App中HTTPS设置

为了安全方面的考虑,项目想改用HTTPS进行数据传输.目前项目所用的网络请求是AFN2.6版本的,默认不支持HTTPS网址进行数据请求,错误代码:

[code]2016-01-20 08:49:00.780 TestHttps[1494:30088] CFNetwork SSLHandshake failed (-9824)
2016-01-20 08:49:00.781 TestHttps[1494:30088] NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9824)

根据网上资料进行修改:

在Info.plist添加字段App Transport Security Settings,设置为YES

一:第一种方法是在网络请求类中添加

[code]AFSecurityPolicy * policy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeNone];
policy.allowInvalidCertificates = YES;
policy.validatesDomainName = NO;
manager.securityPolicy = policy;

二:第二种方法是

(1)下载网站的证书导入工程

(2)新建类方法

[code]//自定义安全策略
+ (AFSecurityPolicy*)customSecurityPolicy
{
    // /先导入证书
    NSString *cerPath = [[NSBundle mainBundle] pathForResource:@"example" ofType:@"cer"];//证书的路径
//    NSString * cerPath = [[NSBundle mainBundle]pathForResource:@"https" ofType:@"cer"];

//    NSLog(@"%@",cerPath);
    NSData *certData = [NSData dataWithContentsOfFile:cerPath];
//    NSLog(@"%@",certData);
//    NSSet * certSet = [[NSSet alloc] initWithObjects:certData, nil];

    // AFSSLPinningModeCertificate 使用证书验证模式
    AFSecurityPolicy *securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeCertificate];

    // allowInvalidCertificates 是否允许无效证书（也就是自建的证书），默认为NO
    // 如果是需要验证自建证书，需要设置为YES
    securityPolicy.allowInvalidCertificates = YES;

    //validatesDomainName 是否需要验证域名，默认为YES；
    //假如证书的域名与你请求的域名不一致，需把该项设置为NO；如设成NO的话，即服务器使用其他可信任机构颁发的证书，也可以建立连接，这个非常危险，建议打开。
    //置为NO，主要用于这种情况：客户端请求的是子域名，而证书上的是另外一个域名。因为SSL证书上的域名是独立的，假如证书上注册的域名是www.google.com，那么mail.google.com是无法验证通过的；当然，有钱可以注册通配符的域名*.google.com，但这个还是比较贵的。
    //如置为NO，建议自己添加对应域名的校验逻辑。
    securityPolicy.validatesDomainName = NO;

    securityPolicy.pinnedCertificates = @[certData];

    return securityPolicy;
}

(3)修改AFN源码,如图




这样就可以用https网址进行数据请求了.

后记:HTTPS协议还有SSL还很不清楚,计算机基础差,以后急需补充.
