iOS笔记—NSURLConnection怎么把http改为https

来源：互联网发布：俄罗斯残奥会禁赛知乎编辑：程序博客网时间：2024/05/17 05:57

一直使用NSURLConnection请求HTTP接口，现在为了安全性的考虑打算使用HTTPS。

那么怎么修改呢？

1.不需要证书验证 ps:我们使用的就是这种

1.1 直接修改HTTP为HTTPS;

1.2 确认有 “Security.framework”

1.3 修改完成，可以直接请求了。

2.需要证书验证

其他的和1是一样的，只不过需要加下面方法.

- (void)connection:(NSURLConnection *)connection willSendRequestForAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge{     static CFArrayRef certs;        if (!certs) {            NSData*certData =[NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"srca" ofType:@"cer"]];            SecCertificateRef rootcert =SecCertificateCreateWithData(kCFAllocatorDefault,CFBridgingRetain(certData));            const void *array[1] = { rootcert };            certs = CFArrayCreate(NULL, array, 1, &kCFTypeArrayCallBacks);            CFRelease(rootcert);    // for completeness, really does not matter        }        SecTrustRef trust = [[challenge protectionSpace] serverTrust];        int err;        SecTrustResultType trustResult = 0;        err = SecTrustSetAnchorCertificates(trust, certs);        if (err == noErr) {            err = SecTrustEvaluate(trust,&trustResult);        }        CFRelease(trust);        BOOL trusted = (err == noErr) && ((trustResult == kSecTrustResultProceed)||(trustResult == kSecTrustResultConfirm) || (trustResult == kSecTrustResultUnspecified));        if (trusted) {            [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];        }else{            [challenge.sender cancelAuthenticationChallenge:challenge];        }}
