Question

主 url 为 this，POST 数据为 [{"target":"nepaltour.info","max_crawl_pages":5}]，结果为

<块引用>

{version: 0.1.20210519, status_code: 20000, status_message: Ok., time: 0.1509 秒，成本：0.000625，tasks_count：1，tasks_error：0，tasks：[{id：05210936-2757-0216-0000-49826d093722，status_code：20100， status_message：任务已创建，时间：0.0154 秒，成本：0.000625， result_count: 0, 路径: [v3, on_page, task_post], 数据: {api: on_page, 功能：task_post，目标：nepaltour.info，max_crawl_pages：5}，结果：空}]}。

这是从 POST API 获取的 id:05210936-2757-0216-0000-49826d093722。现在我们需要来自 here 的目标 url 的摘要，它只给出：

<块引用>

{version: 0.1.20210519, status_code: 20000, status_message: Ok., 时间：0.1142 秒，成本：0，tasks_count：1，tasks_error：0，tasks： [{id: 05210936-2757-0216-0000-49826d093722, status_code: 20000, status_message：好的，时间：0.0470 秒，成本：0，result_count：1，路径：[v3，on_page，摘要，05210936-2757-0216-0000-49826d093722]，数据：{api：on_page，函数：摘要}，结果：[{crawl_progress: in_progress, domain_info: null, page_metrics: null, crawl_status: {max_crawl_pages: 5, pages_in_queue: 1, pages_crawled: 0}}]}]}

最终网址是 this.

    print('url $url');
    String username = 'adhikaritoban@gmail.com';
    String password = '7eda91fd91c15c5e';
    String basicAuth =
        'Basic ' + base64Encode(utf8.encode('$username:$password'));
    print(basicAuth);

    final response = await http.get(
      Uri.parse(url),
      headers: {
        "Content-Type": "application/json",
        "Authorization": basicAuth,
        "Accept": "application/json"
      },
    );
    if(response.statusCode == 200){

      final extractedData = json.decode(response.body) as Map<String, dynamic>;
      print("extra $extractedData");

      final _external =
      extractedData['tasks']['result']['page_metrics']['links_external'];
      print("ex $_external");
      final _internal =
      extractedData['tasks']['result']['page_metrics']['links_internal'];
      final _duplicateTitle =
      extractedData['tasks']['result']['page_metrics']['duplicate_title'];
      final _duplicateDescription = extractedData['tasks']['result']['page_metrics']
      ['duplicate_description'];
      final  _duplicateContent =
      extractedData['tasks']['result']['page_metrics']['duplicate_content'];
      final _brokenLinks =
      extractedData['tasks']['result']['page_metrics']['broken_links'];
      final _brokenResources =
      extractedData['tasks']['result']['page_metrics']['broken_resources'];
      final _onPageScore =
      extractedData['tasks']['result']['page_metrics']['onpage_score'];
      print('$_onPageScore');
    }else {
      print('FireGun');
    }

无法从颤振中的 dataforseo api 获得 page_metrics 响应。代码在flutter
