iOS webview无法加载网页Domain=NSURLErrorDomain Code=-1202错误

我是靠谱客的博主虚拟戒指，最近开发中收集的这篇文章主要介绍iOS webview无法加载网页Domain=NSURLErrorDomain Code=-1202错误，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

错误

在应用中由 http转为 https 时, 报错了, 下面是错误:
NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9813)或者
Error Domain=NSURLErrorDomain Code=-1202 “The certificate for this server is invalid. “

原因

这是由于你的 https的证书失效, 或者是自建证书, 你需要跳过验证, 允许其进行服务器的连接.

请求错误中的解决方案

1.一般的,如果用的 AFN 的话你可以加上以下代码:

AFSecurityPolicy * securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeCertificate];
//allowInvalidCertificates 是否允许无效证书（也就是自建的证书），默认为NO
//如果是需要验证自建证书，需要设置为YES
securityPolicy.allowInvalidCertificates = YES;
//validatesDomainName 是否需要验证域名，默认为YES；
//假如证书的域名与你请求的域名不一致，需把该项设置为NO
//主要用于这种情况：客户端请求的是子域名，而证书上的是另外一个域名。因为SSL证书上的域名是独立的，假如证书上注册的域名是www.google.com，那么mail.google.com是无法验证通过的；当然，有钱可以注册通配符的域名*.google.com，但这个还是比较贵的。
securityPolicy.validatesDomainName = NO;
//validatesCertificateChain 是否验证整个证书链，默认为YES
//设置为YES，会将服务器返回的Trust Object上的证书链与本地导入的证书进行对比，这就意味着，假如你的证书链是这样的：
//GeoTrust Global CA 
//
Google Internet Authority G2
//
*.google.com
//那么，除了导入*.google.com之外，还需要导入证书链上所有的CA证书（GeoTrust Global CA, Google Internet Authority G2）；
//如是自建证书的时候，可以设置为YES，增强安全性；假如是信任的CA所签发的证书，则建议关闭该验证；
securityPolicy.validatesCertificateChain = NO;
requestOperationManager.securityPolicy = securityPolicy;

2.若还是不可进行请求, 你可以尝试在你的请求类中加入以下代码:

- (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential * __nullable credential))completionHandler{
NSLog(@"didReceiveChallenge");
//
if([challenge.protectionSpace.host isEqualToString:@"api.lz517.me"] /*check if this is host you trust: */ ){
completionHandler(NSURLSessionAuthChallengeUseCredential, [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust]);
//
}
}

3.加入代码后本人遇到的问题就解决了, 但是如果你的请求还有问题你可以参考以下,
