如何正确准备'；HTTP重定向绑定'；使用Java的SAML请求？
有一些测试资源，例如如何正确准备'；HTTP重定向绑定'；使用Java的SAML请求？,java,single-sign-on,saml-2.0,shibboleth,Java,Single Sign On,Saml 2.0,Shibboleth,有一些测试资源，例如http://sometestresource.com我在http://sometestresource.com/Login我重定向到idP提供商：http://someidpprovoder.com/idp/authn/CommonLogin 嗅探器检测到重定向到https://someidpprovoder.com/idp/profile/SAML2/Redirect/SSO SAMLRequest=fZJda...D&RelayState=https%3A%2F

更新
- 我正在使用SP启动的Web SSO
- 基于的远程idP（在客户方面，关于它我什么都不知道。只是它是基于Shibboleth编写的）
- 您需要签名
在
authRequest.setSignature（签名）下的buildAuthnRequestObject
中
加
Signer
beingorg.opensaml.xml.signature.Signer
**更新**
使用SAMLMessageContext
和HTTPRedirectDeflateEncoder
public void doAuthenticationRedirect (HttpServletResponse response, final HttpSession currentSessiond) throws Exception {
/** Generate your authnrequest **/
AuthnRequest authnRequest = generateAuthnRequest();
/** Create an adapter from tomcat response servlet **/

/** Set entity end point**/
context.setPeerEntityEndpoint(endpointObject);
context.setOutboundSAMLMessage(authnRequest);
/** Sign this request **/
context.setOutboundSAMLMessageSigningCredential(getSigningCredential());

我认为这个问题是你的代码> EnCODRealEdStimeStase<代码>方法，既然你正在使用OpenSSAML，为什么不让它为你重定向< <代码> SAMLMessageContext < /代码>和<代码> HTTPRedirectDeflateEncoder < /代码>我更新了我的答案，对不起在工作的中间，但是我试图尽可能多地解释。
