Angular2 - 无法使用查询中的“where”条件获取REST API

Question

I am working with Parse Server, and I am trying to fetch data using the REST API in my Angular2 application.

I am trying to fetch data according to a where condition, but I am not able to do so.

This is the code I am using:

  constructor(http) {
        var key = new URLSearchParams();
        this.http = http;
        this.disho = null;

        key.set('where', {"estTime":"5min"});
        this.http.get('https://parseapi.example.com/classes/Setto', { where : key }).subscribe(data => {
        this.disho = data.json().results;
        console.log(this.disho);
        });

      }

The above code ignore my where condition, and returns all the records.

However, the following code returns the right results when executed in terminal via cURL

curl -X GET \
-H "X-Parse-Application-Id: someKey" \
-H "X-Parse-REST-API-Key: someKey" \
-G \
--data-urlencode 'where={"estTime":"5min"}' \
https://parseapi.example.com/classes/Setto

Answer 1

Change { where : key } to { search : key }

Should work!

Answer 2

I think that there is a typo in your code. Single quotes are missing. You could try the following:

key.set('where', '{"estTime":"5min"}');
