Steps for converting a set of data points into a format suitable for incorporation into an HTTP GET request

I'm working with a set of values:

var array = [10,11,12,13,14,15]

and I need to pass them as parameters in an http.get request in this format:

id=10&id=11&id=12&id=13&id=14&id=15

I initially tried the following approach:

var url = /myUrl;
var urlParam;
array.map(function(item) {
urlParam += '&id=' + item ;
return urlParam;
});

However, the resulting URL structure is incorrect:

INCORRECT

/myUrl&id=10&id=11&id=12&id=13&id=14&id=15

It should actually look like this:

/myUrl?id=10&id=11&id=12&id=13&id=14&id=15

when making the call using

$http.get('/myUrl' + urlParam);

Is there a more effective solution to achieve this?

Answer №1

It is highly recommended to utilize URLSearchParams for handling query strings in a URL.

var array = [10, 11, 12, 13, 14, 15];
const params = new URLSearchParams();

array.forEach(function(value) {
  params.append('id', value);
});

console.log('/myUrl?' + params.toString());

When dealing with the same key for URL query parameters, it's advisable to send them as one key with multiple values. You can use JSON.stringify() or directly send the array based on your implementation needs, but using JSON would offer a more organized approach.

var array = [10, 11, 12, 13, 14, 15];
const params = new URLSearchParams();
params.append('id', JSON.stringify(array));
console.log('/myUrl?' + params.toString());

Answer №2

To generate a URL with values from an array, you can assign each value to `id=${item}` and then combine them using the `&` symbol. Finally, attach this string to `/myurl?`.


<div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>const array = [10,11,12,13,14,15]
const url = '/myUrl?' + array.map((item) => `id=${item}`).join('&')
console.log(url)

Answer №3

According to the documentation provided by the Angular framework, there is a parameter called "params" that serves the purpose of passing query parameters.

All you have to do is include the "params" in the configuration when making your URL call.

If you visit this thread, you will find multiple examples on how to use this feature.

The "params" parameter takes a JSON object as input, so you can simply pass your array and it should work seamlessly!
