PHP 调用第三方API接口、带参数跳转PHP

忘是亡心i 2024-04-18 16:43 88阅读 0赞

**前排说重点：关键方法在context.php文件里，有关于第三方接口调用的方法 function  api\_execute。 主要是在传递参数时，如果选择json格式传递，需要做相关处理； 然后在api\_execute方法里，也需要做参数的相关格式设置。**

首先是本地跑起一个java项目，模拟第三方接口的提供：

@PostMapping("/testLogin")
        public Map test(@RequestBody Map mapData) {
    
            Map<String, String> map = new HashMap<>();
            System.out.println("获取的值：" + mapData.toString());
            if (mapData.get("username").equals("admin") && mapData.get("pwd").equals("123456")) {
                map.put("code", "200");
                map.put("data", "login success");
            }else {
                map.put("code", "-1");
                map.put("data", "login fail");
            }
            return map;
        }

OK，接下来是PHP相关代码：

场景流程：  
buttonTest.php 模拟用户输入账户名和密码，点击按钮进行登录  
buttonTest.php 带着参数触发context.php，将参数传递过去  
context.php带着参数，调用方法去访问第三方接口API  
第三方接口API收到参数后，做登录校验处理，返回参数  
context.php 接收第三方接口API的参数，做逻辑处理（数据库写入等），带着结果参数跳转main.php

最后main.php对结果参数做处理  
  
  
buttonTest.php：

    <body>
    <form method="post" action="context.php">
    username: <input type="text" name="username">
    pwd: <input type="text" name="pwd">
    
    <input type="submit" value="login">
    </form>
    </bosy>
    </html>

context.php：

<?php
       $username=$_POST["username"]; //传递过来的username
       $pwd=$_POST["pwd"];           //传递过来的pwd
    
       $data_json = array("username" => $username, "pwd" => $pwd);  //将参数拼接成json                                                                  
       $data = json_encode($data_json);  //模拟调用接登录接口参数
    
       $url="http://localhost:8088/testLogin";//模拟登录接口
       $method="POST";
       $result= api_execute($method,$url,$data);//获取接口返回值
       $result_json= json_decode($result, true);
       $code=$result_json['code'];
       $data=$result_json['data'];
       $mysql_result=user_insert();//调用user插入方法，保存用户信息
       echo "CODE: $code <br>

       echo  "$mysql_result<br>AAA";
