iOS 防止charles抓包

方案一:检查手机Wifi是否设置了代理

    public func fetchHttpProxy() -> Bool {
        guard let proxy = CFNetworkCopySystemProxySettings()?.takeUnretainedValue() else { return false }
        guard let dict = proxy as? [String: Any] else { return false }
        guard let HTTPProxy = dict["HTTPProxy"] as? String else { return false }
        if(HTTPProxy.count>0){
            return true;
        }
        return false;
    }

 1.以场景接口为例,设置了代理检测,手机开启代理,存在代理就直接返回,请求失败。

    func getSelectedFamilyDeviceSomeInfo(parameters : Any?, succeed : @escaping([String : Any]?) -> (), failure : @escaping(Error?) -> ()) {
        let requestUrl:String = SEVER_URL.appending("/developStage/devicegroup/v2/group/someInfo").addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)!
        print(parameters ?? "")
        NSLog("RequestUrl : "+requestUrl)
        
        if self.fetchHttpProxy() {
            print("++++++++++++设置了代理,不让请求=======")
            failure("设置了代理" as? Error)
            return
        }else{
            print("++++++++++++没设置代理,自由请求=======")
        }

        
        // 成功闭包
        let successBlock = { (task: URLSessionDataTask, responseObj: Any?) in
            succeed(responseObj as? [String : Any])
        }
        // 失败的闭包
        let failureBlock = { (task: URLSessionDataTask?, error: Error) in
            failure(error)
        }
        //accesstoken 加入请求头
        getAccessToken(success: {
            self.setHttpHeaderBasicProperty()
            self.post(requestUrl, parameters: parameters, progress: nil, success: successBlock, failure: failureBlock)
        }) {
            failure("Please sign in first" as? Error)
        }
    }

 

 

 2.注释代理检测,请求正常,界面正常展示,能抓取到场景接口数据

 

 

 方案二:对证书的验证

1.客户端需要证书(Certification file), .cer格式的文件。(找服务器要,有可能需要转化证书格式)

2、把证书加进项目中,把生成的.cer证书文件直接拖到你项目的相关文件夹中,记得勾选Copy items if neede和Add to targets。

3、参数名意思

AFSecurityPolicy

SSLPinningMode

AFSecurityPolicy是AFNetworking中网络通信安全策略模块。它提供三种SSL Pinning Mode

/**

 ## SSL Pinning Modes

 

 The following constants are provided by `AFSSLPinningMode` as possible SSL pinning modes.

 

 enum {

 AFSSLPinningModeNone,

 AFSSLPinningModePublicKey,

 AFSSLPinningModeCertificate,

 }

 

 `AFSSLPinningModeNone`

 Do not used pinned certificates to validate servers.

 

 `AFSSLPinningModePublicKey`

 Validate host certificates against public keys of pinned certificates.

 

 `AFSSLPinningModeCertificate`

 Validate host certificates against pinned certificates.

*/

AFSSLPinningModeNone:完全信任服务器证书;

AFSSLPinningModePublicKey:只比对服务器证书和本地证书的Public Key是否一致,如果一致则信任服务器证书;

AFSSLPinningModeCertificate:比对服务器证书和本地证书的所有内容,完全一致则信任服务器证书;

选择那种模式呢?

AFSSLPinningModeCertificate:最安全的比对模式。但是也比较麻烦,因为证书是打包在APP中,如果服务器证书改变或者到期,旧版本无法使用了,我们就需要用户更新APP来使用最新的证书。

AFSSLPinningModePublicKey:只比对证书的Public Key,只要Public Key没有改变,证书的其他变动都不会影响使用。
如果你不能保证你的用户总是使用你的APP的最新版本,所以我们使用AFSSLPinningModePublicKey。

allowInvalidCertificates

/**
 Whether or not to trust servers with an invalid or expired SSL certificates. Defaults to `NO`.
 */
@property (nonatomic, assign) BOOL allowInvalidCertificates;

是否信任非法证书,默认是NO。

validatesDomainName

/**
 Whether or not to validate the domain name in the certificate's CN field. Defaults to `YES`.
 */
@property (nonatomic, assign) BOOL validatesDomainName;

是否校验证书中DomainName字段,它可能是IP,域名如*.google.com,默认为YES,严格保证安全性。

4、使用AFSecurityPolicy设置SLL Pinning
