Question

我正在尝试开发一个使用Google Pagespeedinsights API作为后端的应用程序。当我使用curl https://www.googleapis.com/pagespeedonline/v5/runPagespeed?url=desired url 命令为特定的URL运行pagespeedinsights时，我得到的是json数据作为响应。

   Sample JSON response
    {
     "captchaResult": "CAPTCHA_NOT_NEEDED",
     "kind": "pagespeedonline#result",

         },

         },
         {
          "min": 1000,
          "max": 2500,
          "proportion": 0.3111175327063521

       }
      },
      "overall_category": "SLOW",
      "initial_url": "https://jsonlint.com/"
     }

   I am doing it programatically.

String pythonScript =“ import os \ n” +“ os.system（\” curl https://www.googleapis.com/pagespeedonline/v5/runPagespeed?url=“ + pageSpeedMetrics.getCompanyUrl（）+”>“ + PYTHON_FILE_LOCATION + fileName +” \“）”; BufferedWriter out =新的BufferedWriter（新的FileWriter（PYTHON_FILE_LOCATION.concat（PAGESPEEDINSIGHT_PYTHON_FILE_NAME）））; out.write（pythonScript）; out.close（）; System.out.println（pythonScript）; 进程p = r.exec（“ python” + PYTHON_FILE_LOCATION.concat（PAGESPEEDINSIGHT_PYTHON_FILE_NAME）+“”）; p.waitFor（）;

JSONObject json =新的JSONObject（）; json.put（“ crux_loading_experience”，jsonPagespeedInsight.getJSONObject（“ loadingExperience”））;; json.put（“ crux_origin_loading_experience”，jsonPagespeedInsight.getJSONObject（“ originLoadingExperience”））;

但是当我使用 https://developers.google.com/speed/pagespeed/insights/ 在线进行操作时，我可以看到FCP和FID计时和百分比值，但是在json文件中却没有。它是如何产生的？在此先感谢!!!

如何从Google Pagespeedinsights api json数据中提取loadingExperience和originLoadingExperience时间和百分比？
