最近在调用一些https的接口，然后采用的认证方式是用户名+密码。
这个时候调用接口则会提示httpclient未认证的错误，导致接口无法调用：
HttpClient javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated。
出现此问题主要是在请求过程中证书的问题，程序使用的客户端并未安装服务器要求的证书，所以会产生此问题。
下面是我找到的解决方法。
方法一： httpClient jar包版本为4.1.x
public static HttpClient getHttpClient(HttpClient base) {
try {
SSLContext ctx = SSLContext.getInstance("SSL");
X509TrustManager tm = new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
@Override
public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {}
@Override
public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {}
};
ctx.init(null, new TrustManager[] { tm }, null);
SSLSocketFactory ssf = new SSLSocketFactory(ctx, SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
ClientConnectionManager mgr = base.getConnectionManager();
SchemeRegistry registry = mgr.getSchemeRegistry();
registry.register(new Scheme("https", 443, ssf));
return new DefaultHttpClient(mgr, base.getParams());
} catch (Exception e) {
logger.warn("{}", e);
return null;
}
}调用的方法如下：
HttpClient httpClient = ToolUtil.getHttpClient(new DefaultHttpClient());此时问题已经完美解决了。
然而在之后的使用过程中，我发现4.1版本的httpClient jar包里面没有httpPatch，但最新的4.5版本是有的。于是果断用最新的4.5.3版本的httpClient包。
用了这个jar包之后满屏幕的删除线，很多代码都被@Deprecated注解掉了。改！
解决HttpClient javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated这个问题的代码当然也是要随着一起改的了，于是乎我找到了方法二。
方法二： httpClient jar包为4.5.x版本。
public static CloseableHttpClient getHttpClient() {
try {
SSLContext sslContext = SSLContext.getInstance("SSL");
sslContext.init(null, new TrustManager[]{new X509TrustManager() {
@Override
public void checkClientTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
}
@Override
public void checkServerTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
}
@Override
public X509Certificate[] getAcceptedIssuers() {
return new X509Certificate[0];
}
}}, new SecureRandom());
SSLConnectionSocketFactory socketFactory = new SSLConnectionSocketFactory(sslContext, NoopHostnameVerifier.INSTANCE);
CloseableHttpClient closeableHttpClient = HttpClientBuilder.create().setSSLSocketFactory(socketFactory).build();
return closeableHttpClient;
} catch (Exception e) {
logger.warn("create closeable http client failed!");
return HttpClientBuilder.create().build();
}
}httpClient = ToolUtil.getHttpClient();在这个里面我遇到的最大问题是SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER 竟然也被@Deprecated注释了。然后终于找到了一个替代方案：用NoopHostnameVerifier.INSTANCE替换之。这个是在 http://stackoverflow.com/questions/23201648/httpclient-4-3-x-fixing-deprecated-code-to-use-current-httpclient-implementatio 最下面一个答案中找到的。
最后附上完整的java代码，主要是给出import头文件。
