guzzle cURL error 77: error set ting certificate verify locations

在sf 看到这篇文章 https://segmentfault.com/a/119000000514206... 自己测试了下，报错
curl: (60) SSL certificate : unable to get local issuer certificate
于是 使用 $client->setDefaultOption('verify', false); 类似 curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);，然后提示

$ php artisan guzzle

In Client.php line 128:

  Type error: Argument 3 passed to GuzzleHttp\Client::request() must be of th
  e type array, boolean given

于是去掉 $client->setDefaultOption('verify', false); 继续报错 cURL error 77: error set ting certificate verify locations
在 sf 上搜到答案 https://stackoverflow.com/questions/246116...

下载文件 https://curl.haxx.se/ca/cacert.pem 加入 php.ini curl.cainfo="/path/to/downloaded/cacert.pem" 注意使用绝对路径

先创建一个 command 见文档 Artisan 命令行 具体代码

<?php

    public function handle()
    {
        $client = new Client();
        // $client->setDefaultOption('verify', false);
        $requests = function ($total) use ($client) {
            foreach ($this->users as $key => $user) {
                $uri = 'https://api.github.com/users/' . $user;
                yield function() use ($client, $uri) {

                };
            }
        };
        $pool = new Pool($client, $requests($this->totalPageCount), [
            'concurrency' => $this->concurrency,

                $this->countedAndCheckEnded();

            'rejected' => function ($reason, $index){

               dump("rejected reason: " . $reason );
                $this->countedAndCheckEnded();
            },
        ]);

        // 开始发送请求
        $promise = $pool->promise();
        $promise->wait();
    }

    public function countedAndCheckEnded()
    {
        if ($this->counter < $this->totalPageCount){
            $this->counter++;
            return;

        dump("done");
    }
