HttpClient使用SESSIONID模擬用戶發送請求

使用HttpClient版本 4.2.5

 準備一已登錄用戶的sessionid：

public static void main(String[] args) {

    String url = "http://10.10.10.90/urcweb/api/http.do?method=get_im_info";

    Map<String,String> header = new HashMap<String,String>();
    header.put("Cookie", "JSESSIONID=C1A34A2EC4C9423BB460E6F7005CA81E");
    System.out.println(httpGet(url,null,header));
}

/**
 * 發送 get 請求
 * @param url
 * @param encode
 * @param headers
 * @return
 */
public static String httpGet(String url,String encode,Map<String,String> headers){
    if(encode == null){
        encode = "utf-8";
    }
    String content = null;
    DefaultHttpClient httpclient = new DefaultHttpClient();
       HttpGet httpGet = new HttpGet(url);

       //設置 header
       Header headerss[] = buildHeader(headers);
       if(headerss != null && headerss.length > 0){
        httpGet.setHeaders(headerss);
       }
       HttpResponse http_response;
    try {
        http_response = httpclient.execute(httpGet);
        HttpEntity entity = http_response.getEntity();
        content = EntityUtils.toString(entity, encode);
    } catch (Exception e) {
        e.printStackTrace();
    }finally {
           httpGet.releaseConnection();
       }
       return content;
}

/**
 * 組裝請求頭
 * @param params
 * @return
 */
   public static Header[] buildHeader(Map<String,String> params){
    Header[] headers = null;
    if(params != null && params.size() > 0){
        headers = new BasicHeader[params.size()];
        int i  = 0;
        for (Map.Entry<String, String> entry:params.entrySet()) {
            headers[i] = new BasicHeader(entry.getKey(),entry.getValue());
            i++;
        }
    }
    return headers;
   }

 

測試結果：

成功模擬了該登錄用戶，如：輸出信息如下：

{"friends":[{"id":7,"gname":"我的好友","type":null},{"id":0,"gname":"未分組","gmember":[]}],"extinfo":null,"userinfo":{"uid":"PTADMIN","icon":null,"skill":"1","user_type":"9510","uname":"平臺運營者","userId":"PTADMIN"}}
