PHP开发API供其他客户端调用的例子:
1、服务端注册接口
<?php
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'";
$query = mysql_query($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));
}
?>
2、 客户端调用例子:
<?php

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)));
?>
