How to POST urlencoded form data with $http without jQuery?

👋 Hey there! So, you're new to AngularJS and eager to develop an application using just AngularJS. That's awesome! 🎉

One common problem you might encounter is making an AJAX call to the server side using $http from your Angular app. In particular, you want to send parameters in a urlencoded form data format. Let's walk through some possible solutions to this problem.

🔍 Understanding the Issue

In your code snippet, you've successfully made the $http POST request, but you relied on jQuery's $.param function to urlencode the data. However, you want to avoid using jQuery and instead find a pure AngularJS solution.

🌟 Solution 1: URLSearchParams API

One way to achieve urlencoding without jQuery is by using the URLSearchParams API, which is built into modern browsers. Here's how you can modify your code:

var params = new URLSearchParams();
params.set('username', $scope.userName);
params.set('password', $scope.password);

$http({
    method: "post",
    url: URL,
    headers: {'Content-Type': 'application/x-www-form-urlencoded'},
    data: params.toString()
}).then(function(response){
    console.log(response.data);
});

Using the URLSearchParams API, you can easily set the parameters and then convert them to a string using the toString() method. This way, you achieve the desired urlencoded form data without depending on jQuery.

🌟 Solution 2: Manual serialization

If your target browser doesn't support the URLSearchParams API, don't worry! You can still accomplish your goal by manually serializing the data. Here's how:

var data = 'username=' + encodeURIComponent($scope.userName) +
           '&password=' + encodeURIComponent($scope.password);

$http({
    method: "post",
    url: URL,
    headers: {'Content-Type': 'application/x-www-form-urlencoded'},
    data: data
}).then(function(response){
    console.log(response.data);
});

Here, encodeURIComponent() is used to ensure that the parameter values are properly escaped for URL transmission.

💡 Understanding the Differences and Choosing the Right Solution

Both solutions effectively send urlencoded form data with $http without relying on jQuery. However, the first solution using the URLSearchParams API is preferred when supported by the target browser, as it provides a cleaner and more elegant approach.

📣 Call-to-Action

Now that you have these solutions in your arsenal, feel free to experiment and find which one works best for your project.
