ios项目绕过证书访问https程序_移动开发_编程开发_程序员俱乐部

如果是单个的webview或者request请求，在请求的文件h中直接实现NSURLConnectionDelegate，并在m中添加下列实现下列两个方法：

1. - (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace {  
2.     return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust];  
3. }  
4.   
5. - (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {  
6.     if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust])  
7.         //if ([trustedHosts containsObject:challenge.protectionSpace.host])  
8.             [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust]   
9.                  forAuthenticationChallenge:challenge];    
10.     [challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];  
11. }  

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

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

 上述方法很不爽的是每个请求的地方都要加。

 

如果项目中用到了three20，直接修改“TTRequestLoader.m”即可，这个文件本身就已经实现了NSURLConnectionDelegate，

 

修改如下，只改这一个地方就行，处处可用。
