The following PHP tutorial column will introduce to you an interesting thing about implementing PHP request simulation. I hope it will be helpful to everyone!

I earned 50 yuan by simply implementing PHP request simulation

An interesting thing happened this weekend: I saw someone in the group who needed assistance with PHP development , and promised to be paid. I solved the problem after self-recommendation, and received 50 yuan.

Next I will talk about the whole thing in detail.

I opened QQ after get off work on Saturday, and while browsing the group messages, I saw this sentence: "Is there anyone in the group who can write PHP code, for free." I immediately added his QQ and told him that I was doing PHP development and I could help.

I received his reply on Sunday morning. He gave me a document and asked me to see if it could be implemented. I browsed the entire document carefully and found that it was a third-party interface document. I told him to dock this kind of document. The interface is very simple. I wanted to know what his specific business was, and he told me that I just needed help to get through it. The following is a screenshot of our conversation:

An interesting thing about my request simulation using PHP!

Although the money he offered was not much, I happened to have nothing to do at the time, so I accepted the offer. I copied the code I wrote before, then changed it again, and it was adjusted quickly. I showed him a screenshot. , he sent me a 50 yuan red envelope after confirming that there was no problem. I also sent him the documents, and the whole thing was over.

The next thing I want to talk about is the technical issues behind this matter.

First of all, he understands PHP development. He encountered a problem during development. I don’t know if he was too lazy to search or because he didn’t find a solution. This problem is actually a small problem in PHP implementation of request simulation. .

Now I share the entire file code, hoping to be of some help to people who encounter the same problem. Implementation code:

<?php
class HttpClientUtil
{
    public function sendRequest($type = &#39;&#39;, $url = &#39;&#39;, $data = [], $timeout = 60)
    {
        try {
            $type = strtoupper($type);
            $curl = curl_init();
            curl_setopt($curl, CURLOPT_URL, $url);//设置请求链接
            curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);//不直接输出页面
            curl_setopt($curl, CURLOPT_HEADER, 0);//获取响应头向下
            curl_setopt($curl, CURLOPT_TIMEOUT, $timeout);   //请求超时时间,单位:秒
            curl_setopt($curl, CURLOPT_USERAGENT, &#39;Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1&#39;);
            if (substr($url, 0, 5) == &#39;https&#39;) { //自动判断是否是https提交
                curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);  // https请求 不验证证书和hosts
                curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
            }
            curl_setopt($curl, CURLOPT_HTTPHEADER, [&#39;Content-Type:application/json&#39;]);
            switch ($type) {
                case "GET" :
                    curl_setopt($curl, CURLOPT_HTTPGET, true);
                    break;
                case "POST":
                    curl_setopt($curl, CURLOPT_POST, true);
                    curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));
                    break;
                case "PUT" :
                    curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "PUT");
                    curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));
                    break;
                case "DELETE":
                    curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "DELETE");
                    curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));
                    break;
            }
            $result = curl_exec($curl);
            $err_code = curl_errno($curl);
            $curlInfo = curl_getinfo($curl);
            curl_close($curl);
            if ($err_code) {
                return false;
            }
            if ($curlInfo[&#39;http_code&#39;] == 200) { //只有200状态才返回数据
                return json_decode($result, true);
            }
            return false;
        } catch (\Exception $e) {
            throw new \Exception($e->getMessage());
        }
    }
    public function createSign($data){
        // 拼接
        $dataStr = &#39;&#39;;
        foreach ($data as $key=>$value){
            $dataStr.="{$key}={$value}&";
        }
        // 拼接商户密钥
        $dataStr.=&#39;access_token=***B8&#39;;
        // 加密
        $sign =strtoupper(MD5($dataStr));
        $data[&#39;sign&#39;]=$sign;
        return $data;
    }

$api = new HttpClientUtil();
