我在我的应用程序中使用游戏分析 (GameAnalytics.com)。对于不熟悉 GA 的人来说，它是一项免费的移动应用分析服务，例如 flurry。我需要一些 GameAnalytics 不会做的分析，这就是为什么我下载原始 json 事件数据，解析并将其存储在本地数据库中以供进一步处理。首先我认为每次手动下载数据都可以，但后来我意识到我很烦人，最好自动执行此操作。
我对 webdev、php 和 js 没有深入的了解，尽管多年来我主要将 php 用于实用程序和软件后端。
所以我使用了嗅探器，并且能够在 php 上使用 cookie 重现 GET 请求：
$rollingCurl = new RollingCurl();
$rollingCurl->get("https://query-2.gameanalytics.com/v1/games/$game_id/export?start=$from&end=$to&_=0521345345333644",
array(
"Host: query-2.gameanalytics.com",
"Connection: keep-alive",
"Accept: application/json, text/plain, */*",
"Origin: https://go.gameanalytics.com",
"User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/38.0.2125.122 YaBrowser/14.12.2125.10034 Safari/537.36",
"Authorization: priv-eyJhbGciOiAiSFMyNTYiLCAidHlwIjogIkpXVCJ9.eyJ0bblahblah....",
"Referer: https://go.gameanalytics.com/game/$game_id/settings/export-data",
"Accept-Encoding: gzip,deflate",
"Accept-Language: en;q=0.8"
)
);
但是这个请求使用了很快就会过期的cookies。所以唯一的方法是复制现有会话的cookie并将它们粘贴到php代码中，这很不方便。
我知道我必须打开 curl 会话，登录 gameanalytics.com，然后使用此会话下载我需要的数据。类似的方法成功用于： Download flurry event log using curl
但是由于某种原因我无法登录。它看起来像一些保护。主登录表单生成带有一些我在页面源中找不到的数字的目标 url。
go.gameanalytics.com/api/v1/public/login/basic?_= 0600650333334639
也许有一些已知的方案或解决方法？或者它与第一次加载时生成的 cookie 页面有某种联系？
当我使用这个号码通过 curl 登录时，它失败了：
$ch = curl_init('go.gameanalytics.com/api/v1/public/login/basic?_=0600650333334639');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/38.0.2125.122 YaBrowser/14.12.2125.10034 Safari/537.36");
curl_setopt($ch, CURLOPT_COOKIEFILE, null);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, '{"email":"$EMAIL","password":"$PASSWORD","remember":false}');
$data = curl_exec($ch);
//returns: {"errors": [{"msg": null, "type": null, "id": "405"}], "results": []}
以防万一这是来自浏览器的成功登录查询日志（当然所有敏感数据都已更改）：
