【问题描述】：

flutter中的dio包如何在这段代码中加入base-url与url和apikey。我对 dio 包的工作有点困惑，有人可以帮帮我吗

如果我有这样的网址

BaseURL = "https://newsapi.org/"
apkikey = "256c198308134b578e338737a895"
url= "v2/top-headlines?country=us"

dio包如何加入上面三个组件，产生如下所示的这种url

https://newsapi.org/v2/top-headlines?country=us&apikey=256c198308134b578e338737a895

任何帮助将不胜感激

【参考方案1】：

类似的东西，ArticleResponse 是模型

BaseURL = "https://newsapi.org/v2/"
getTopHeadLinesUrl = "$BaseURL/top-headlines";
apkikey = "256c198308134b578e338737a895"

Future<ArticleResponse> getTopHeadlines() async 
    var params = "apiKey": apikey, "country": "us";
    try 
      Response response = await _dio.get(getTopHeadLinesUrl, queryParameters: params);
      return ArticleResponse.fromJson(response.data);
     catch (e) 
      return ArticleResponse.withError(e.toString());
    
  

Example:
    "https://newsapi.org/v2/top-headlines?country=us&apiKey=509ea7c380274d5b9ae18c7a3fe9af7c"
