Ⅰ 怎么给httpclient 配置https证书
你那个 SSLSocketFactory(ks) 是自己的类?
你有用过 KeyManager.init (...)? 和 TrustManager.init(...) ?
想要在连接建立过程上交互式的弹出确认对话框专来的话需要我们自属己提供一个 KeyManager 和 TrustManager 的实现类,这有点复杂,你可以看一个 Sun 的 X509KeyManager 是怎么做的,默认地情况下它是从自动搜索匹配的 subject ,我们需要用自己提供的方式弹出确认的过程还不是全自动,另外一个账户可能有多个数字证书,比如支付宝我们就有多个签发时间不一样的数字证书,在连接建立时 IE 会提示我们选择其中的一个来使用,银行的 U 盾在安装多张数字证书时也会提示我们选择其中一个对应到你正在使用的银行卡号的那张证书。
Ⅱ 如何httpclient访问https
很多情况下,需要通过程序抓取网页或者调用接口获取数据。使用apache的httpClient是一个最常用的开源的java第三方工具包。那么如何访问https的地址呢?
工具/原料
jdk
httpclent.jar
IDE(eg.Eclipse)或者文本编辑器 有一个就可以
方法/步骤
下载httpclient
网络一下:apache httpclient,还是看截图吧

Ⅲ httpclient 支持https吗
直接上代码,做一个创建client的工具类
public static CloseableHttpClient createSSLClientDefault(){
try {
SSLContext sslContext = new SSLContextBuilder().loadTrustMaterial(null, new TrustStrategy() {
//信任所有
public boolean isTrusted(X509Certificate[] chain,
String authType) throws CertificateException {
return true;
}
}).build();
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext);
return HttpClients.custom().setSSLSocketFactory(sslsf).build();
} catch (KeyManagementException e) {
e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (KeyStoreException e) {
e.printStackTrace();
}
return HttpClients.createDefault();
}
下面就可以通过这个client访问https的url地址
关键代码:
//上面的工具类
CloseableHttpClient httpClient = HttpClientUtil.createSSLClientDefault();
HttpGet get = new HttpGet();
get.setURI(new URI("你的https://地址"));
httpClient.execute(get)
//...........后续操作
Ⅳ HttpClient 怎么忽略证书验证访问https
您好,我来为您解答:
自定义一个SSLSocketFactory,忽略证书的验证。
如果我的回答没能帮助您,请继续追问。
Ⅳ httpclient支持https吗
支持,
默认情况下,如果你访问的https站点颁发者证书存在于jre的cacerts中,直接用就可以;
如果你访问的https站点不是内置颁发者:如12xx6那个XX网站的https。。。那就得费点功夫
简单理解: 请用浏览器访问那个https url,如果没警告,一般情况下直接用就可的
Ⅵ 如何使用httpclient访问双向ssl认证的网站
首先
create a custom class from org.apache.http.conn.ssl.SSLSocketFactory
Java code?
public class MySSLSocketFactory extends SSLSocketFactory {
SSLContext sslContext = SSLContext.getInstance("TLS");
public MySSLSocketFactory(KeyStore truststore) throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException {
super(truststore);
TrustManager tm = new X509TrustManager() {
public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
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();
}
}
然后
Java code?
//SSLSocketFactory socketFactory = new SSLSocketFactory(trustStore);
SSLSocketFactory socketFactory = new MySSLSocketFactory(trustStore);
socketFactory.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
Scheme sch = new Scheme("https", socketFactory, 8443);
httpclient.getConnectionManager().getSchemeRegistry().register(sch);
...
Ⅶ Java的HttpClient如何去支持无证书访问https
项目里需要访问其他接口,通过http/https协议。我们一般是用HttpClient类来实现具体的http/https协议接口的调用。
// Init a HttpClient
HttpClient client = new HttpClient();
String url=http://www.xxx.com/xxx;
// Init a HttpMethod
HttpMethod get = new GetMethod(url);
get.setDoAuthentication(true);
get.getParams().setParameter(HttpMethodParams.RETRY_HANDLER, new DefaultHttpMethodRetryHandler(1, false));
// Call http interface
try {
client.executeMethod(get);
// Handle the response from http interface
InputStream in = get.getResponseBodyAsStream();
SAXReader reader = new SAXReader();
Document doc = reader.read(in);
} finally {
// Release the http connection
get.releaseConnection();
}
以上代码在通过普通的http协议是没有问题的,但如果是https协议的话,就会有证书文件的要求了。一般情况下,是这样去做的。
// Init a HttpClient
HttpClient client = new HttpClient();
String url=https://www.xxx.com/xxx;
if (url.startsWith("https:")) {
System.setProperty("javax.net.ssl.trustStore", "/.sis.cer");
System.setProperty("javax.net.ssl.trustStorePassword", "public");
}
于是,这里就需要事先生成一个.sis.cer的文件,生成这个文件的方法一般是先通过浏览器访问https://,导出证书文件,再用JAVA keytool command 生成证书
# $JAVA_HOME/bin/keytool -import -file sis.cer -keystore .sis.cer
但这样做,一比较麻烦,二来证书也有有效期,过了有效期之后,又需要重新生成一次证书。如果能够避开生成证书文件的方式来使用https的话,就比较好了。
还好,在最近的项目里,我们终于找到了方法。
// Init a HttpClient
HttpClient client = new HttpClient();
String url=https://www.xxx.com/xxx;
if (url.startsWith("https:")) {
this.supportSSL(url, client);
}
用到了supportSSL(url, client)这个方法,看看这个方法是如何实现的。
private void supportSSL(String url, HttpClient client) {
if(StringUtils.isBlank(url)) {
return;
}
String siteUrl = StringUtils.lowerCase(url);
if (!(siteUrl.startsWith("https"))) {
return;
}
try {
setSSLProtocol(siteUrl, client);
} catch (Exception e) {
logger.error("setProtocol error ", e);
}
Security.setProperty( "ssl.SocketFactory.provider",
"com.tool.util.DummySSLSocketFactory");
}
private static void setSSLProtocol(String strUrl, HttpClient client) throws Exception {
URL url = new URL(strUrl);
String host = url.getHost();
int port = url.getPort();
if (port <= 0) {
port = 443;
}
ProtocolSocketFactory factory = new SSLSocketFactory();
Protocol authhttps = new Protocol("https", factory, port);
Protocol.registerProtocol("https", authhttps);
// set https protocol
client.getHostConfiguration().setHost(host, port, authhttps);
}
在supportSSL方法里,调用了Security.setProperty( "ssl.SocketFactory.provider",
"com.tool.util.DummySSLSocketFactory");
那么这个com.tool.util.DummySSLSocketFactory是这样的:
访问https 资源时,让httpclient接受所有ssl证书,在weblogic等容器中很有用

