我想用 JSON 制作一个数组，但我复制了同一篇文章。 我正在为 WordPress 使用 REST API JSON 插件

我希望有人可以帮助我，谢谢

最佳答案

您可以更改 fetchPost返回帖子列表，例如:

Future<List<Post>> fetchPosts() async {
  http.Response response =
      await http.get('http://**********:88/WordPress/wp-json/wp/v2/posts/');
  List responseJson = json.decode(response.body);
  return responseJson.map((m) => new Post.fromJson(m)).toList();
}

然后您可以使用 Future<List<Post>>像这样:

@override
Widget build(BuildContext context) {
  return new FutureBuilder<List<Post>>(
    future: fetchPosts(),
    builder: (context, snapshot) {
      if (!snapshot.hasData) return Container();
      List<Post> posts = snapshot.data;
      return new ListView(
        children: posts.map((post) => Text(post.title)).toList(),
      );
    },
  );
}

ListView获取子列表，就像 Column等等，因此您可以使用任何包含子列表的小部件
