使用 HttpClient 4.1 获取查询字符串

Question

我正在从 HttpClient 3.0 迁移到 Httpclient 4.1 如何从 URL 中获取查询字符串。

client = new DefaultHttpClient();

client.getHostConfiguration().setHost( pro.getProperty( "host" ),
                Integer.parseInt( pro.getProperty( "port" ).trim() ),
                    pro.getProperty( "protocol" ) );
//client.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);

client.getCredentialsProvider().setCredentials(
        new AuthScope( pro.getProperty( "host" ),
            Integer.parseInt( pro.getProperty( "port" ).trim() ),
                pro.getProperty( "protocol" ) ),
        new UsernamePasswordCredentials( user, userpassword ) );

client.getParams().setBooleanParameter(ClientPNames.ALLOW_CIRCULAR_REDIRECTS, true );
authget = new HttpGet( pro.getProperty( "getparam" ) );
HttpResponse response = client.execute( authget );
HttpEntity entity = response.getEntity();

我应该在此处插入什么以使查询字符串与“&”相匹配。

StringTokenizer qryStrToken = new StringTokenizer(***Insert code for getting query string***,"&");

while (qryStrToken.hasMoreTokens()){
    String temp = qryStrToken.nextToken();
    if(temp.startsWith("SMAGENTNAME")){
        smAgentName = temp.substring(temp.indexOf("=")+1);
    }
}

Answer 1

使用HttpGet的getUri方法。

String uri = authGet.getURI();

Answer 2

URI 包含您的查询字符串，您可以通过以下方式获取：

URLEncodedUtils.parse(new URI(request.getRequestLine().getUri()),HTTP.UTF_8);
