4）发起请求
//第三步和这一步代码是放在一起的，请注意哦
[_manager GET:url parameters:nil progress:^(NSProgress * _Nonnull downloadProgress) {
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers error:nil];
NSLog(@"JSON: %@", dic);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"Error: %@", error);
NSData *data = [error.userInfo objectForKey:@"com.alamofire.serialization.response.error.data"];
NSString *str = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"%@",str);
}];
另外还要加上一个方法：
+(BOOL)extractIdentity:(SecIdentityRef*)outIdentity andTrust:(SecTrustRef *)outTrust fromPKCS12Data:(NSData *)inPKCS12Data {
OSStatus securityError = errSecSuccess;
//client certificate password
NSDictionary*optionsDictionary = [NSDictionary dictionaryWithObject:@"证书密码"
forKey:(__bridge id)kSecImportExportPassphrase];
CFArrayRef items = CFArrayCreate(NULL, 0, 0, NULL);
securityError = SecPKCS12Import((__bridge CFDataRef)inPKCS12Data,(__bridge CFDictionaryRef)optionsDictionary,&items);
if(securityError == 0) {
CFDictionaryRef myIdentityAndTrust =CFArrayGetValueAtIndex(items,0);
const void*tempIdentity =NULL;
tempIdentity= CFDictionaryGetValue (myIdentityAndTrust,kSecImportItemIdentity);
*outIdentity = (SecIdentityRef)tempIdentity;
const void*tempTrust =NULL;
tempTrust = CFDictionaryGetValue(myIdentityAndTrust,kSecImportItemTrust);
*outTrust = (SecTrustRef)tempTrust;
} else {
NSLog(@"Failedwith error code %d",(int)securityError);
return NO;
}
return YES;
}
没错，我们是要封装一下，可是要怎么封装呢？博主尝试了集中都失败了，真是百思不得解，相信主动去封装的开发者也会碰到封装后请求失败的问题，也许你成功了，但是这里需要注意一个在block内使用变量的问题，具体的可以去看博主怎么封装的。
到这里，新的AF请求https就已经结束了，想看封装的，Demo放在最后。
3.单向验证
说到这个，不得不说一下网上的很多方法，都把单向验证当作双向的，其实也是并不理解其原理，关于原理，请看这里
代码实现AF都是一样的：
//AF加上这句和下面的方法
_manager.securityPolicy = [self customSecurityPolicy];
/**** SSL Pinning ****/
- (AFSecurityPolicy*)customSecurityPolicy {
NSString *cerPath = [[NSBundle mainBundle] pathForResource:@"server" ofType:@"cer"];
NSData *certData = [NSData dataWithContentsOfFile:cerPath];
AFSecurityPolicy *securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeCertificate];
[securityPolicy setAllowInvalidCertificates:YES];
NSSet *set = [NSSet setWithObjects:certData, nil];
[securityPolicy setPinnedCertificates:@[certData]];
/**** SSL Pinning ****/
return securityPolicy;
}
