java.net.MalformedURLException: no protocol: "localhost/uatpw/ActiveTransaction"?isx=E13F42EC5E38

从包含 localhost 的 url 读取数据时出现格式错误的 URL 异常。

其实我的程序如下

package bll.sap;

import java.net.MalformedURLException;

import utility.PropertyUtility;

public class GetActiveData 
{
    public static void main(String[] args) {

        String sapURL = "";

        try {


            sapURL = PropertyUtility.getSapURL();


            //Get Summary Data
            SapDataSync sapDataSync = new SapDataSync();

            //sapDataSync.readTransactionJsonFromUrl(sapURL+"?isx=false");
            sapDataSync.readTransactionJsonFromUrl(sapURL+"?isx=E13F42EC5E38");

            } 
        catch(MalformedURLException me)
        {
            me.printStackTrace();
        }   
        catch (Exception e) {
                e.printStackTrace();
        }
    }









}

首先，确保您已为您的请求设置了协议。

其次，确保String包含 URL 的 URL 是 URL 编码的。即 URL 没有任何空格和其他特殊字符 - 这些应该被编码（空格是 %20 等）。

鉴于满足上述两个条件，您的程序不应从java.net.URL类中抛出异常。

查看上面的异常，您只需设置协议 ( http://)，但请确保正确编码 URL 地址字符串，否则您会从程序的其他部分获得异常。

此外，添加http://到以下字符串也将导致MalformedURLException: "localhost/uatpw/ActiveTransaction"?isx=E13F42EC5E38因为您的 URL 将包含"需要编码的特殊字符（在这种情况下）。

要提供有效的 URL，您应该确保从 URL 的服务器和路径段区域中去除引号： localhost/uatpw/ActiveTransaction?isx=E13F42EC5E38. 对此http://进行准备将产生一个有效的 URL。

您缺少http://localhost 前面的协议（例如 ）。

格式良好的 URL 可以是http://localhost/uatpw/ActiveTransaction

这不是一个问题。你想做什么？

但除此之外，“localhost/uatpw/ActiveTransaction”不是有效的 URL。url 必须以协议（http、https、ftp 等）开头。

你应该尝试：

http://localhost/uatpw/ActiveTransaction
