Android HTTPS请求总结

HttpClient

KeyStore keyStore;URI url = null;HttpGet req = null;

try{   //获取asset文件夹下的证书   AssetManager am = mContext.getAssets();   InputStream ins = am.open("my.crt"); //证书格式转换 IE 工具->internet->内容->证书

   try {      //读取证书      CertificateFactory cerFactory = CertificateFactory.getInstance("X.509");  //证书工厂。此处指明证书的类型      Certificate cer = cerFactory.generateCertificate(ins);      //创建一个证书库，并将证书导入证书库      keyStore = KeyStore.getInstance("PKCS12", "BC");   //问2  http://www.csdn.net/article/2015-01-06/2823434     keyStore.load(null, null);     keyStore.setCertificateEntry("trust", cer);   } finally {      ins.close();   }   //把咱的证书库作为信任证书库   SSLSocketFactory socketFactory = new SSLSocketFactory(keyStore);   Scheme sch = new Scheme("https", socketFactory, 443);   //完工   HttpClient mHttpClient = new DefaultHttpClient();   mHttpClient.getConnectionManager().getSchemeRegistry().register(sch);   url = new URI(gm.url+gm.param);   //url = new URI(gm.url+gm.param);   req = new HttpGet(url);   HttpGet requestGet = new HttpGet(url);   HttpResponse httpResponse = mHttpClient.execute(requestGet);   if (httpResponse.getStatusLine().getStatusCode() == 200) {      HttpEntity httpEntity = httpResponse.getEntity();      result = EntityUtils.toString(httpEntity);      result = result.replaceAll("\r", "");   }}catch (Exception e){}
