I am trying to invoke a simple RESTFul API that POST username and password using WSO2 ESB, but i did not get response when trying to invoke it using postman:

the RESTFul API URL is: http://{REST service IP:port}/api/signup

the URL to call from ESB is http://{ESP IP:PORT}/api1/signup

the API Configuration i made in the WSO2 ESB is

<api xmlns="http://ws.apache.org/ns/synapse" name="API_TEST"   context="/api1">
  <resource methods="POST" url-mapping="/signup">
    <inSequence>
      <log/>
      <send>
        <endpoint>
          <address uri="http://< REST service IP:port>/api/signup"/>
        </endpoint>
      </send>
    </inSequence>
    <outSequence>
      <log/>
      <send/>
    </outSequence>
  </resource>

Answer 1

如果您在帖子正文中发送 json，则需要从客户端设置 Content-Type: application/json 标头。

Answer 2

添加以前的答案 -：对于GET请求，这工作正常。但是POST请求您需要为其余客户端指定 Content-Type:application/json 标头。

I Solved it : I edit the URI-Mapping tp "/" and edit the LOG mediators..

<api xmlns="http://ws.apache.org/ns/synapse" name="API_TEST"context="/api1">
   <resource methods="POST" url-mapping="/">
  <inSequence>
     <send>
        <endpoint>
           <address uri="http://{ESB IP:PORT}/api/signup"/>
        </endpoint>
     </send>
  </inSequence>
  <outSequence>
         <send/>
       </outSequence>
   </resource>
  </api>
