如何将查询参数添加到Dart http请求？

如何正确地将查询参数添加到Dart http get请求？在尝试将’？param1 = one& param2 = two’附加到我的网址时,我无法正确回应我的请求,但它在Postman中正常工作.这是我的代码的要点：

final String url = "https://www.myurl.com/api/v1/test/";
    String workingStringInPostman = "https://www.myurl.com/api/v1/test/123/?param1=one&param2=two";

    Map<String,String> qParams = {
     'param1': 'one','param2': 'two',};


   var res = await http
      .get(Uri.encodeFull("$url${widget.pk}/"),headers: {httpHeaders.authorizationHeader: "Token $token",httpHeaders.contentTypeHeader: "application/json"},);

${widget.pk}只是一个传递的整数值(请参阅workingStringInPostman变量中的值123.

如果需要Uri参数,qParams可以用于connivence.

一个代码示例将受到欢迎.

var queryParameters = {
  'param1': 'one',};
var uri =
    Uri.https('www.myurl.com','/api/v1/test/${widget.pk}',queryParameters);
var response = await http.get(uri,headers: {
  httpHeaders.authorizationHeader: 'Token $token',httpHeaders.contentTypeHeader: 'application/json',});