54. );
55. }

85. socket.bind(localaddr);
86. socket.connect(remoteaddr, timeout);
87. return socket;
88. }
89. }

91. //自定义私有类

}
private SSLContext sslcontext = null;
private SSLContext createSSLContext() {

try {
sslcontext = SSLContext.getInstance("SSL");
sslcontext.init(null, new TrustManager[]{new TrustAnyTrustManager()}, new java.security.SecureRandom());

socket,
host,
port,
autoClose
);
}
public Socket createSocket(String host, int port) throws IOException,
UnknownHostException {
return getSSLContext().getSocketFactory().createSocket(
host,
port
然后按如下方式使用HttpClient
Protocol myhttps = new Protocol("https", new MySecureProtocolSocketFactory (), 443);
Protocol.registerProtocol("https", myhttps);
HttpClient httpclient=new HttpClient();
Ⅷ 请教httpclient访问https,我的步骤错哪里了
首先是服务端如何支持https的问题,步骤如下。
1、生成服务端证书,cmd命令:
keytool -genkey -alias tomcat -keyalg RSA
或者
keytool -genkey -alias jboss -keyalg RSA
按照提示输入一些信息,如果是本机调试,用户名最好输入localhost,否则会出现不匹配异常。
完成后,系统默认把文件放在我的文档里面,名字默认是.keystore。
把文件复制到jboss-5.1.0.GA\server\default\conf下面。
2、在jboss-5.1.0.GA\server\default\deploy\jbossweb.sar\打开server.xml,找到如下:
<!-- SSL/TLS Connector configuration using the admin devl guide keystore-->
<Connector protocol="HTTP/1.1" SSLEnabled="true"
port="443" address="${jboss.bind.address}"
scheme="https" secure="true" clientAuth="false"
keystoreFile="${jboss.server.home.dir}/conf/.keystore"
keystorePass="123456" sslProtocol = "TLS" />
jboss默认有这些,但是注释了,如果没有就添加进去。需要注意下面几个属性值:
port是端口号,默认是8443。
keystoreFile="${jboss.server.home.dir}/conf/.keystore"是keystore文件路径。keystorePass是提示中输入的密码。
3、将系统部署后,启动,浏览器中输入https://localhost:443/projectName
理论上会提示证书不安全,点通过、继续、忽略之类的一个提示,就可以访问了。
Ⅸ 用java做一个httpClient 发送https 的get请求,需要证书验证的那种,求大神指点一下!

Ⅹ 如何处理与Apache HttpClient的无效SSL证书
如果是自己的私有证书,他本身不受信任的,而且可能您的SSL证书缺少了重要的文件,或者可以说不具备
浏览器信任条件,可以淘宝Gworg获取公网信任SSL证书。
