项目中Android https请求地址遇到了这个异常(无终端认证):
javax.net.ssl.SSLPeerUnverifiedException: No peer certificate
是SSL协议中没有终端认证。
没有遇到过的问题,于是无奈的去找度娘。。。。。。。
看了不少大神的博客后得到的解决方案如下:
- /**
- * Post请求连接Https服务
- * @param serverURL 请求地址
- * @param jsonStr 请求报文
- * @return
- * @throws Exception
- */
- public static synchronized String doHttpsPost(String serverURL, String jsonStr)throws Exception {
- // 参数
- HttpParams httpParameters = new BasicHttpParams();
- // 设置连接超时
- HttpConnectionParams.setConnectionTimeout(httpParameters, 3000);
- // 设置socket超时
- HttpConnectionParams.setSoTimeout(httpParameters, 3000);
- // 获取HttpClient对象 (认证)
- HttpClient hc = initHttpClient(httpParameters);
- HttpPost post = new HttpPost(serverURL);
- // 发送数据类型
- post.addHeader("Content-Type", "application/json;charset=utf-8");
- // 接受数据类型
- post.addHeader("Accept", "application/json");
- // 请求报文
- StringEntity entity = new StringEntity(jsonStr, "UTF-8");
- post.setEntity(entity);
- post.setParams(httpParameters);
- HttpResponse response = null;
- try {
- response = hc.execute(post);
- } catch (UnknownHostException e) {
- throw new Exception("Unable to access " + e.getLocalizedMessage());
- } catch (SocketException e) {
- e.printStackTrace();
- }
- int sCode = response.getStatusLine().getStatusCode();
- if (sCode == HttpStatus.SC_OK) {
- return EntityUtils.toString(response.getEntity());
- } else
- throw new Exception("StatusCode is " + sCode);
- }
- private static HttpClient client = null;
- /**
- * 初始化HttpClient对象
- * @param params
- * @return
- */
- public static synchronized HttpClient initHttpClient(HttpParams params) {
- if(client == null){
- try {
- KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
- trustStore.load(null, null);
- SSLSocketFactory sf = new SSLSocketFactoryImp(trustStore);
- //允许所有主机的验证
- sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
- HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
- HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
- // 设置http和https支持
- SchemeRegistry registry = new SchemeRegistry();
- registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
- registry.register(new Scheme("https", sf, 443));
- ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);
- return new DefaultHttpClient(ccm, params);
- } catch (Exception e) {
- e.printStackTrace();
- return new DefaultHttpClient(params);
- }
- }
- return client;
- }
- public static class SSLSocketFactoryImp extends SSLSocketFactory {
- final SSLContext sslContext = SSLContext.getInstance("TLS");
- public SSLSocketFactoryImp(KeyStore truststore)
- throws NoSuchAlgorithmException, KeyManagementException,
- KeyStoreException, UnrecoverableKeyException {
- super(truststore);
- TrustManager tm = new X509TrustManager() {
- public java.security.cert.X509Certificate[] getAcceptedIssuers() {
- return null;
- }
- @Override
- public void checkClientTrusted(
- java.security.cert.X509Certificate[] chain,
- String authType)
- throws java.security.cert.CertificateException {
- }
- @Override
- public void checkServerTrusted(
- java.security.cert.X509Certificate[] chain,
- String authType)
- throws java.security.cert.CertificateException {
- }
- };
- sslContext.init(null, new TrustManager[] { tm }, null);
- }
- @Override
- public Socket createSocket(Socket socket, String host, int port,
- boolean autoClose) throws IOException, UnknownHostException {
- return sslContext.getSocketFactory().createSocket(socket, host,
- port, autoClose);
- }
- @Override
- public Socket createSocket() throws IOException {
- return sslContext.getSocketFactory().createSocket();
- }
- }
run下,小手发抖的点到测试按钮,深吸口气,咦?没反应。。。马蛋的,工作线程忘记start(),唉,再次run下,终于的有点反应了,神奇的竟然没有报之前的 javax.net.ssl.SSLPeerUnverifiedException: No peer certificate 的异常了。服务端的数据正常返回了。
分析问题:
HTTPS:超文本安全传输协议,和HTTP相比,多了一个SSL/TSL的认证过程,端口为443。
1.peer终端发送一个request,https服务端把支持的加密算法等以证书的形式返回一个身份信息(包含ca颁发机构和加密公钥等)。
2.获取证书之后,验证证书合法性。
3.随机产生一个密钥,并以证书当中的公钥加密。
4.request https服务端,把用公钥加密过的密钥传送给https服务端。
5.https服务端用自己的密钥解密,获取随机值。
6.之后双方传送数据都用此密钥加密后通信。
HTTPS流程清楚后,问题也就明显了,验证证书时,无法验证。
上面提供的解决方案就是添加默认信任全部证书。以此来通过接下来的通信。
但是,这样问题是解决了。但是觉得还是不带靠谱(信任全部证书有点危险)。继续噼噼啪啪的网上搜索一番。又找到了一种解决方案,其过程大致这样的:
1.浏览器访问https地址,保存提示的证书到本地,放到android项目中的assets目录。
2.导入证书,代码如下。
3.把证书添加为信任。
- public static String requestHTTPSPage(Context context, String mUrl) {
- InputStream ins = null;
- String result = "";
- try {
- ins = context.getAssets().open("my.key"); // 下载的证书放到项目中的assets目录中
- CertificateFactory cerFactory = CertificateFactory.getInstance("X.509");
- Certificate cer = cerFactory.generateCertificate(ins);
- KeyStore keyStore = KeyStore.getInstance("PKCS12", "BC");
- keyStore.load(null, null);
- keyStore.setCertificateEntry("trust", cer);
- SSLSocketFactory socketFactory = new SSLSocketFactory(keyStore);
- Scheme sch = new Scheme("https", socketFactory, 443);
- HttpClient mHttpClient = new DefaultHttpClient();
- mHttpClient.getConnectionManager().getSchemeRegistry().register(sch);
- BufferedReader reader = null;
- try {
- HttpGet request = new HttpGet();
- request.setURI(new URI(mUrl));
- HttpResponse response = mHttpClient.execute(request);
- if (response.getStatusLine().getStatusCode() != 200) {
- request.abort();
- return result;
- }
- reader = new BufferedReader(new InputStreamReader(response
- .getEntity().getContent()));
- StringBuffer buffer = new StringBuffer();
- String line = null;
- while ((line = reader.readLine()) != null) {
- buffer.append(line);
- }
- result = buffer.toString();
- } catch (Exception e) {
- e.printStackTrace();
- } finally {
- if (reader != null) {
- reader.close();
- }
- }
- } catch (Exception e) {
- e.printStackTrace();
- } finally {
- try {
- if (ins != null)
- ins.close();
- } catch (IOException e) {
- e.printStackTrace();
- }
- }
- return result;
