Question

全部，
我正在使用Axis2 Web服务。这些服务捆绑为.aar file并部署在WSO2 Application Server(AS)中。我能够在Windows environment以及Linux environment中运行的WSO2 AS中部署生成的.aar。问题是，
当我尝试访问托管在两个环境（Windows和Linux）中的POST服务时，我是getting response in Windows while getting the following error in the Linux环境。

 ... 9 more.

以下是我给出的输入：

URI:  

     https://localhost:8243/services/MyService/postRequest  

Input XML:  

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://service.sample.vijay.com">
   <soapenv:Header/>
   <soapenv:Body>
      <ser:postRequest>
         <ser:paramOne>Hello</ser:paramOne>
         <ser:paramTwo>All</ser:paramTwo>
         <ser:paramThree>This is POST request</ser:paramThree>
      </ser:postRequest>
   </soapenv:Body>
</soapenv:Envelope>

当我尝试使用Windows machine（Chrome浏览器 - ＆gt; cREST插件）中的rest客户端访问上述服务时，它会返回我预期的结果。
但是当我在Linux environment中尝试使用相同URI的相同请求时（主机地址单独更改为Linux IP），最终出现上述错误（想知道可能是什么问题）。

Do I need to change any configuration in Linux machine or WSO2 Application Server in Linux machine?

注意：
当我将URI更改为https://localhost:8243/services/MyService时，它在Linux和Windows中都能正常工作。但我的要求是在URI中使用Web方法名称（/postRequest here）请帮我解决这个奇怪的问题提前致谢。

修改：

我的services.xml是：

<serviceGroup name="AxisServices">
    <service name="MyService">
        <description>
            Please Type your service description here
        </description>
        <messageReceivers>
            <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only"
                class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver"></messageReceiver>
            <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out"
                class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"></messageReceiver>
        </messageReceivers>
        <parameter name="ServiceClass" locked="false">com.vijay.sample.service.MyService</parameter>
    </service>

我的Java课程：

package com.vijay.sample.service;

public class MyService {

    public String postRequest(String paramOne, String paramTwo, String paramThree) {

        // Logic here
        return "Success";
    }
}

Answer 1

您可以尝试以下URI来访问服务

http://localhost:9763/services/MyService/postRequest

而不是

https://localhost:8243/services/MyService/postRequest

Axis2 Web服务POST请求在Linux中不起作用 - 参数数量错误
