringEncoding]]; 
 [postbody appendData：[[NSString stringWithString：@Content-Type：application / octet-stream\r\\\
\r\\\
] dataUsingEncoding：NSUTF8StringEncoding]]; 
 [postbody appendData：[NSData dataWithData：YOUR_NSDATA_HERE]]; 
 [postbody appendData：[[NSString stringWithFormat：@\r\\\
  - ％@  -  \r\\\
，boundary] dataUsingEncoding：NSUTF8StringEncoding]]; 
 [request setHTTPBody：postbody]; 
 
 NSData * returnData = [NSURLConnection sendSynchronousRequest：request returningResponse：nil error：nil]; 
 returnString = [[NSString alloc] initWithData：returnData encoding：NSUTF8StringEncoding]; 
 NSLog（@％@，returnString）; 
  

Can anyone provide me some links or examples to upload files to the HTTP server using iphone APIs.

Thanks in Advance, BP

The code below uses HTTP POST to post NSData to a webserver. You also need minor knowledge of PHP.

NSString *urlString = @"http://yourserver.com/upload.php";
NSString *filename = @"filename";
request= [[[NSMutableURLRequest alloc] init] autorelease];
[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 *postbody = [NSMutableData data];
[postbody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@.jpg\"\r\n", filename] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[NSData dataWithData:YOUR_NSDATA_HERE]];
[postbody appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:postbody];

NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(@"%@", returnString);
