[英]Getting Error Domain=NSURLErrorDomain Code=-1004 “Could not connect to the server.”
我使用NSURLConnection从我的ios应用程序调用Web服务。 这是我的代码
#define kBaseServerUrl @"http://winshark.softwaytechnologies.com/bariodwcfservice/baroidservice.svc/Json/"
#define kProductServiceUrl @"Products"
-(void)callService{
NSURL *url;
if (currState == ProductServiceState) {
url = [NSURL URLWithString:[NSString stringWithFormat:@"%@%@/%d",kBaseServerUrl,kProductServiceUrl,[self getRevisionNumberForProduct]]];
}
else if(currState == TankStrickerServiceState){
url = [NSURL URLWithString:[NSString stringWithFormat:@"%@%@/%d",kBaseServerUrl,kTankStrickerServiceUrl,[self getRevisionNumberForTankStricker]]];
}else if(currState == CalculationServiceState){
url = [NSURL URLWithString:[NSString stringWithFormat:@"%@%@/%d",kBaseServerUrl,kCalculationServiceUrl,[self getRevisionNumberForCalculation]]];
}else{
//Future Use
}
NSLog(@"%@",[url absoluteString]);
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
NSURLConnection *urlConnection = [[NSURLConnection alloc] initWithRequest:urlRequest delegate:self];
NSLog(@"%@",urlConnection);
}
它最终称这个网址为http://winshark.softwaytechnologies.com/bariodwcfservice/baroidservice.svc/Json/Products/123
但是当我在浏览器中点击这个网址它工作正常,但在我的应用程序中我得到这个错误
Error Domain=NSURLErrorDomain Code=-1004 "Could not connect to the server."
请帮我解决可能存在的问题
看起来你正确的设置,我怀疑你的对象有什么 - 尝试通过用以下内容替换现有的URL请求来调用硬编码的URL:
NSURLRequest *urlRequest = [NSURLRequest
requestWithURL:[NSURL URLWithString:@"http://www.google.com"]];
应该更容易进行故障排除。
