android - 如何在Dart/Flutter中将主体添加到GET请求？

Question

我正在尝试从需要主体与GET请求的API获得响应。它可以与POSTMAN一起正常工作，因为它允许我们将正文添加到GET请求中。但是如何使用dart添加GET请求？

Answer 1

首先，您需要在pubspec.yaml中添加此依赖项

dependencies:
  flutter:
    sdk: flutter

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  http: ^0.11.3+16

以下是Flutter中调用API的代码段。

const baseUrl = "https://jsonplaceholder.typicode.com";

class NetworkApi {
  static Future getUsers() {
    var url = baseUrl + "/users";
    return http.get(url);
  }

  static Future getImages(){
    return http.post('http://xyz.in/api.php',body: {
      "parameter" : "value"
    });
  }
}

下面是dart类中的API调用。

getImages(){
    NetworkApi.getImages().then((response){
      setState(() {
          print("Response Status");
          print("Response : " + response.body);
          var data = json.decode(response.body);
          var imagesData = data["data"] as List;
//          images = list.map((model) => Data.fromJson(model)).toList();
        images = imagesData.map<Data>((json) => Data.fromJson(json)).toList();
          print("Images : " + images.length.toString());
      });
    });
  }
