4）发起请求
NSString *url = @"xxxxxxxxxx";
// 1.获得请求管理者
AFHTTPRequestOperationManager *mgr = [AFHTTPRequestOperationManager manager];
//2设置https 请求
AFSecurityPolicy *securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeCertificate];
securityPolicy.allowInvalidCertificates = YES;
mgr.securityPolicy = securityPolicy;
// 3.发送POST请求
[mgr POST:url parameters:nil success:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) {
NSLog(@"responseObject: %@", responseObject);
} failure:^(AFHTTPRequestOperation * _Nonnull operation, NSError * _Nonnull error) {
NSLog(@"Error: %@", error);
}];
到此，老版的AFNetworking请求https接口的双向验证就做完了，但是有一个问题，这里需要改动AFNetworking的代码，何况新的AFNetworking已经有了，为了保持代码的活力，老的应该摒弃的，而且更新pods后肯定替换的代码就没了，也是一个问题，不要急，下面来说说怎么用新的AFNetworking，并解决被pods更新替换代码的问题。
最后再说一点，使用老的AF来请求，只用到了client.p12文件，并没有用到server.cer，在新的里面是有用到的，猜测可能是客户端选择信任任何证书导致的，就变成了单向的验证。
Demo放在最后
2.来说说新的AFNetworking3.x怎么来实现的
1）倒入client.p12和server.cer文件
2）plist内的设置，这是和上面一样的：
3）这里可不需要修改类里面的代码，但是这里需要重写一个方法：
NSString *url = @"https://www.easck.com/3.0.0/?service=City.GetCityList";
NSString *certFilePath = [[NSBundle mainBundle] pathForResource:@"server" ofType:@"cer"];
NSData *certData = [NSData dataWithContentsOfFile:certFilePath];
NSSet *certSet = [NSSet setWithObject:certData];
AFSecurityPolicy *policy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeCertificate withPinnedCertificates:certSet];
policy.allowInvalidCertificates = YES;
policy.validatesDomainName = NO;
_manager = [AFHTTPSessionManager manager];
_manager.securityPolicy = policy;
_manager.requestSerializer = [AFHTTPRequestSerializer serializer];
_manager.responseSerializer = [AFHTTPResponseSerializer serializer];
_manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/plain", nil];
//关闭缓存避免干扰测试r
_manager.requestSerializer.cachePolicy = NSURLRequestReloadIgnoringLocalCacheData;
[_manager setSessionDidBecomeInvalidBlock:^(NSURLSession * _Nonnull session, NSError * _Nonnull error) {
NSLog(@"setSessionDidBecomeInvalidBlock");
}];
//客户端请求验证 重写 setSessionDidReceiveAuthenticationChallengeBlock 方法
__weak typeof(self)weakSelf = self;
[_manager setSessionDidReceiveAuthenticationChallengeBlock:^NSURLSessionAuthChallengeDisposition(NSURLSession*session, NSURLAuthenticationChallenge *challenge, NSURLCredential *__autoreleasing*_credential) {
NSURLSessionAuthChallengeDisposition disposition = NSURLSessionAuthChallengePerformDefaultHandling;
__autoreleasing NSURLCredential *credential =nil;
if([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]) {
if([weakSelf.manager.securityPolicy evaluateServerTrust:challenge.protectionSpace.serverTrust forDomain:challenge.protectionSpace.host]) {
credential = [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust];
if(credential) {
disposition =NSURLSessionAuthChallengeUseCredential;
} else {
disposition =NSURLSessionAuthChallengePerformDefaultHandling;
}
} else {
disposition = NSURLSessionAuthChallengeCancelAuthenticationChallenge;
}
} else {
// client authentication
SecIdentityRef identity = NULL;
SecTrustRef trust = NULL;
NSString *p12 = [[NSBundle mainBundle] pathForResource:@"client"ofType:@"p12"];
NSFileManager *fileManager =[NSFileManager defaultManager];
if(![fileManager fileExistsAtPath:p12])
{
NSLog(@"client.p12:not exist");
}
else
{
NSData *PKCS12Data = [NSData dataWithContentsOfFile:p12];
if ([[weakSelf class]extractIdentity:&identity andTrust:&trust fromPKCS12Data:PKCS12Data])
{
SecCertificateRef certificate = NULL;
SecIdentityCopyCertificate(identity, &certificate);
const void*certs[] = {certificate};
CFArrayRef certArray =CFArrayCreate(kCFAllocatorDefault, certs,1,NULL);
credential =[NSURLCredential credentialWithIdentity:identity certificates:(__bridge NSArray*)certArray persistence:NSURLCredentialPersistencePermanent];
disposition =NSURLSessionAuthChallengeUseCredential;
}
}
}
*_credential = credential;
return disposition;
}];
