实现用户注册默认为贡献者

// 打开Register.php
// 网站根目录 /var/Widget/Register.php

// 找到 'group' => 'subscriber'

$dataStruct = [
    'name' => $this->request->name,
    'mail' => $this->request->mail,
    'screenName' => $this->request->name,
    'password' => $hasher->hashPassword($generatedPassword),
    'created' => $this->options->time,
    'group' => 'subscriber'
];

// 将 'group' => 'subscriber' 修改为 'group' => 'contributor'
// 示例
$dataStruct = [
    'name' => $this->request->name,
    'mail' => $this->request->mail,
    'screenName' => $this->request->name,
    'password' => $hasher->hashPassword($generatedPassword),
    'created' => $this->options->time,
    'group' => 'contributor'
];
