iphone - iPhone 上的 "untrusted server certificate"

Question

我正在编写一个 iPhone 应用程序，我想连接到“HTTPS”服务器以获取一些信息。但是，我在控制台中收到错误

NSUnderlyingError = Error Domain=kCFErrorDomainCFNetwork Code=-1202 UserInfo=0x3e95cf0 "The certificate for this server is invalid. You might be connecting to a server that is pretending to be “example.com” which could put your confidential information at risk."; }

如何信任证书并获取http状态码200

以下是我的代码。

    NSMutableURLRequest *request_get2 = [[[NSMutableURLRequest alloc] init] autorelease];
    [request_get2 setURL:[NSURL URLWithString:@"https://www.example.com"]]; 
    [request_get2 setHTTPMethod:@"GET"];
    [request_get2 setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
    //[request_get2 setValue:@"text/html; charset=UTF-8" forHTTPHeaderField:@"Content-Type"];
    [request_get2 setValue:@"https://www.example.com" forHTTPHeaderField:@"Referer"];
    [request_get2 setHTTPShouldHandleCookies:YES];
    // cookiesString is in format "cookieName=cookieValue;"
    [request_get2 setValue: (NSString *) cookiesString forHTTPHeaderField:@"Cookie"];


    // doGet - response
    NSHTTPURLResponse *response_get2 = nil;  // it change from 'NSURLRespaonse' to 'NSHTTPURLResponse'
    NSError *error_get2 = nil;
    NSData *responseData_get2 = [NSURLConnection sendSynchronousRequest:request_get2 returningResponse:&response_get2 error:&error_get2];
    NSString *data_get2 = [[NSString alloc]initWithData:responseData_get2 encoding:NSUTF8StringEncoding];

    if (!error_get2) {
        NSString *responseURL_get2 = [[response_get2 URL] absoluteString];           // null value
        NSString *responseTextEncodingName_get2 = [response_get2 textEncodingName];  // null value
        NSString *responseMIMEType_get2 = [response_get2 MIMEType];                  // null value
        NSUInteger *responseStatusCode_get2 = [response_get2 statusCode]; //[responseStatusCode intValue]; // the status code is 0
    }
    else {
        NSLog(@"\nsomething went wrong: %@\n", [error_get2 userInfo]); // got the error in here
    }

我认为添加不受信任的证书(至少在模拟器中)是不可能的，但您可以告诉您的 NSURLConnection 委托(delegate)接受自签名证书(或通常不受信任的证书)
