iPhone SDK：多張圖片上傳到服務器的SOAP請求

Question

我很清楚地知道，你可以指望這個線程的重複，只是因爲多次這個問題被要求以不同的方式。我沒有從這個論壇上的現有問題中找到任何解決方案，因此我將創建一個新線程。

在這裏，我有一個代碼，在一次上傳多張圖片。所以，請記下「多個圖片上傳」的句子。

我要上傳1倍或2或3或4的圖像與一些文本參數和我面對的是「相同的圖像上傳多次」指的是具有對服務器多次單個圖像的問題一起。

例子：

NSString *urlString = [NSString stringWithFormat:@"%@/MultipleImageUpload",soapAction]; 
NSMutableURLRequest *theRequest = [[NSMutableURLRequest alloc] init]; 
[theRequest setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData]; 
[theRequest setHTTPShouldHandleCookies:NO]; 
[theRequest setTimeoutInterval:60]; 
[theRequest setURL:[NSURL URLWithString:urlString]]; 
[theRequest setHTTPMethod:@"POST"]; 

NSMutableData *body = [NSMutableData data]; 
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",BOUNDARY_MULTIPART_IMAGE]; 
[theRequest addValue:contentType forHTTPHeaderField: @"Content-Type"]; 

//parameter SecurityCode 
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", BOUNDARY_MULTIPART_IMAGE] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"SecurityCode\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[SEC_CODE dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 

//parameter LoggedInUserID 
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", BOUNDARY_MULTIPART_IMAGE] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"LoggedInUserID\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[@「23433」 dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 

//parameter Device 
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", BOUNDARY_MULTIPART_IMAGE] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"Device\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[@「iPhone」 dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 

for (int i=0; i<[arrImgs count]; i++) { 
    UIImage* image = [arrImgs objectAtIndex:i]; 
    NSData *imgData = UIImageJPEGRepresentation(image, 1.0); 
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", BOUNDARY_MULTIPART_IMAGE] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"product_photo\"; filename=\"%d.jpg\"\r\n", i] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[@"Content-Type: image/jpeg\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[NSData dataWithData:imgData]]; 
    [body appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
} 

// close form 
[body appendData:[[NSString stringWithFormat:@"--%@--\r\n", BOUNDARY_MULTIPART_IMAGE] dataUsingEncoding:NSUTF8StringEncoding]]; 

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

請讓我知道如果任何人有這個問題的解決..

感謝，

對不起每個人， 但我得到的解決方案。實際上，我必須在下面的行中設置動態文件名。我必須將「product_photo」設置爲具有像「product_photo1」或「product_photo2」等隨機數的動態字符串等。

for (int i=0; i<[arrImgs count]; i++) 
{ 
    UIImage* image = [arrImgs objectAtIndex:i]; 
    NSData *imgData = UIImagePNGRepresentation(image); 
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", BOUNDARY_MULTIPART_IMAGE] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"product_photo%d\"; filename=\"%d.png\"\r\n", i,i] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[@"Content-Type: image/png\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:imgData]; 
    [body appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
}
