iPhone：将图片上传到网页aspx文件 [英] iPhone : upload image to web aspx file

问题描述

我有一个小问题。
我必须使用POST方法将iPhone上的照片上传到网络服务器，但服务器文件在aspx中。
我用我的服务器和PHP文件尝试了我的代码：效果很好！
现在使用aspx文件：不会上传：（b / b）

我没有对.aspx的访问权。

这里是我的iphone代码：

  NSData * imageData = UIImageJPEGRepresentation（imageView.image，70）; 
 
 NSString * urlString = @http://iphone.domain.net/upload_photos.aspx; 
 
 
 NSMutableURLRequest * request = [[[[[NSMutableURLRequest alloc] init] autorelease]; 
 [request setURL：[NSURL URLWithString：urlString]]; 
 [request setHTTPMethod：@POST]; 
 
 NSString * boundary = [NSString stringWithString ：@--------------------------- 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\\\
，boundary] dataUsingEncoding：NSUTF8StringEncoding]]; 
 [body ap pendData：[[NSString stringWithFormat：@Content-Disposition：form-data;名称= \ photo\;文件名= \％@。jpg \\r\\\
，[c nom]] dataUsingEncoding：NSUTF8StringEncoding]]; 
 [body appendData：[[NSString stringWithString：@Content-Type：应用/ octet-stream \r\\\
\r\\\
] dataUsingEncoding：NSUTF8StringEncoding]]; 
 [body appendData：[NSData dataWithData：imageData]]; 
 [body appendData：[ [NSString stringWithFormat：@\r\\\
  - ％@  -  \r\\\
，boundary] dataUsingEncoding：NSUTF8StringEncoding]]; 
 [request setHTTPBody：body]; 
  

我认为问题来自Content-Type或我的dataUsingEncoding：参数
你有没有想法解决方案如果你不反对使用第三方库，可以考虑看看ASIHttpRequest。你的生活变得如此简单：

  ASIFormDataRequest * request = [ASIFormDataRequest requestWithURL：url]; 
 
 //在磁盘上传文件
 [请求setFile：@/ Users / ben / Desktop / ben.jpgwithFileName：@myphoto.jpgandContentType：@image / jpeg
 forKey：@photo]; 
 
 //上传一个NSData实例
 [请求setData：imageData withFileName：@myphoto.jpgandContentType：@image / jpegforKey：@photo]; 
  

I have a little problem. I have to upload a photo from my iPhone to a web server with POST Method but the server file is in aspx. I tried my code with my server and PHP file : works well ! Now with aspx file : doesn't upload :(

I don't havec access to the .aspx .

Here is my iphone code :

NSData *imageData = UIImageJPEGRepresentation(imageView.image,70);

NSString *urlString = @"http://iphone.domain.net/upload_photos.aspx";


NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];

NSString *boundary = [NSString stringWithString:@"---------------------------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",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"photo\"; filename=\"%@.jpg\"\r\n",[c nom]] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"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]];
[request setHTTPBody:body];

I think the problem comes from the Content-Type or for my dataUsingEncoding: parameter. Have you got and idea to solve it?

解决方案

If you're not opposed to using a 3rd party library consider looking at ASIHttpRequest. It'll make your life so much easier:

http://allseeing-i.com/ASIHTTPRequest/How-to-use

  ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];

    // Upload a file on disk
    [request setFile:@"/Users/ben/Desktop/ben.jpg" withFileName:@"myphoto.jpg" andContentType:@"image/jpeg"
    forKey:@"photo"];

    // Upload an NSData instance
    [request setData:imageData withFileName:@"myphoto.jpg" andContentType:@"image/jpeg" forKey:@"photo"];
