guzzle 可以设置请求超时时间，还可以发送异步请求
Curl
// 可以设置自定义header头部
// 可以设置超时时间
// 可以自定义请求方法
// curl_exec 成功时返回true，失败时返回false ，CURLOPT_RETURNTRANSFER 被设置为true，则函数执行成功时返回执行的结果，失败时返回false
// 获取错误信息函数 curl_error() curl_errno() curl_getinfo();
// http get

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_URL, $url);
$res = curl_exec($ch);
curl_close($ch);
return $res;
}
// http post

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
}
$output = curl_exec($ch);
curl_close($ch);
return $output;
}
// post client request

ps:
表单get提交：Payload query string parameters, 参数拼接到请求的url后面 ： username=ddd&pwd=ddd
表单post提交 Payload form data， 表单post提交默认的Content-Type:application/x-www-form-urlencoded，参数也是拼接成username=ddd&pwd=ddd 来传输的
表单提交，带有附件的提交，设置 enctype="multipart/form-data"
- form-data multipart/form-data 文件上传表单类型
--header 'Content-Type: multipart/form-data; boundary=--------------------------299043408196458162695418' \
--form 'c="1"' \
--form 'd="2"'
- x-www-form-urlencoded application/x-www-form-urlencoded 表单提交文件的默认类型
--data-urlencode 'c=1' \
--data-urlencode 'd=2'
- json

curl retry
重试机制： 什么情况下重试?
请求失败curl返回为false,还是根据http status 是否为200，304 。。。还是匹配的内容里面是否有关键字
https://cloud.tencent.com/developer/article/1581200
https://www.yisu.com/zixun/344331.html
// retry ,retry-delay
....
$data_json = json_encode($data);
$result = null;
for ($i = 1; $i <= 3; $i++) {
$result = Curl::post($api, $data, $opt, $error_msg);
$curl_info = Curl::$curl_info;
// 这样判定重试的机制，是根据请求的接口网络不稳定
if ($curl_info['http_code'] === 0) {
sleep(1);
continue;
}
break;
}
...

// 下载图片检查是否失败。。 很多网站js会显示状态码304，使用到了缓存
in_array($curl_info['http_code'], array(200, 304)) && $res
