How to fetch api data by passing variables (parameters)?

问题

I am fetching api data for sports player for which I need to pass unique player id. Currently, I have to pass pid manually which fetches only one player's data at a time. But I would like to fetch multiple players data and display it in listView.

API endpoint is: https://cricapi.com/api/playerStats?apikey=&pid=0000.

I am able to parse above url, fetch it's result and display in UI properly, but I want to fetch multiple players data and not just one.

Code to fetch api:

FetchJson() async {
  var response = await http.get('https://cricapi.com/api/playerStats? 
    apikey=&pid=1111');

  if (response.statusCode == 200) {
    String responseBody = response.body;
    var responseJson = jsonDecode(responseBody);
    name = responseJson['name'];
    playingRole = responseJson['playingRole'];
    battingStyle = responseJson['battingStyle'];
    country = responseJson['country'];
    imageURL = responseJson['imageURL'];

Json snippet is:

{ "pid": 1111, "country": "Australia", "profile": "\n\n blah", "imageURL": "https://www.cricapi.com/playerpic/1111.jpg",

What I am trying to achieve is, to display multiple players profile dynamically instead of passing hardcoded pid in the code, so that the UI will display multiple players in listview.

How to pass different pid dynamically in the url endpoint ?

回答1:

By using String interpolation and receiving the id as parameter. You can read more about it here.

FetchJson(int playerId) async {
  var response = await http.get('https://cricapi.com/api/playerStats? 
    apikey=&pid=$playerId');

  if (response.statusCode == 200) {
    String responseBody = response.body;
    var responseJson = jsonDecode(responseBody);
    name = responseJson['name'];
    playingRole = responseJson['playingRole'];
    battingStyle = responseJson['battingStyle'];
    country = responseJson['country'];
    imageURL = responseJson['imageURL'];
