项目中使用的框架是AFNetworking 3.0及以上版本,由于ATS的原因,iOS只允许使用Https开头的链接,在2016年12月30日以前苹果允许绕开ATS,如下图所示:

但是从2017年1月1日开始将不再接受使用http加载资源的应用,因此本篇文章主要讲解如何使用AFN进行自签名证书的通过认证(注:对于使用CA机构认证的证书不需要进行认证,直接使用Https开头的链接进行数据访问和加载页面即可)项目已经上传至GitHub(需要参考源码的话请点击链接):

https://github.com/AustinKuture/HttpsSignatureCertificate

1,建立一个根类 此处命名为AKNetPackegeAFN

 1>  .h文件 ,创建所需要的Get 与 Post 方法

#import <Foundation/Foundation.h>


typedef enum{
    
    AKNetWorkGET ,   /**< GET请求 */
    AKNetWorkPOST = 1 /**< POST请求 */
}AKNetWorkType;
typedef void (^HttpSuccess)(id json);
typedef void (^HttpErro)(NSError* error);
@interface AKNetPackegeAFN : NSObject

+(instancetype)shareHttpManager;

/*
 *
 netWorkType:请求方式 GET 或 POST
 signature:是否使用签名证书,是的话直接写入证书名字,否的话填nil
 api:请求的URL接口
 parameters:请求参数
 sucess:请求成功时的返回值
 fail:请求失败时的返回值
 *
 */

- (void)netWorkType:(AKNetWorkType)netWorkType Signature:(NSString *)signature API:(NSString *)api Parameters:(NSDictionary *)parameters Success:(HttpSuccess)sucess Fail:(HttpErro)fail;

@end

2> .m文件,导入头文件AFNetworking.h 新建Manager 属性并实现shareHttpManager类方法

#import "AKNetPackegeAFN.h"
#import "AFNetworking.h"

@interface AKNetPackegeAFN()

@property (nonatomic,strong) AFHTTPSessionManager *manager;

@end

@implementation AKNetPackegeAFN


+(instancetype)shareHttpManager{
    static dispatch_once_t onece = 0;
    static AKNetPackegeAFN *httpManager = nil;
    dispatch_once(&onece, ^(void){
        httpManager = [[self alloc]init];
    });
    return httpManager;
}

2,Get 与Post 方法的实现

   使用时将后台所给的证书转换为 .cer格式 拖入项目根目录中,在方法中进行绑定即可例如后台给的证书名为:Kuture.crt  收到证书后双击进行安装,然后打开钥匙串,将名为Kuture的证书右击导出,选择后缀为.cer 然后确定即可 如下图所示:

GET 与 POST 实现方法的封装

- (void)netWorkType:(AKNetWorkType)netWorkType Signature:(NSString *)signature API:(NSString *)api Parameters:(NSDictionary *)parameters Success:(HttpSuccess)sucess Fail:(HttpErro)fail{
    
    //开启证书验证模式
    AFSecurityPolicy *securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeCertificate];
    
    //是否允许使用自签名证书
    signature == nil ? (void)(securityPolicy.allowInvalidCertificates = NO):(securityPolicy.allowInvalidCertificates = YES);
    
    //是否需要验证域名
    securityPolicy.validatesDomainName = NO;
    
    _manager = [[AFHTTPSessionManager alloc]initWithBaseURL:[NSURL URLWithString:api]];
    _manager.responseSerializer = [AFJSONResponseSerializer serializer];
    _manager.securityPolicy = securityPolicy;
    _manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json",@"application/xml",@"text/xml",@"text/json",@"text/plain",@"text/javascript",@"text/html", nil];
    
    if (signature != nil){
        
        __weak typeof(self) weakSelf = self;
        [_manager setSessionDidReceiveAuthenticationChallengeBlock:^NSURLSessionAuthChallengeDisposition(NSURLSession *session, NSURLAuthenticationChallenge *challenge, NSURLCredential *__autoreleasing *_credential) {
            
            //获取服务器的 trust object
            SecTrustRef serverTrust = [[challenge protectionSpace] serverTrust];
            
            //导入自签名证书
            NSString *cerPath = [[NSBundle mainBundle] pathForResource:@"你的证书名字" ofType:@"cer"];
            NSData *cerData = [NSData dataWithContentsOfFile:cerPath];
            
            if (!cerData) {
                
                NSLog(@"==== .cer file is nil ====");
                
                return 0;
            }
            
            NSArray *cerArray = @[cerData];
            weakSelf.manager.securityPolicy.pinnedCertificates = cerArray;
            SecCertificateRef caRef = SecCertificateCreateWithData(NULL, (__bridge CFDataRef)cerData);
            NSCAssert(caRef != nil, @"caRef is nil");
            
            NSArray *caArray = @[(__bridge id)(caRef)];
            NSCAssert(caArray != nil, @"caArray is nil");
            
            //将读取到的证书设置为serverTrust的根证书
            OSStatus status = SecTrustSetAnchorCertificates(serverTrust, (__bridge CFArrayRef)caArray);
            SecTrustSetAnchorCertificatesOnly(serverTrust, NO);
            NSCAssert(errSecSuccess == status, @"SectrustSetAnchorCertificates failed");
            
            //选择质询认证的处理方式
            NSURLSessionAuthChallengeDisposition disposition = NSURLSessionAuthChallengePerformDefaultHandling;
            __autoreleasing NSURLCredential *credential = nil;
            
            //NSURLAuthenTicationMethodServerTrust质询认证方式
            if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]) {
                //基于客户端的安全策略来决定是否信任该服务器,不信任则不响应质询
                if ([weakSelf.manager.securityPolicy evaluateServerTrust:challenge.protectionSpace.serverTrust forDomain:challenge.protectionSpace.host]) {
                    
                    //创建质询证书
                    credential = [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust];
                    
                    //确认质询方式
                    if (credential) {
                        disposition = NSURLSessionAuthChallengeUseCredential;
                        
                    } else {
                        
                        disposition = NSURLSessionAuthChallengePerformDefaultHandling;
                    }
                    
                } else {
                    
                    //取消挑战
                    disposition = NSURLSessionAuthChallengeCancelAuthenticationChallenge;
                }
                
            } else {

        }];
    }
    
    if (netWorkType == 0){
        
        [_manager GET:api parameters:parameters progress:^(NSProgress * _Nonnull uploadProgress) {
        } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
            
            if (sucess){
                
                sucess(responseObject);
            }else{
                
                NSLog(@"链接异常或网络不存在");
            }
        } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
            
            fail(error);
        }];

    }else if (netWorkType == 1){

            fail(error);
        }];

    }
    
    
}

 

2  使用方法,在需要进行数据获取或传递的类里面,直接导入头文件 AKNetPackegeAFN.h ,并实现方法即可,如下所示:

//创建对象
    //如果是自签名证书,使用前先到AKNetPackegeAFN相应的方法里进行证书的绑定(证书直接拖入项目中)即可
    /*
     *
     netWorkType:请求方式 GET 或 POST
     signature:是否使用签名证书,是的话直接写入证书名字,否的话填nil
     api:请求的URL接口
     parameters:请求参数
     sucess:请求成功时的返回值
     fail:请求失败时的返回值
     *
     */
    
    AKNetPackegeAFN *netHttps = [AKNetPackegeAFN shareHttpManager];
    [netHttps netWorkType:请求类型 Signature:证书名称 API:请求URL Parameters:参数 Success:^(id json) {
        
        NSLog(@"Json:%@",json);
    } Fail:^(NSError *error) {
        
        NSLog(@"Error:%@",error);
    }];
