java - struts2中的http post方法

Question

当我尝试通过 Advance REST 客户端(google chrome 插件)执行这个 alfresco webscript [http://localhost:8383/alfresco/service/get-order-info] 时，它运行顺利，但是当我尝试通过以下代码执行然后它在这一行给出错误 JSONObject jsonObject = (JSONObject) new JSONParser().parse(responseString);

public class ComplainMasterDaoImpl implements ComplainMasterDao
{

@Override
public ComplainMaster fetchComplainInfo(String orderId, String user) throws Exception
{
    // TODO Auto-generated method stub
    HttpClient httpClient = new DefaultHttpClient();
    HttpPost httpPost = new HttpPost("http://localhost:8383/alfresco/service/get-order-info");
    List<NameValuePair> formParams = new ArrayList<NameValuePair>();
    formParams.add(new BasicNameValuePair("orderId", orderId));
    UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(formParams, "UTF-8");
    httpPost.setEntity(formEntity);
    HttpResponse httpResponse = httpClient.execute(httpPost);
    HttpEntity httpEntity = httpResponse.getEntity();
    String responseString = IOUtils.toString(httpEntity.getContent(), "UTF-8");
    JSONObject jsonObject = (JSONObject) new JSONParser().parse(responseString);
    JSONObject resultJson = (JSONObject) jsonObject.get("result");

    System.out.println(resultJson.toString());
    return null;
}
}

当我调试它时，我得到了 resonseString，如 Apache Tomcat/6.0.29 - 错误报告

HTTP 状态 401 -

Answer 1

仔细检查您的描述文件。并检查您在开发 Web 脚本时要提供的身份验证级别。

在webscript desc.xml文件中，authentication(可选)是需要的认证级别；有效值为:

1. none:指定完全不需要身份验证
2. guest:指定至少需要guest身份验证
3. user:指定至少需要命名用户身份验证
4. admin:指定至少需要指定的管理员身份验证

注意:如果不指定，默认值为none

注意:可选的 runas 属性可用于强制以特定用户身份执行网络脚本。这只能为存储在 Java 类路径中的 Web 脚本指定。

更多详情请引用以下链接: http://wiki.alfresco.com/wiki/Web_Scripts

否则，如果您只想为经过身份验证的用户保留您的 web 脚本，那么您需要为从 struts 访问 web 脚本的用户传递所需的身份验证详细信息。但要确保用户必须在露天。

因此，在您的 fetchComplainInfo 方法中添加以下代码以进行基本身份验证:

String basic_auth = new String(Base64.encodeBase64((YOUR_USER_NAME+":"+YOUR_PASSWORD).getBytes()));
httpPost.addHeader("Authorization", "Basic " + basic_auth);

所以，你的方法将是这样的:

public class ComplainMasterDaoImpl implements ComplainMasterDao
{

@Override
public ComplainMaster fetchComplainInfo(String orderId, String user) throws Exception
{
    // TODO Auto-generated method stub
    HttpClient httpClient = new DefaultHttpClient();
    HttpPost httpPost = new HttpPost("http://localhost:8383/alfresco/service/get-order-    info");

    String basic_auth = new String(Base64.encodeBase64((YOUR_USER_NAME+":"+YOUR_PASSWORD).getBytes()));
    httpPost.addHeader("Authorization", "Basic " + basic_auth);

    List<NameValuePair> formParams = new ArrayList<NameValuePair>();
    formParams.add(new BasicNameValuePair("orderId", orderId));
    UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(formParams, "UTF-8");
    httpPost.setEntity(formEntity);
    HttpResponse httpResponse = httpClient.execute(httpPost);
    HttpEntity httpEntity = httpResponse.getEntity();
    String responseString = IOUtils.toString(httpEntity.getContent(), "UTF-8");
    JSONObject jsonObject = (JSONObject) new JSONParser().parse(responseString);
    JSONObject resultJson = (JSONObject) jsonObject.get("result");

    System.out.println(resultJson.toString());
    return null;
}
}
