这是简单php中的一个非常简单的示例。
有2个文件 client.php 和 api.php
。我将两个文件放在相同的url：上
http://localhost:8888/，因此您必须将链接更改为您自己的url。（该文件可以在两个不同的服务器上）。
这只是一个例子，它非常快捷，肮脏，而且自从我完成php以来已经很长时间了。但这是一个api的想法。
client.php
<?phpif (isset($_GET["action"]) && isset($_GET["id"]) && $_GET["action"] == "get_user") // if the get parameter action is get_user and if the id is set, call the api to get the user information{ $user_info = file_get_contents('http://localhost:8888/api.php?action=get_user&id=' . $_GET["id"]); $user_info = json_depre($user_info, true); // THAT IS VERY QUICK AND DIRTY !!!!! ?> <table> <tr> <td>Name: </td><td> <?php echo $user_info["last_name"] ?></td> </tr> <tr> <td>First Name: </td><td> <?php echo $user_info["first_name"] ?></td> </tr> <tr> <td>Age: </td><td> <?php echo $user_info["age"] ?></td> </tr> </table> <a href="http://localhost:8888/client.php?action=get_userlist" alt="user list">Return to the user list</a> <?php}else // else take the user list{ $user_list = file_get_contents('http://localhost:8888/api.php?action=get_user_list'); $user_list = json_depre($user_list, true); // THAT IS VERY QUICK AND DIRTY !!!!! ?> <ul> <?php foreach ($user_list as $user): ?> <li> <a href=<?php echo "http://localhost:8888/client.php?action=get_user&id=" . $user["id"] ?> alt=<?php echo "user_" . $user_["id"] ?>><?php echo $user["name"] ?></a> </li> <?php endforeach; ?> </ul> <?php}?>api.php
<?php// This is the API to possibility show the user list, and show a specific user by action.function get_user_by_id($id){ $user_info = array(); // make a call in db. switch ($id){ case 1: $user_info = array("first_name" => "Marc", "last_name" => "Simon", "age" => 21); // let's say first_name, last_name, age break; case 2: $user_info = array("first_name" => "Frederic", "last_name" => "Zannetie", "age" => 24); break; case 3: $user_info = array("first_name" => "Laure", "last_name" => "Carbonnel", "age" => 45); break; } return $user_info;}function get_user_list(){ $user_list = array(array("id" => 1, "name" => "Simon"), array("id" => 2, "name" => "Zannetie"), array("id" => 3, "name" => "Carbonnel")); // call in db, here I make a list of 3 users. return $user_list;}$possible_url = array("get_user_list", "get_user");$value = "An error has occurred";if (isset($_GET["action"]) && in_array($_GET["action"], $possible_url)){ switch ($_GET["action"]) { case "get_user_list": $value = get_user_list(); break; case "get_user": if (isset($_GET["id"])) $value = get_user_by_id($_GET["id"]); else $value = "Missing argument"; break; }}exit(json_enpre($value));?>在此示例中，我没有对数据库进行任何调用，但是通常这是您应该执行的操作。您还应将“ file_get_contents”功能替换为“ curl”。
