之前的获取QQ昵称的接口都会出现乱码的问题，最近看到了一个使用 form-data 的提交方式，我也不知道怎么来的，但是确实有用，就改成了PHP的了

function get_qq_nick($qqCode) {
    $curl = curl_init();
    curl_setopt_array($curl, [
        CURLOPT_URL => 'https://users.qzone.qq.com/fcg-bin/cgi_get_portrait.fcg?uins='.$qqCode,
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_ENCODING => '',
        CURLOPT_MAXREDIRS => 10,
        CURLOPT_TIMEOUT => 30,
        CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
        CURLOPT_CUSTOMREQUEST => 'GET',
        CURLOPT_POSTFIELDS => '------WebKitFormBoundaryYTwvlk5brGmyD3Mn',
        CURLOPT_HTTPHEADER => [
            'Content-Type: multipart/form-data; boundary=---011000010111000001101001',
        ],
    ]);
    $response = curl_exec($curl);
    $encode = mb_detect_encoding($response, array("ASCII",'UTF-8',"GB2312","GBK",'BIG5'));
    $response = mb_convert_encoding($response, 'UTF-8', $encode);
    $name = json_decode(substr($response, 17, -1), true);
    return $name[$qqCode][6]; 
}
