PHP和基本的RESTful服务; GET请求所有记录与一个记录 [英] PHP and basic RESTful services; GET requesting all records vs one record

问题描述

我的PHP类有一个涉及RESTful服务的项目，我们有这样一个基本服务：

  $ request = $ _SERVER [REQUEST_METHOD]; 
 switch（$ request）{
 case'GET'：
 $ user = $ acctReader-> read（$ _ GET [username]，$ _GET [password]）; 
 if（isset（$ _ GET [id]）&& $ user == true）{
 // echo方法在验证$ user是帐户后返回单个记录一个单独的表
} elseif（！isset（$ _ GET [id]&& $ user == true）{
 // echo方法从db 
返回所有记录} 
 case'POST'：
 case'PUT'：
 case'DELETE'：
 default 
} 
  

我正在让GET响应用户验证，因此如果他们输入了有效的用户名/密码但不显式请求一个单一的ID，他们应该看到所有的记录

这是我的HTML的一部分：

 < form action =TaskService.phpmethod =GET> 
< label for =username>用户名< / label> 
<输入类型=textname =usernameid =usernamerequired />< br />> 
< label for =pass字>密码< /标签> 
< input type =passwordname =passwordid =passwordrequired />< br /> 
< label for =id>任务ID< / label> 
< input type =textname =idid =idplaceholder =optional/> 
< input type =submitname =getTaskvalue =GET TASK/> 
< / form> 
  

我能够验证我的第一个条件（输入用户名，密码和id） ）它返回一个值。然而，当我没有传入id时，我无法让所有的记录都存在。
关于我应该在哪里进行更改的任何想法？

解决方案

即使它是空的， $ _ GET [id] 也会被设置。如果（！）（$ _GET [id]）&& $ user = $，您将不得不要求我们

  = true）{
 // echo方法在验证$ user是单独表中的帐户后返回单个记录
} else {
 // echo方法返回所有记录db 
} 
  

或

  if（isset（$ _GET [id]）&& $ _GET [id]！=''&& $ user == true）{
 // echo方法在验证$ user是一个单独表中的帐户之后从db返回单个记录
} else {
 // echo方法从db 
返回所有记录} 
  

但是要小心使用 empty（）当字段可能包含

$ ul
<0> 0（0作为一个整数）

0.0（0作为浮点数）

0（0作为字符串）

因为这些都被认为是空的

My PHP class has a project involving RESTful services where we have a basic service set up like this:

$request = $_SERVER["REQUEST_METHOD"];
switch($request) {
    case 'GET':
        $user = $acctReader->read($_GET["username"], $_GET["password"]);
        if (isset($_GET["id"]) && $user == true) {
            // echo method to return single record from db after validating that $user is an account in a separate table
        } elseif (!isset($_GET["id"] && $user == true) {
            // echo method to return ALL records from db
        }
    case 'POST':
    case 'PUT':
    case 'DELETE':
    default
}

I'm in the midst of having the GET to respond to user validation in such that if they enter in a valid username/password but do not explicitly request a single id, they should see all the records
Here's what part of my html looks like:

<form action="TaskService.php" method="GET">
        <label for="username">Username</label>
        <input type="text" name="username" id="username" required/><br />
        <label for="password">Password</label>
        <input type="password" name="password" id="password" required/><br />
        <label for="id">Task ID</label>
        <input type="text" name="id" id="id" placeholder="optional"/>
        <input type="submit" name="getTask" value="GET TASK"/>
</form>

I was able to verify that my first conditional (where the username, pw, and an id are entered) that it returns one value. However, I am having trouble with having it give me all records when I don't pass an id in.
Any ideas on where I should be making my changes?

解决方案

The $_GET["id"] will be SET even if it is empty. You will have to either us

if (!empty($_GET["id"]) && $user == true) {
    // echo method to return single record from db after validating that $user is an account in a separate table
} else {
    // echo method to return ALL records from db
}

Or

if (isset($_GET["id"]) && $_GET["id"] != '' && $user == true) {
    // echo method to return single record from db after validating that $user is an account in a separate table
} else {
    // echo method to return ALL records from db
}

But beware of using empty() when the field could contains

• 0 (0 as an integer)
• 0.0 (0 as a float)
• "0" (0 as a string)

as these are all considered as empty
