iOS 使用证书cer

使用证书.cer文件。在https请求中，保证数据的安全，防止中间人攻击和被网络监听

1. AFNetworking中的使用

   设置HTTPSessionManager对象的securityPolicy属性
   // 配置证书
   NSString *cerPath = [[NSBundle mainBundle] pathForResource:@"cf" ofType:@"cer"];
   NSData *cerData = [NSData dataWithContentsOfFile:cerPath];
   NSSet *cerSet = [[NSSet alloc] initWithObjects:cerData, nil];
   AFSecurityPolicy *securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModePublicKey];
   securityPolicy.allowInvalidCertificates = YES;
   securityPolicy.validatesDomainName = NO;
   securityPolicy.pinnedCertificates = cerSet;
   manager.securityPolicy = securityPolicy
   

   参考链接 iOS AFN https请求设置证书验证

2. SDWebImage中的使用

   重点是options: SDWebImageAllowInvalidSSLCertificates
   [imageView sd_setImageWithURL:[NSURL URLWithString:name] placeholderImage:[UIImage imageNamed:@"*.png"] options:SDWebImageAllowInvalidSSLCertificates];
   

3. 问题
   设置好后，遇到请求失败的问题

   彻底退出Charles即可
