Utilize Javascript to access Django Rest Framework API and obtain a Token

Question

Utilize Javascript to access Django Rest Framework API and obtain a Token

I've successfully set up an API with Django Rest Framework that functions well when accessed through cURL, HTTPie, or the browsable API. The API utilizes token authentication, requiring initial credentials to obtain a token. To achieve this using HTTPie (or cURL), follow these steps:

http POST http://127.0.0.1:8000/api/v1/api-token-auth/ username="user1" password="testpassword"

This will yield a response like:

HTTP/1.0 200 OK
Allow: POST, OPTIONS
Content-Type: application/json
Date: Sun, 03 Sep 2017 16:57:38 GMT
Server: WSGIServer/0.2 CPython/3.6.1
X-Frame-Options: SAMEORIGIN

{
    "token": "fgfdgfdgfdgfdgd45345345lkjlj"
}

Following this, utilize the token for a GET/PUSH request as follows:

http --json POST http://127.0.0.1:8000/api/v1/test/ test_text="Testing" 'Authorization: Token fgfdgfdgfdgfdgd45345345lkjlj'

Despite conducting extensive Google searches, I have yet to find a definitive explanation of how to translate the above process into Javascript. Specifically, how does one (1) Pass credentials to acquire a token; (2) Retrieve the Token; (3) Utilize the token for GET and PUSH requests?

Ajax is definitely the way to go.

Start off your app with an ajax call:

var data = {username:'user',password:'password'}

$.ajax({
       type: 'POST',
       data: data,
       url: 'http://your_url',
       success: function(res){
               console.log(res)
               $.ajaxSetup({
                  headers: {
                    "token": res.token
                  }
               });
       },
       error: function(error) {
           callbackErr(error,self)
       }
   })

This method hasn't been tested, but the concept is to use an Ajax call to retrieve a token and save it to a header for all future ajax requests.

Then you can proceed with:

var data = {test_text="Testing"}
$.ajax({
           type: 'POST',
           data: data,
           url: 'http://127.0.0.1:8000/api/v1/test/',
           success: function(res){
                   console.log(res)  //response from api call.
                   });
           },
           error: function(error) {
               callbackErr(error,self)
           }
       })

Alternatively, you can try:

$.ajax({
           type: 'GET',
           url: 'http://127.0.0.1:8000/api/v1/ANOTHER_TES/',
           success: function(res){
                   console.log(res)  //response from api call.
                   });
           },
           error: function(error) {
               callbackErr(error,self)
           }
       })

Modify the type parameter of the call to suit your request type.

When making post, get, or any other URL calls, it is important to keep in mind that these are asynchronous calls. To maintain the program flow and ensure successful post requests, utilizing the promise feature of JavaScript is necessary. This will effectively make your post call synchronous.

var data = {username:'user',password:'password'}

$.ajax({
       type: 'POST',
       data: data,
       url: 'http://your_url',
       success: function(res){
               console.log(res)
               $.ajaxSetup({
                  headers: {
                    "token": res.token
                  }
               });
       },
       error: function(error) {
           callbackErr(error,self)
       }
   })

This code snippet will function correctly if used at the beginning of your program. However, it operates asynchronously. To synchronize it with your program, implementing a promise is essential. For the last part of your query, you should do the following...

$.ajax({
       type: 'GET',
       url: 'http://your_url' + "/token=" + your_token,
       success: function(res){
               console.log(res)
       },
       error: function(error) {
           callbackErr(error,self)
       }
   })
