Mule中Twitter云连接器所需的输入

Question

我有一个带有custon过滤器的流，该过滤器可以工作（带有回声），但是如果我尝试使用Twitter云连接器，则会出现此错误

我认为该clout连接器没有收到所需的输入类型，但是我不确定，有什么帮助吗？

和custon过滤器类

package com.trabajosd;

import org.json.JSONArray;
import org.json.JSONObject;
import org.mule.api.MuleMessage;
import org.mule.api.routing.filter.Filter;

public class Filtro implements Filter{

    @Override
    public boolean accept(MuleMessage message) {
        try {
            String json=message.getPayloadAsString();
            JSONObject obj = new JSONObject(json);
            JSONArray lista = obj.getJSONArray("list");
            JSONObject elemento0 =lista.getJSONObject(0);
            JSONArray clima = elemento0.getJSONArray("weather");
            JSONObject prediccion = clima.getJSONObject(0);

            return prediccion.getString("main").equalsIgnoreCase("Clouds");

        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return false;
    }

}

Answer 1

Mule 3.6.x中的WWW身份验证标头标头似乎存在问题。

错误通常是“收到401响应，但不存在WWW-Authenticate标头”。 不知道您的情况为何是http响应403。

我尝试了一个基本的Twitter流，它在Mule 3.5上有效，但在3.6上不行。

报告的问题是：
