An interesting thing about my request simulation using PHP!

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:

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:

getMessage()); } } public function createSign($data){ // 拼接 $dataStr = ''; foreach ($data as $key=>$value){ $dataStr.="{$key}={$value}&"; } // 拼接商户密钥 $dataStr.='access_token=***B8'; // 加密 $sign =strtoupper(MD5($dataStr)); $data['sign']=$sign; return $data; } } $api = new HttpClientUtil(); $url = 'http://***/order/pay'; $data=[ 'userName'=>'test', 'version'=>'2.0', 'cardName'=>'张三', 'cardNum'=>'20932402940189310293', 'openBank'=>'招商银行', 'amount'=>'10.00', 'outOrderId'=>'JD123123123', 'returnUrl'=>'/', ]; $res = $api->sendRequest('post',$url,$api->createSign($data)); print_r($res);
