Unirest PHP：使用库文件出错

Question

我从here下载了unirest库，并将其解压缩到我网站的文件夹中。我已将这段代码放在页面上：

<?php 
         require_once "/unirest-php-master/src/Unirest.php";
         $response = Unirest\Request::post("https://api4yaware-yaware-data.p.mashape.com/account/json/v2/getEmployeeLastActivity?access_key=&email=demo%2Beco%40yaware.com",
  array(
    "X-Mashape-Key" => "TSJbkryFpxmshZKbe1UxI0T9L0ddp1UFplVjsnSXjugPiVmxPd",
    "Content-Type" => "application/x-www-form-urlencoded",
    "Accept" => "text/plain"
  )
);
echo $response;
         ?>

我收到了这个错误：

  

解析错误：语法错误，意外＆＃39; [＆＃39;在   Y：\家\本地主机\ WWW \仪表板\ unirest-PHP主机的\ src \ Unirest \ Request.php   在第419行
