PHP开发API接口代码分享

本文主要和大家分享php实现API接口的代码，实现用户的注册、登录、查询用户信息的功能，是学习PHP API开发的不错实例，希望能帮助到大家。

PHP API接口的服务端部分

代码示例：

<?php
/**
*三目
* PHP开发API接口 服务端

*/
require 'conn.php'; 
header('Content-Type:text/html;charset=utf-8'); 
 
$action = $_GET['action']; 
switch ($action) { 
 
    //注册会员 
    case"adduserinfo"; 
        $username = lib_replace_end_tag(trim($_GET['username'])); 
        $password2 = lib_replace_end_tag(trim($_GET['userpassword'])); 
        $password = md5("$password2" . ALL_PS); 
        $email = lib_replace_end_tag(trim($_GET['email'])); 
 
        if ($username == '' || $password2 == '' || $password == '') { 
            $res = urlencode("参数有误"); 
            exit(json_encode($res)); //有空信息 
        } 
 
        $sql = "select username from `member` where username='$username'"; 
        $query = mysql-query.html target=_blank class=infotextkey>mysql_query()($sql, $conn); 
        $count = mysql_num_rows($query); 
 
        if ($count > 0) { 
            exit(json_encode(1)); //返回1表示注册失败 
        } else { 
 
            $addsql = "insert into `member` (username,password,email) values ('$username','$password','$email')"; 
            mysql_query($addsql); 
            exit(json_encode(0)); //返回0表示注册成功 
        } 
        break; 
 
 
    //查询用户信息 
    case"selectuserinfo"; 
        $username = lib_replace_end_tag($_GET['username']); 
        $sql = "select id,username,nickname,mobile from `member` where username='$username'"; 
        $query = mysql_query($sql, $conn); 
        $row = mysql_fetch_array($query); 
        foreach ($row as $key => $v) { 
            $res[$key] = urlencode($v); 
        } 
        exit(json_encode($res)); 
        break;
    //会员登录 
    case"userlogin"; 
        $username = lib_replace_end_tag($_GET['username']); 
        $password2 = lib_replace_end_tag(trim($_GET['userpassword'])); 
        $password = md5("$password2" . ALL_PS); 
        $sqluser = "select id,username,password from `member` where username='" . $username . "' and password='" . $password . "'"; 
        $queryuser = mysql_query($sqluser); 
        $rowuser = mysql_fetch_array($queryuser); 
        if ($rowuser && is_array($rowuser) && !empty($rowuser)) { 
            if ($rowuser['username'] == $username && $rowuser['password'] == $password) { 
                if ($rowuser['password'] == $password) { 
                    $res = urlencode("登录成功"); 
                    exit(json_encode($res)); 
                } else { 
                    $res = urlencode("密码错误"); 
                    exit(json_encode($res)); 
                } 
            } else { 
                $res = urlencode("用户名不存在"); 
                exit(json_encode($res)); 
            } 
        } else { 
            $res = urlencode("用户名密码错误"); 
            exit(json_encode($res)); 
        } 
        /*
         * 0：表示登录成功，1：表示密码错误，2：用户名不存在，3：用户名密码错误
         */ 
        break; 
 
    default: 
        exit(json_encode(error)); 
  }
}

PHP API 客户端部分

代码示例：

<?php
/**
* PHP API接口 客户端
* edit: 办公用品
*/
header('Content-Type:text/html;charset=utf-8'); //避免

输出乱码 function httpPost($url, $parms) { $url = $url . $parms; if (($ch = curl_init($url)) == false) { throw new Exception(sprintf()("curl_init error for url %s.", $url)); } curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 600); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); if (is_array($parms)) { curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: multipart/form-data;')); } $postResult = @curl_exec($ch); $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); if ($postResult === false || $http_code != 200 || curl_errno($ch)) { $error = curl_error($ch); curl_close($ch); throw new Exception("HTTP POST FAILED:$error"); } else { // $postResult=str_replace()("\xEF\xBB\xBF", '', $postResult); switch (curl_getinfo($ch, CURLINFO_CONTENT_TYPE)) { case 'application/json': $postResult = json_decode()($postResult); break; } curl_close($ch); return $postResult; } } $postUrl = "http://pujia.test.com/api/server.php"; $p=$_GET['p']; if ($p =="selectuserinfo") { $username = $_GET['username']; $parms = "?action=selectuserinfo&username=" . $username . ""; } elseif ($p =="adduserinfo") { $username = $_GET['username']; $userpassword = $_GET['userpassword']; $parms = "?action=adduserinfo&username=" . $username . "&userpassword=" . $userpassword . ""; } elseif ($p =="userlogin") { $username = $_GET['username']; $userpassword = $_GET['userpassword']; $parms = "?action=userlogin&username=" . $username . "&userpassword=" . $userpassword . ""; } $res = httpPost($postUrl, $parms); //$parms $res = json_decode($res); print_r(urldecode(json_encode($res))); }
