在我的iPhone項目中,我需要將成員ID和密碼傳遞給Web服務器。我試過我的代碼與同步以及異步請求,但我總是得到錯誤:連接失敗:錯誤的URL(空)。任何人都可以幫我找到代碼有問題嗎?連接失敗:將POST數據從Xcode發送到傳統ASP頁時發生錯誤Url(空)錯誤。
我的代碼:
NSString *post =[NSString stringWithFormat:@"memberId=%@&pwd=%@",txtUName.text,txtPwd.text];
NSLog(@"%@",post);
NSURL *url = [NSURL
URLWithString:@"http://testweb.talkfusion.com/videocenter/xlogin.asp%@"];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding
allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
//set up the request to the website
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];
NSError *error;
NSURLResponse *response;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *data=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
NSLog(@"%@",data);
NSLog(@"Connection failed! Error - %@ %@",
[error localizedDescription],
[[error userInfo] objectForKey:NSURLErrorFailingURLStringErrorKey]);
我從網址中刪除了%@,它工作正常。謝謝。 – user973637
