我有一个本地laravel 5.7安装，我从php artisan开始使用php 7.1在Win7上进行服务。我使用默认的用户会话授权，但是它不起作用，因为请求标头的cookie部分已被剪切，因此无法识别会话cookie。
我检查了客户端发送的请求标头和服务器检索的标头。有时会收到完整的Cookie标头，有时只收到一部分。每次重新加载页面时，结果是否都正确地相符，但是在所有页面上都会发生错误。 如果我收到完整的cookie标头，则收到大约2300-2350时，大约有2600个字符。 我使用Laravel Telescope和纯PHP getallheaders函数观看了检索到的标头。结果是相同的。
由客户端发送并由服务器检索的标头的一个示例： 发送
