使用WeexSDK,网络请求信任证书的问题

使用0.18.0版本的weexSDK，并且是手动导入的SDK。

在项目中创建一个SDResourceRequest(名字随意)类继承WXResourceRequestHandlerDefaultImpl，遵循

WXResourceRequestHandler,NSURLSessionDelegate协议，如下图：

在SDResourceRequest.m中实现- (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential * _Nullable credential))completionHandler方法，代码如下：

- (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential * _Nullable credential))completionHandler {
 
    //AFNetworking中的处理方式
    NSURLSessionAuthChallengeDisposition disposition = NSURLSessionAuthChallengePerformDefaultHandling;
    __block NSURLCredential *credential = nil;
    //判断服务器返回的证书是否是服务器信任的
    if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]) {
        credential = [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust];
        /*disposition：如何处理证书
         NSURLSessionAuthChallengePerformDefaultHandling:默认方式处理
         NSURLSessionAuthChallengeUseCredential：使用指定的证书   
　　　　　 NSURLSessionAuthChallengeCancelAuthenticationChallenge：取消请求
         */
        if (credential) {
            disposition = NSURLSessionAuthChallengeUseCredential;
        } else {
            disposition = NSURLSessionAuthChallengePerformDefaultHandling;
        }
    } else {
        disposition = NSURLSessionAuthChallengeCancelAuthenticationChallenge;
    }
    //安装证书
    if (completionHandler) {
        completionHandler(disposition, credential);
    }
    
}

 

使用下面的方法无效，不知道为什么

- (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition, NSURLCredential * _Nullable))completionHandler{
    
    /*方法一 信任所有证书*/
    if([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]){
        NSURLCredential *credential = [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust];
        if(completionHandler)
            completionHandler(NSURLSessionAuthChallengeUseCredential,credential);
    }
}

 

使用cocoaPods导入WeexSDK应该没有问题，但是手动导入的WeexSDK可能没有WXResourceRequestHandlerDefaultImpl.h，可以在git上下载weexSDK源码把WXResourceRequestHandlerDefaultImpl.h放在外面，重新打包后在导入项目，如图：
