iOS开发实现HTTPS之cer文件的使用详解

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

 //证书
 AFSecurityPolicy *securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeCertificate];
 manager.securityPolicy = securityPolicy;
 // 2.设置证书模式
 NSString * cerPath = [[NSBundle mainBundle] pathForResource:@"tomcat" ofType:@"cer"]; //tomcat是cer文件的名称
 NSData * cerData = [NSData dataWithContentsOfFile:cerPath];
 manager.securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeCertificate withPinnedCertificates:[[NSSet alloc] initWithObjects:cerData, nil]];
 // 客户端是否信任非法证书
 manager.securityPolicy.allowInvalidCertificates = YES;
 // 是否在证书域字段中验证域名
 [manager.securityPolicy setValidatesDomainName:NO];
