Put a string from JSON into var

Question

I'm a Linux sysadmin with very little coding experience. I was asked to develop a demo RCS chatbot in nodejs that would echo back any message it gets. I'm surprised I even got as far as I did, and I only have one last thing to do. I'm really enjoying this project and I was hoping I could ask for some help for the last piece. I'm trying to create a variable OD and put the value of access_token

I have this part of my code:

request5(options5, function (error, responseOD) {
              if (error) throw new Error(error);
              console.log(responseOD.body); // <--------------------------- Third line
              var OD = responseOD.body.access_token;
              console.log(OD); // <------------------------------- Fifth line
              var ODtoken = "Bearer ".concat(OD);
              });

The third line (I've written "third line" in the code snippet) returns this:

      {
        "token_type": "Bearer",
            "access_token": "cbYAmA9iElLteoAQrj9GsDT2VrnD",
            "expires_in": "7776000"
      }

but for some reason, the fifth line (console.log(OD);, I've written "fifth line" in the code snippet) returns:

undefined

Does anyone know why the OD variable won't receive the access_token from the JSON response?

Huge thanks ahead!

You just want to parse that string body into a Javascript object using JSON.parse(string) function. In the end your code should look like this:

request5(options5, function (error, responseOD) {
    if (error) throw new Error(error);
    var bodyAsObject = JSON.parse(responseOD.body);
    var OD = bodyAsObject.access_token;
    var ODtoken = "Bearer ".concat(OD);
});
