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:
<?php class HttpClientUtil { public function sendRequest($type = '', $url = '', $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, 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1'); if (substr($url, 0, 5) == 'https') { //自动判断是否是https提交 curl_setopt($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, ['Content-Type:application/json']); 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 ($curlInfo['http_code'] == 200) { //只有200状态才返回数据 return json_decode($result, true); } return false; } catch (\Exception $e) { throw new \Exception($e->getMessage()); } } public function createSign($data){ // 拼接 $dataStr = ''; foreach ($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);

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

A string is a sequence of characters, including letters, numbers, and symbols. This tutorial will learn how to calculate the number of vowels in a given string in PHP using different methods. The vowels in English are a, e, i, o, u, and they can be uppercase or lowercase. What is a vowel? Vowels are alphabetic characters that represent a specific pronunciation. There are five vowels in English, including uppercase and lowercase: a, e, i, o, u Example 1 Input: String = "Tutorialspoint" Output: 6 explain The vowels in the string "Tutorialspoint" are u, o, i, a, o, i.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
