Php 如何使用CURL进行callrest

我第一次在curl中使用restapi。我创建了一个api.php，并使用curl和with post方法调用该文件。在第68行，我收到一个错误请求变量，发出通知，但没有通过方法post获得其值“登录”。这是我的主意

在api.php页面上的curl请求之后，rquest var值将被登录，我们将在rquest值的帮助下调用login函数

Htaccess是：

<IfModule mod_rewrite.c>
    RewriteEngine On

    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-s
    RewriteRule ^(.*)$ api.php?rquest=$1 [QSA,NC,L]

    RewriteCond %{REQUEST_FILENAME} -d
    RewriteRule ^(.*)$ api.php [QSA,NC,L]

    RewriteCond %{REQUEST_FILENAME} -s
    RewriteRule ^(.*)$ api.php [QSA,NC,L]   
</IfModule>

通知的可能重复是因为您试图访问$\u请求变量中未定义的索引。在访问变量之前，您应该首先通过isset或empty检查它是否存在，或者使用unrecommed@suppressor。
