iOS HTTPS 自检证书请求服务器和WKWebView

1、使用AFN3.0 HTTPS网络请求

    +(AFSecurityPolicy *)customSecurityPolicy{     //简单封装一下

    //2 设置证书模式
    NSString *cerPath = [[NSBundle mainBundle] pathForResource:@"mnchip" ofType:@"cer"];

    NSData *cerDat = [NSData dataWithContentsOfFile:cerPath];

    AFSecurityPolicy *securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeCertificate];

    //允许自检证书
    securityPolicy.allowInvalidCertificates = YES;

    //域名与服务器一致
    securityPolicy.validatesDomainName = YES;

    securityPolicy.pinnedCertificates = [[NSSet alloc] initWithObjects:cerDat, nil];

    return securityPolicy;

    }

在有网络请求的地方：

******

    AFHTTPSessionManager *session = [AFHTTPSessionManager manager];
    //添加证书
    [session setSecurityPolicy:[OperationHelper customSecurityPolicy]];

******

这样就可以了

2、关于WKWebView ， 我是将Allow Arbitrary Loads in Web Content 置为 yes，然后正常使用，注意一点，要实现这个代理方法

    - (void)webView:(WKWebView *)webView didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential * _Nullable credential))completionHandler{

    if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]) {

    NSURLCredential *card = [[NSURLCredential alloc]initWithTrust:challenge.protectionSpace.serverTrust];

    completionHandler(NSURLSessionAuthChallengeUseCredential,card);

    }}

@implementation NSURLRequest(DataController)
+ (BOOL)allowsAnyHTTPSCertificateForHost:(NSString *)host
{
    return YES;
}
@end

关于WKWebView就可以正常显示了

3、UIWebView 访问https 绕过证书验证的方法

在AppDelegate.m里面添加下面这些代码

@implementation NSURLRequest(DataController)
+ (BOOL)allowsAnyHTTPSCertificateForHost:(NSString *)host
{
    return YES;
}
@end
