本文介绍了如何在Android和iOS平台上解决Weex不支持HTTPS的问题。在Android上，通过扩展并注册自定义的HTTP适配器来处理HTTPS请求。在iOS上，继承`WXResourceRequestHandlerDefaultImpl`并实现`NSURLSessionDataDelegate`，在`URLSession:didReceiveChallenge:completionHandler:`方法中处理证书信任，从而支持HTTPS连接。

在android上：
扩展一个Adapter，继承DefaultWXHttpAdapter

public class BingoWXHttpAdapter extends DefaultWXHttpAdapter {

    @Override
    protected HttpURLConnection createConnection(URL url) throws IOException {
        HttpURLConnection conn = null;
        if (url.getProtocol().toLowerCase().equals("https")) {
            trustAllHosts();
            HttpsURLConnection httpsCon = (HttpsURLConnection) url.openConnection();
            httpsCon.setHostnameVerifier(DO_NOT_VERIFY);
            conn = httpsCon;
        } else {
            conn = (HttpURLConnection) url.openConnection();
        }
        return conn;
    }

    //host不验证
    private HostnameVerifier DO_NOT_VERIFY = new HostnameVerifier() {
        public boolean verify(String hostname, SSLSession session) {
            return true;
        }
    };

    //信任所有证书
    private static void trustAllHosts() {
        final String TAG = "trustAllHosts";
        TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager() {
            public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                return new java.security.cert.X509Certificate[]{};
            }

            public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
                Log.i(TAG, "checkClientTrusted");
            }

            public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
                Log.i(TAG, "checkServerTrusted");
            }
        }};

        try {
            SSLContext sc = SSLContext.getInstance("TLS");
            sc.init(null, trustAllCerts, new java.security.SecureRandom());
            HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

之后在初始化Engine的时候注册它：

setHttpAdapter(new BingoWXHttpAdapter())

在iOS上
继承WXResourceRequestHandlerDefaultImpl实现didReceiveChallenge，具体代码如下：

#import <Foundation/Foundation.h>
#import "WXResourceRequestHandlerDefaultImpl.h"
#import "WXResourceRequestHandler.h"

@interface BingoWXNetworkImpl : WXResourceRequestHandlerDefaultImpl <WXResourceRequestHandler,NSURLSessionDataDelegate>

@end

#import "BingoWXNetworkImpl.h"

@implementation BingoWXNetworkImpl

- (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge
completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential * __nullable credential))completionHandler {

// NSURLSessionAuthChallengeUseCredential = 0, 使用（信任）证书
// NSURLSessionAuthChallengePerformDefaultHandling = 1, 默认，忽略
// NSURLSessionAuthChallengeCancelAuthenticationChallenge = 2, 取消
// NSURLSessionAuthChallengeRejectProtectionSpace = 3, 这次取消，下载次还来问

NSLog(@"%@>>>>>>>>>>>>>>>>>>>>>>>>",challenge.protectionSpace);
// 如果是请求证书信任，我们再来处理，其他的不需要处理
if (challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust) {
NSURLCredential *cre = [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust];
// 调用block
completionHandler(NSURLSessionAuthChallengeUseCredential,cre);
}
}
@end
