好的，所以我正在尝试使用 Apache HTTPClient 将数据发布到 JSF 页面。如果有人曾经使用过 Geoportal，那就是收割机创建页面。无论如何，我使用 get 请求来获取页面，然后使用包含所有必需参数的 post 请求，包括从 get 请求中解析出来的 JSF 视图状态参数。调用 POST 请求时，页面被返回，但没有执行任何操作，例如保存新的收割机。以下是我的代码，任何帮助将不胜感激。谢谢。

    HttpMethod getReq = new GetMethod(pageURI);
    getReq.addRequestHeader("Content-Type", "text/html");
    getReq.addRequestHeader("User-Agent","Mozilla/5.0 (Windows NT 6.1; WOW64; rv:14.0) Gecko/20100101 Firefox/14.0.1");
    getReq.addRequestHeader("Connection", "keep-alive");
    getReq.addRequestHeader("Cookie", "iPlanetDirectoryPro=" + token + "; JSESSIONID=" + sessionid);
    try {
        // Get the edit harvester page.
        int response = client.executeMethod(getReq);
        if(response != 200) {
            logError(responseObj, response + " error occured while trying to get the Harvester Edit page.");
            return responseObj;
        }
        String responseBody = new String(getReq.getResponseBody(), "UTF-8");
        getReq.releaseConnection();

        // Extract the View State value.
        int position = responseBody.indexOf("javax.faces.ViewState");
        if(position == -1) {
            logError(responseObj, "Unable to authenticate user. Please make sure your session has not expired.");
            return responseObj;
        }
        responseBody = responseBody.substring(position);
        int valPosition = responseBody.indexOf("value");
        String valString = responseBody.substring(valPosition + 7, valPosition + 60);
        facesValue = valString.substring(0, valString.indexOf("\""));
        System.out.println("Faces View: " + facesValue);
    }
    catch (HttpException e) {
        logError(responseObj, "Invalid HTTP retured while trying to get the Harvester Edit page.");
        return responseObj;
    }
    catch (IOException e) {
        logError(responseObj, "Unable to get the Harvester Edit page.");
        return responseObj;
    }

    // Build Post Request
    PostMethod postReq = new PostMethod(pageURI);
    postReq.addRequestHeader("Content-Type", "text/html");
    postReq.addRequestHeader("User-Agent","Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.0; .NET CLR 1.1.4322; .NET CLR 2.0.50215;)");
    postReq.addRequestHeader("Accept-Charset", "Chareset+\";q=0.7,*;q=0.7");
    postReq.addRequestHeader("Cookie", "iPlanetDirectoryPro=" + token + "; JSESSIONID=" + sessionid);
    String userDN = PropertiesService.getProperty("openldap.usersDN");
    NameValuePair data[] = {
            new NameValuePair("harvestCreate:hvSubmit", "Save"),
            new NameValuePair("javax.faces.ViewState", facesValue)
        // Note there are many more values here. I just removed them because they should serve no purpose.

    };
    postReq.setRequestBody(data);
    try {
        // Get the edit harvester page.
        int response = client.executeMethod(postReq);
        if(response != 200) {
            logError(responseObj, response + " error occured while trying to get the Harvester Edit page.");
            return responseObj;
        }
        String responseBody = new String(postReq.getResponseBody(), "UTF-8");
        postReq.releaseConnection();
    }
    catch (HttpException e) {
        logError(responseObj, "Invalid HTTP retured while trying to get the Harvester Edit page.");
        return responseObj;
    }
    catch (IOException e) {
        logError(responseObj, "Unable to get the Harvester Edit page.");
        return responseObj;
    }
