【问题描述】：

我正在为学校构建一个 Flutter 应用程序，其中列出了犬种。我想知道是否可以为谷歌搜索查询下拉“关于部分”。我正在使用颤振/飞镖，但我认为这个问题与语言无关，我只想知道它是否可能。这就是我所说的：

我想抓取“关于”标题下的段落。这可能吗？

【参考方案1】：

你必须使用谷歌的这个 API https://developers.google.com/knowledge-graph

【讨论】：

谢谢，现在我只需要弄清楚如何在 dart 中访问这些嵌套的 JSON 元素...

@Connor 欢迎您）使用 JSON，您可以从这里开始 - docs.flutter.dev/development/data-and-backend/json

【参考方案2】：

但是，您有很多方法可以做到这一点。您可以使用此 API 的一种方式称为 SerpApi

这将返回Json中的结果

只需注册此服务。并且使用http 包，您可以获得这样的结果

import 'package:http/http.dart' as http;

var url = Uri.parse('https://serpapi.com/search');
var query = "Samoyed" // Your query;

var response = await http.get(url + "?q=$query&google_domain=google.com&api_key=secret_api_key");

print(response.body);

你会得到
