网络服务方法:
-(void)ServiceCall:(NSString*)ServiceName :(NSString *)DataString
{
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
[sessionConfiguration setAllowsCellularAccess:YES];
[sessionConfiguration setHTTPAdditionalHeaders:@{ @"Accept" : @"application/json" }];
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration];
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@",ServiceURL]];
NSLog(@"URl %@%@",url,DataString);
// Configure the Request
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setValue:[NSString stringWithFormat:@"%@=%@", strSessName, strSessVal] forHTTPHeaderField:@"Cookie"];
request.HTTPBody = [DataString dataUsingEncoding:NSUTF8StringEncoding];
request.HTTPMethod = @"Post";
// post the request and handle response
NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)
{
// Handle the Response
if(error)
{
NSLog(@"%@",[NSString stringWithFormat:@"Connection failed: %@", [error description]]);
// Update the View
dispatch_async(dispatch_get_main_queue(), ^{
// Hide the Loader
[MBProgressHUD hideHUDForView:[[UIApplication sharedApplication] delegate].window animated:YES];
});
return;
}
NSArray * cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL:request.URL];
for (NSHTTPCookie * cookie in cookies)
{
NSLog(@"%@=%@", cookie.name, cookie.value);
strSessName=cookie.name;
strSessVal=cookie.value;
}
NSString *retVal = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
}];
[postDataTask resume];
}
该服务运行良好的Xcode早期版本和iOS以前的版本，但当我更新到Xcode 7.0，在iOS 9.0上，它开始给我的问题如下，当我调用上面的web服务方法。我得到的日志错误是:
Connection failed: ErrorDomain =NSURLErrorDomain Code=-1022 由于应用程序传输安全策略，资源无法加载 需要使用安全连接。” 用户信息= {NSUnderlyingError = 0 x7fada0f31880{错误 Domain=kCFErrorDomainCFNetwork Code=-1022 "(null)"}, NSErrorFailingURLStringKey = # EYZ0, NSErrorFailingURLKey = # EYZ0, NSLocalizedDescription=资源无法加载 应用程序传输安全策略要求使用安全 连接。}< / p >
我已经尝试了以下问题和答案，但没有得到任何结果，有任何提前的想法，我可以如何删除服务呼叫错误?
