通过SSL请求Web服务

问题描述

我正在努力使用https请求Web服务。我收到这种错误：

i am struggling to request web service using https. I am getting this kind of error:

An error occured : The certificate for this server is invalid. You might be connecting to a server that is pretending to be "SERVER_ADDRESS" which could put your confidential information at risk.

我没有使用NSUrlConnectionDelegate。这是我的方法：

I am not using NSUrlConnectionDelegate. Here is my method:

- (void)sendRequestWithUrl:(NSURL*)url block:(void (^)(NSDictionary *dict, NSError *error)) block{
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
    [request setHTTPMethod:@"POST"];
    [[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]];
    NSError* err = nil;
    NSHTTPURLResponse* rsp = nil;
    // Perform the request synchronously on this thread
    NSData *rspData = [NSURLConnection sendSynchronousRequest:request returningResponse:&rsp error:&err];
    if (rspData && err == nil) {
        NSDictionary *result = [NSJSONSerialization JSONObjectWithData:rspData options:NSJSONReadingMutableLeaves error:&err];
        if(result) {
            block(result, err);
        } else {
            block(nil, err);
        }
    }else{
        DLog(@"Requesting URL: %@  An error occured : %@",url,[err localizedDescription]);
        block(nil, err);
    }
}

我如何才能解决这个问题？

How i could solve this problem ?

推荐答案

您应该将以下委托方法添加到您的通信类中。

You should add below delegate methods to your communication class.

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
    if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust])
    {
        if ([YOUR_HOST isEqualToString:challenge.protectionSpace.host])
        {
            [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];
        }
    }
    [challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
}

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace
{
    return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust];
}
