Wp\\U remote的路径正确。这是我为向第三方注册新闻稿而编写的插件的一部分。基本上，您是在利用该公司的api，而不是使用wordpress。主要问题是，许多公司的api都不相似，因此在不了解更多与您交互的公司的情况下，您必须进行一些测试，或者看看是否可以从中获得公开的结果。

function html_form_code() {  // THIS IS THE FORM TO SEND COLLECT USER DATA TO SEND TO 3rd party.
    echo \'<form action="\' . esc_url( $_SERVER[\'REQUEST_URI\'] ) . \'" method="post">\';
    echo \'<p>\';
    echo \'Your Name (required) <br />\';
    echo \'<input type="text" name="cf-name" pattern="[a-zA-Z0-9 ]+" value="\' . ( isset( $_POST["cf-name"] ) ? esc_attr( $_POST["cf-name"] ) : \'\' ) . \'" size="40" />\';

    echo \'Your Email (required) <br />\';
    echo \'<input type="email" name="cf-email" value="\' . ( isset( $_POST["cf-email"] ) ? esc_attr( $_POST["cf-email"] ) : \'\' ) . \'" size="40" />\';
