如何发布到Web服务

Question

在我的项目的图像： -

1）点击从相机拍摄照片（不要保存）。

2）显示裁剪图像，2个按钮，并发布后cancel.where按钮后的图像和取消按钮放弃image.it看起来是这样的。

我不知道如何发布相机捕获图像。我通过互联网搜索发现了很多代码，但没有找到任何代码可以帮助我。

我想这些链接给代码..

First，Second，Third，等等。

我希望有人会help..how张贴？谢谢。

-(IBAction)sendRequest:(id)sender { 

    #define DataDownloaderRunMode @"myapp.run_mode" 

     NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url 
             cachePolicy:NSURLRequestUseProtocolCachePolicy 
             timeoutInterval:60]; 

     [request setHTTPMethod:@"POST"]; 

     NSString *boundary = @"----WebKitFormBoundarycC4YiaUFwM44F6rT"; 

     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--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 

     [body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name="attachment[file]"; 
     filename="picture.png"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 

     [body appendData:[[NSString stringWithString:@"Content-Type: image/png\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]; 

     NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request 
                   delegate:self 
                   startImmediately:NO]; 

     [connection scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:DataDownloaderRunMode]; 

     [connection start]; 
} 

和连接此张贴..按钮

Answer 1

UPDATE：

[body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"picture\"; filename=\"picture.png\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 

这里您的存储数据库字段名的图像picture然后name参数写的字段名称。 ..

使用此代码...

Answer 2

// add image data 
NSData *imageData = UIImageJPEGRepresentation(imageToPost, 1.0); 
if (imageData) { 
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"image.jpg\"\r\n", FileParamConstant] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithString:@"Content-Type: image/jpeg\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:imageData]; 
    [body appendData:[[NSString stringWithFormat:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
}

或者你可以使用ASIHTTP类此

ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:@"http://URL/Service.asmx/RegisterClient?"]]; 
      request.delegate=self; 

      encodedImage = UIImagePNGRepresentation(imgRef); 

      [[NSUserDefaults standardUserDefaults]setObject:UIImagePNGRepresentation(imgRef) forKey:@"userImage"]; 

      str =[Base64 encode:encodedImage]; 

      [request setPostValue:email.text forKey:@"Email"]; 

      [request setPostValue:name.text forKey:@"FName"]; 
      [request setPostValue:str forKey:@"UserImage"]; 
      [request setPostValue:dob.text forKey:@"dob"]; 
      [request setPostValue:phoneNumber.text forKey:@"Phone"]; 
      [request setPostValue:ggg.text forKey:@"Gender"]; 
      [request setPostValue:address.text forKey:@"Address"]; 
      [request setPostValue:interest.text forKey:@"Interest"]; 

      [request startAsynchronous];
