Ⅰ 怎麼給httpclient 配置https證書
你那個 SSLSocketFactory(ks) 是自己的類?
你有用過 KeyManager.init (...)? 和 TrustManager.init(...) ?
想要在連接建立過程上互動式的彈出確認對話框專來的話需要我們自屬己提供一個 KeyManager 和 TrustManager 的實現類,這有點復雜,你可以看一個 Sun 的 X509KeyManager 是怎麼做的,默認地情況下它是從自動搜索匹配的 subject ,我們需要用自己提供的方式彈出確認的過程還不是全自動,另外一個賬戶可能有多個數字證書,比如支付寶我們就有多個簽發時間不一樣的數字證書,在連接建立時 IE 會提示我們選擇其中的一個來使用,銀行的 U 盾在安裝多張數字證書時也會提示我們選擇其中一個對應到你正在使用的銀行卡號的那張證書。
Ⅱ 如何httpclient訪問https
很多情況下,需要通過程序抓取網頁或者調用介面獲取數據。使用apache的httpClient是一個最常用的開源的java第三方工具包。那麼如何訪問https的地址呢?
工具/原料
jdk
httpclent.jar
IDE(eg.Eclipse)或者文本編輯器 有一個就可以
方法/步驟
下載httpclient
網路一下:apache httpclient,還是看截圖吧

Ⅲ httpclient 支持https嗎
直接上代碼,做一個創建client的工具類
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();
}
下面就可以通過這個client訪問https的url地址
關鍵代碼:
//上面的工具類
CloseableHttpClient httpClient = HttpClientUtil.createSSLClientDefault();
HttpGet get = new HttpGet();
get.setURI(new URI("你的https://地址"));
httpClient.execute(get)
//...........後續操作
Ⅳ HttpClient 怎麼忽略證書驗證訪問https
您好,我來為您解答:
自定義一個SSLSocketFactory,忽略證書的驗證。
如果我的回答沒能幫助您,請繼續追問。
Ⅳ httpclient支持https嗎
支持,
默認情況下,如果你訪問的https站點頒發者證書存在於jre的cacerts中,直接用就可以;
如果你訪問的https站點不是內置頒發者:如12xx6那個XX網站的https。。。那就得費點功夫
簡單理解: 請用瀏覽器訪問那個https url,如果沒警告,一般情況下直接用就可的
Ⅵ 如何使用httpclient訪問雙向ssl認證的網站
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();
}
}
然後
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如何去支持無證書訪問https
項目里需要訪問其他介面,通過http/https協議。我們一般是用HttpClient類來實現具體的http/https協議介面的調用。
// 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();
}
以上代碼在通過普通的http協議是沒有問題的,但如果是https協議的話,就會有證書文件的要求了。一般情況下,是這樣去做的。
// 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");
}
於是,這里就需要事先生成一個.sis.cer的文件,生成這個文件的方法一般是先通過瀏覽器訪問https://,導出證書文件,再用JAVA keytool command 生成證書
# $JAVA_HOME/bin/keytool -import -file sis.cer -keystore .sis.cer
但這樣做,一比較麻煩,二來證書也有有效期,過了有效期之後,又需要重新生成一次證書。如果能夠避開生成證書文件的方式來使用https的話,就比較好了。
還好,在最近的項目里,我們終於找到了方法。
// 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)這個方法,看看這個方法是如何實現的。
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,調用了Security.setProperty( "ssl.SocketFactory.provider",
"com.tool.util.DummySSLSocketFactory");
那麼這個com.tool.util.DummySSLSocketFactory是這樣的:
訪問https 資源時,讓httpclient接受所有ssl證書,在weblogic等容器中很有用
代碼如下:
1. import java.io.IOException;

87. return socket;
88. }
89. }

91. //自定義私有類

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

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

}
return sslcontext;
}
private SSLContext getSSLContext() {

socket,
host,
port,
autoClose
);
}
public Socket createSocket(String host, int port) throws IOException,
UnknownHostException {
return getSSLContext().getSocketFactory().createSocket(
host,
port
然後按如下方式使用HttpClient
Protocol myhttps = new Protocol("https", new MySecureProtocolSocketFactory (), 443);
Protocol.registerProtocol("https", myhttps);
HttpClient httpclient=new HttpClient();
Ⅷ 請教httpclient訪問https,我的步驟錯哪裡了
首先是服務端如何支持https的問題,步驟如下。
1、生成服務端證書,cmd命令:
keytool -genkey -alias tomcat -keyalg RSA
或者
keytool -genkey -alias jboss -keyalg RSA
按照提示輸入一些信息,如果是本機調試,用戶名最好輸入localhost,否則會出現不匹配異常。
完成後,系統默認把文件放在我的文檔裡面,名字默認是.keystore。
把文件復制到jboss-5.1.0.GA\server\default\conf下面。
2、在jboss-5.1.0.GA\server\default\deploy\jbossweb.sar\打開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默認有這些,但是注釋了,如果沒有就添加進去。需要注意下面幾個屬性值:
port是埠號,默認是8443。
keystoreFile="${jboss.server.home.dir}/conf/.keystore"是keystore文件路徑。keystorePass是提示中輸入的密碼。
3、將系統部署後,啟動,瀏覽器中輸入https://localhost:443/projectName
理論上會提示證書不安全,點通過、繼續、忽略之類的一個提示,就可以訪問了。
Ⅸ 用java做一個httpClient 發送https 的get請求,需要證書驗證的那種,求大神指點一下!
你那個 SSLSocketFactory(ks) 是自己的類?
你有用過 KeyManager.init (...)? 和 TrustManager.init(...) ?
想要在連接建立過程上互動式的彈出確認對話框來的話需要我們自己提供一個 KeyManager 和 TrustManager 的實現類,這有點復雜,你可以看一個 Sun 的 X509KeyManager 是怎麼做的,默認地情況下它是從自動搜索匹配的 subject ,我們需要用自己提供的方式彈出確認的過程還不是全自動,另外一個賬戶可能有多個數字證書,比如支付寶我們就有多個簽發時間不一樣的數字證書,在連接建立時 IE 會提示我們選擇其中的一個來使用,銀行的 U 盾在安裝多張數字證書時也會提示我們選擇其中一個對應到你正在使用的銀行卡號的那張證書。
Ⅹ 如何處理與Apache HttpClient的無效SSL證書
如果是自己的私有證書,他本身不受信任的,而且可能您的SSL證書缺少了重要的文件,或者可以說不具備
瀏覽器信任條件,可以淘寶Gworg獲取公網信任SSL證書。
