Hi sachin 

 

If you are expecting JSON, have you tried using (vary the HTTP request as appropriate for your need)

 

<#assign resp = http.client.request("https", "api.test.com", "/context/path").body("param1=val1", "application/x-www-form-urlencoded").json().post() />
<#if resp.hasError>
Error!
<#else>
<#assign jsonResp = resp.content >
${resp.content}
</#if> 

Thanks,

    Thanks PaoloT 

     

    I tried the solution but it did not helped. I am getting freemarker error. Below is the error.

    { "error":"
    FreeMarker template error:
    Method public final lithium.coreapi.webui.template.models.HttpClientRequestTemplateModel lithium.coreapi.webui.template.models.HttpClientRequestTemplateModel.body(java.lang.String,java.lang.String) throws freemarker.template.TemplateModelException takes exactly 2 arguments, 1 was given.

    The failing instruction (FTL stack trace):

      Hi sachin 

       

      you need to access the actual values from a real response - the above was just mock code which you need to adapt.

       

      Try this for a working example - remember to whitelist ip.jsontest.com in the Admin settings.

       

      <#assign resp = http.client.request("http", "ip.jsontest.com", "/").json().get() />
<#if resp.hasError>
Error!
<#else>
<#assign jsonResp = resp.content >
${jsonResp.ip}
</#if>

       

      Hope it helps
