應(yīng)該有很多小伙伴遇到這樣一個(gè)問題，在線上已發(fā)布的app里，關(guān)于https的cer證書過期，從而導(dǎo)致app所有網(wǎng)絡(luò)請(qǐng)求失效無法使用，這篇文章主要介紹了Android Https證書過期的解決方案,需要的朋友可以參考下

這個(gè)時(shí)候有人就要說了，應(yīng)急發(fā)布一個(gè)已更新最新cer證書的apk不就完事了么，其實(shí)沒那么簡單，iOS還好可以通過appstore提供的api查詢到新版本，但android就不一樣了，需要調(diào)用自己Server端提供的api接口查詢到新版本，并獲取apk下載路徑，問題是https都不能訪問了，如何請(qǐng)求到版本信息呢？下面提供兩種常見的解決方案：

方案一

將版本信息接口讓后臺(tái)改成http（不推薦，后臺(tái)因素不可控），或者將本地https的設(shè)置一個(gè)不安全校驗(yàn)（推薦）。

private static OkHttpClient newOkHttpClient(int timeout){
 
        HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
        logging.setLevel(HttpLoggingInterceptor.Level.BODY);
 
        return new OkHttpClient.Builder()
                .addInterceptor(new RequestInfoInterceptor())
                //.addInterceptor(logging)
                .addNetworkInterceptor(new TokenHeaderInterceptor())
                .sslSocketFactory(Certificate.getSSLSocketFactory())
                //設(shè)置不安全校驗(yàn)
                .hostnameVerifier(Certificate.getUnSafeHostnameVerifier())
                .readTimeout(timeout, TimeUnit.SECONDS)
                .writeTimeout(timeout, TimeUnit.SECONDS)
                .build();
    }
 
    /**
     *獲取HostnameVerifier 
     */
    public static HostnameVerifier getUnSafeHostnameVerifier() {
        HostnameVerifier hostnameVerifier = new HostnameVerifier() {
            @Override
            public boolean verify(String s, SSLSession sslSession) {
                return true;
            }
        };
        return hostnameVerifier;
    }

方案二

將xxx.cer證書改成動(dòng)態(tài)讀?。ㄒ晕募姆绞綇腶pp沙盒里面讀取即可），在https證書即將過期時(shí)，從服務(wù)器下載最新的cer證書更新到沙盒里面，App每次初始化網(wǎng)絡(luò)請(qǐng)求時(shí)讀取sdcard最新的證書文件，這樣App就永遠(yuǎn)不會(huì)出現(xiàn)https證書過期導(dǎo)致無法使用的問題，流程圖如下。

在這里插入圖片描述

下面是一些關(guān)鍵的代碼：

    private static OkHttpClient newOkHttpClient(int timeout){
 
        HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
        logging.setLevel(HttpLoggingInterceptor.Level.BODY);
 
        return new OkHttpClient.Builder()
                .addInterceptor(new RequestInfoInterceptor())
                //.addInterceptor(logging)
                .addNetworkInterceptor(new TokenHeaderInterceptor())
                .sslSocketFactory(Certificate.getSSLSocketFactory(BaseApplcation.myApp, new String[]{"/sdcard/xxx.cer"}))
                .hostnameVerifier(Certificate.getUnSafeHostnameVerifier())
                .readTimeout(timeout, TimeUnit.SECONDS)
                .writeTimeout(timeout, TimeUnit.SECONDS)
                .build();
    }
  
    /**

            keyStore.load(null, null);
 
            for (int i = 0; i < certificatesFiles.length; i++) {
                InputStream certificate = new FileInputStream(certificatesFiles[i]);
                keyStore.setCertificateEntry(String.valueOf(i), certificateFactory.generateCertificate(certificate));
 
                if (certificate != null) {
                    certificate.close();
                }

        return null;
    }
 
  /**

    public static SSLSocketFactory getSSLSocketFactory(Context context, int[] certificates) {

            for (int i = 0; i < certificates.length; i++) {
                InputStream certificate = context.getResources().openRawResource(certificates[i]);
                keyStore.setCertificateEntry(String.valueOf(i), certificateFactory.generateCertificate(certificate));
 
                if (certificate != null) {
                    certificate.close();
                }
