Trouble with http.client.response

I'm making the following http.client.request call in an endpoint. <#assign response = http.client.request("https", "api.cognitive.microsofttranslator.com", "/translate?api-version=3.0&to=es&textTyp...

    Sounds like you're running into freemarker auto-escape. 

    https://freemarker.apache.org/docs/dgui_misc_autoescaping.html

    Basically you need to turn off autoescape or change outputformat to json. Also make sure your endpoint output format is set for application/json (this changes the content-type header in the endpoint response).

    You shouldn't need the ?replace after those changes.

Thanks! I finally got it working.

I surrounded the whole thing with 

<#noautoesc>
 
</#noautoesc>
 
I added .json() to my http.client.request
 
I was still getting an error because it said it was expecting a string, but it was a sequence instead. I think it didn't like that Microsoft's entire response was an array wrapped in [square brackets] instead of {curly braces}. So, I had to do this 
 
<#assign output = utils.json.toJson({"output":response.content})/>
 
Finally, it worked! The escaping is gone, and the weird double quotes are gone. I'm finally getting usable Json.
 
My final code.
 

 

<#noautoesc>
<#assign body = http.request.body />
<#--  <#assign body = "[{'Text':'<p class=\"testing\">Hello, what is your name?</p>'}]" />  -->

<#assign response = http.client.request("https", "api.cognitive.microsofttranslator.com", "/translate?api-version=3.0&to=es&textType=html")
    .header("Ocp-Apim-Subscription-Key", "My Key Here")
    .header("Ocp-Apim-Subscription-Region", "eastus")
    .header("Content-Type", "application/json")
    .body(body, "application/json")
    .json()
    .post() />

<#if response.hasError>
    ${response.error.message}
<#else>
    <#assign output = utils.json.toJson({"output":response.content})/>
    ${output}
</#if>

</#noautoesc>
