如何發佈到Web服務

Question

在我的項目的圖像： -

1）點擊從相機拍攝照片（不要保存）。

2）顯示裁剪圖像，2個按鈕，併發布後cancel.where按鈕後的圖像和取消按鈕放棄image.it看起來是這樣的。

我不知道如何發佈相機捕獲圖像。我通過互聯網搜索發現了很多代碼，但沒有找到任何代碼可以幫助我。

我想這些鏈接給代碼..

First，Second，Third，等等。

我希望有人會help..how張貼？謝謝。

-(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]; 
}

Answer 1

UPDATE：

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

這裏您的存儲數據庫字段名的圖像picture然後name參數寫的字段名稱。 ..

使用此代碼...

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類此

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];
