使用到的工具

composer require ixudra/curl

在 App\Http\Responses 创建一个新的文件 AjaxResp.php

  AjaxResp.php 

<?php

namespace App\Http\Responses;

class AjaxResp {

    public function __construct() {

        $params = func_get_args();

        foreach( $params as $param )

        {

            $this->{$param} = null;

        }

    }

    // 将对象转为 JSON 对象

    public function toJson()

    {

        $json = json_encode($this, JSON_UNESCAPED_UNICODE);

        return response()->make($json)->header('Content-Type', 'application/json; charset=UTF-8');

    }

    public $ret;

    public $msg;

}

创建一个的控制器 然后写入话不多说直接上码

<?php

namespace App\Http\Controllers;

use Illuminate\Routing\Controller as BaseController;

use App\Http\Responses\AjaxResp;

use App\Models\WxUser;

use Curl;
use Image;

class WeChatController extends BaseController
{
    public function avatarBridge() {
        set_time_limit(60);

        $resp = new AjaxResp();

        $headimgurl = request('headimgurl');

        if( !$headimgurl ) {
            $resp->ret = 1;
            $resp->msg = 'invalid headimgurl url';
            return $resp->toJson();
        }

        // 获取大图
        $headimgurl = substr($headimgurl, 0, strripos($headimgurl, '/')) . '/0';
        $filename = sha1($headimgurl);

        $ymd = date('Ymd');
        $uploadDir = public_path("/upload/avatar/$ymd");
        if( !is_dir($uploadDir) ) {
            @mkdir($uploadDir, 0777, true);
        }

        $fileuri = "/upload/avatar/$ymd/$filename.png";
        $filepath = public_path($fileuri);

        if( !file_exists($filepath) || filesize($filepath) < 8 ) {
            $response = Curl::to($headimgurl)
                ->withContentType('image/png')
                ->withHeader('Connection: close')
                ->download($filepath);
        }

        if( !file_exists($filepath) ) {
            $resp->ret = 3;
            $resp->msg = 'headimgurl download error';
            return $resp->toJson();
        }

        // 头像 base64
        $type = pathinfo($filepath, PATHINFO_EXTENSION);
        $avatarData = file_get_contents($filepath);

        $resp->ret = 0;
        $resp->msg = 'success';
        $resp->base64 = 'data:image/' . $type . ';base64,' . base64_encode($avatarData);

        return $resp->toJson();
    }

}
