我刚把我的iOS应用程序放在连接到我的无线网络的iPad上,我无法连接到网络服务。这是在模拟器中工作,但是当我把它放在iPad上时,连接超时。放在真实设备上时是否需要不同的东西?
不过这是我的代码:
-(BOOL)Webservice{
recordResults = FALSE;
user = nameInput.text;
pass = passwordInput.text;
NSString *soapMessage = [NSString stringWithFormat:
@"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
"<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n"
"<soap:Body>\n"
"<ValidateUser xmlns=\"http://tempuri.org/\">\n"
"<User>%@</User>\n"
"<Password>%@</Password>\n"
"</ValidateUser>\n"
"</soap:Body>\n"
"</soap:Envelope>\n", nameInput.text, passwordInput.text
];
NSLog(soapMessage);
NSURL *url = [NSURL URLWithString:@"http://192.168.51.3:60010/Webservice/IDLMobile.asmx?WSDL"];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
[theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue: @"http://tempuri.org/ValidateUser" forHTTPHeaderField:@"soapAction"];
[theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
[theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if( theConnection )
{
webData = [[NSMutableData data] retain];
}
else
{
NSLog(@"theConnection is NULL");
}
[nameInput resignFirstResponder];
[passwordInput resignFirstResponder];
/* update function */
}
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
[webData setLength: 0];
}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[webData appendData:data];
}
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
NSLog(@"ERROR with theConenction");
[connection release];
[webData release];
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSLog(@"DONE. Received Bytes: %d", [webData length]);
NSString *theXML = [[NSString alloc] initWithBytes: [webData mutableBytes] length: [webData length] encoding:NSUTF8StringEncoding];
NSLog(theXML);
[theXML release];
if( xmlParser )
{
[xmlParser release];
}
xmlParser = [[NSXMLParser alloc] initWithData: webData];
[xmlParser setDelegate: self];
[xmlParser setShouldResolveExternalEntities: YES];
[xmlParser parse];
[connection release];
[webData release];
}
-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *)qName
attributes: (NSDictionary *)attributeDict
{
if ([elementName isEqualToString:@"Message"])
{
//---displays the country---
NSLog(soapResults);
NSString *convertString = soapResults;
// check = 0;
check = [convertString intValue];
thyCheck = [convertString intValue];
NSLog(@"user is");
// NSLog(user);
if(check > 0){
[self someUpdateFunction];
NSString *string = [NSString stringWithFormat:@"%d", check];
NSLog(string);
NSLog(@"lolololol");
check = 0;
}else{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Problem!" message:@"Incorrect Username or Password"
delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:@"Yes", nil];
[alert show];
[alert release];
thyCheck = 0;
}
// gotoContent = checkConfirm;
}
if( [elementName isEqualToString:@"ValidateUserResponse"])
{
if(!soapResults)
{
soapResults = [[NSMutableString alloc] init];
NSLog(soapResults);
NSLog(@"above is soap validate user");
}
recordResults = TRUE;
}
}
-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
if( recordResults )
{
[soapResults appendString: string];
}
}
我能想到的另一件事是iPhone必须连接到3G网络吗?所以它无法通过与路由器的连接访问Web服务?
答案 0 :(得分:3)
192.168.51.3看起来像一个网络的私有子网,可能是你的WiFi在另一个子网上?
