I'm planning to convert my website into an iPhone native application. I'm stuck at the point of how to achieve this.
我打算将我的网站转换为iPhone原生应用程序。我陷入了如何实现这一目标的困境。
Initially, I have developed the first screen i.e., LOGIN screen of my application. My server is built in Java. I'm able to send the login credentials to the server and able to see the request on the server. But I'm unable to receive the response from the server for the request I've sent.
最初,我开发了第一个屏幕,即我的应用程序的LOGIN屏幕。我的服务器是用Java构建的。我能够将登录凭据发送到服务器并能够在服务器上查看请求。但是我无法收到服务器对我发送的请求的响应。
A part of my code is:
我的代码的一部分是:
NSString *post = @"username=";
post = [post stringByAppendingString:username];
post = [post stringByAppendingString:@"&password="];
post = [post stringByAppendingString:password];
NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:@"http://mysite.com/login.action?"]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
// [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];
NSURLConnection *conn=[[NSURLConnection alloc] initWithRequest:request delegate:self];
if (conn)
{
receivedData = [[NSMutableData data] retain];
NSLog(@"In \"LOGIN()\" : receivedData = %@",receivedData);
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
[receivedData setLength:0];
NSLog(@"In \"didReceiveResponse()\" : receivedData = %@",receivedData);
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[receivedData appendData:data];
NSString *ReturnStr = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"In \"didReceiveData()\" : receivedData = %@",receivedData);
NSLog(@"Return String : %@", ReturnStr);
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSLog(@"Succeeded! Received %d bytes of data",[receivedData length]);
NSString *urlData;
if (nil != receivedData) {
urlData = [[[NSString alloc] initWithData:receivedData
encoding:NSUTF8StringEncoding] autorelease];
}
NSLog(@"In \"connectionDidFinishLoading()\" : urlData = %@",urlData);
[receivedData release];
}
- (void)connection:(NSURLConnection *)connection
didFailWithError:(NSError *)error
{
[connection release];
[receivedData release];
NSLog(@"Connection failed! Error - %@ %@",
[error localizedDescription],
[[error userInfo] objectForKey:NSErrorFailingURLStringKey]);
}
- How do I develop a LOGIN application?
- I'm sending a request successfully to the server but I'm unable to get the response from the server. How can I overcome this issue?
如何开发LOGIN应用程序?
我正在向服务器发送请求,但我无法从服务器获得响应。我怎样才能克服这个问题?
