using json objects in URLSearchParams


Is it possible to somehow append json objects onto a URLSearchParams object?

So instead of:

urlSearchParams.append('search', 'person');

it's:

urlSearchParams.append({search: "person"});


My answer courtesy of Darshak Gajjar's answer

Can use json objects via this way:

let test_this = [{"search": "person"}, { search: "another person"}];
var json = JSON.stringify(test_this);
urlSearchParams.append("myobj", json);

return this.http.post(this.post_url, urlSearchParams, options) //options being your own RequestOptions

Solution

    Something like this might work urlSearchParams = Object.assign(urlSearchParams, {search: "person"});

    EDIT: Alternate solution using vanilla javascript. Also, I thought URLSearchParams was just a normal js object, but in fact you have to use get, set and append to access properties.

    var params = new URLSearchParams("a=apple&b=balloon");
    var parametersToAdd = {c: "car", d: "duck"};
    for(key in parametersToAdd)
      params.append(key, parametersToAdd[key]);
    
    console.log(params.get('c'));
    console.log(params.get('d'));
      

    EDIT bis: .append() supports to re-use the same key/parameter name, while .set() would have overwritten a previous value.
