Cipta kaedah REST API GET menggunakan berbilang penapis dalam PHP

Question

Saya mencipta kaedah REST API GET dalam php menggunakan id parameter. http://localhost:8012/REST-API/items/expenses?id=2. Ini berfungsi dengan baik, tetapi saya mahu menggunakan http://localhost:8012/REST-API/items/expenses?id=2&year=2022 untuk mendapatkan data. Saya baru mengenali php dan mencuba semua kemungkinan tetapi tidak mendapat respons yang betul. Di bawah ialah kod

Expenses.php dalam

/fail kelas

<?php
class Expenses{   
    private $expensesTable = "expenses";      
    public $id;
    public $month;
    private $amount;
    public $year;
    
    public function __construct($db){
        $this->conn = $db;
    }   

    function expenses(){    
        if($this->year) {
            $stmt = $this->conn->prepare("SELECT * FROM ".$this->expensesTable." WHERE year = ?");
            $stmt->bind_param("i", $this->year);                    
        } 
        else if($this->id) {
            $stmt = $this->conn->prepare("SELECT * FROM ".$this->expensesTable." WHERE id = ?");
            $stmt->bind_param("i", $this->id);                  
        }
        else if($this->id && $this->year) {
            $stmt = $this->conn->prepare("SELECT * FROM ".$this->expensesTable." WHERE id = ? AND year= ?");
            $stmt->bind_param("i", $this->id,$this->year);                  
        }

        else {
            $stmt = $this->conn->prepare("SELECT * FROM ".$this->expensesTable);        
        }       
        $stmt->execute();           
        $result = $stmt->get_result();      
        return $result; 
    }
}
?>

readexpenses.php

<?php
header("Access-Control-Allow-Origin: *");
header("Content-Type: application/json; charset=UTF-8");

include_once '../config/Database.php';
include_once '../class/Expenses.php';

$database = new Database();
$db = $database->getConnection();
 
$expenses = new Expenses($db);

$expenses->id = (isset($_GET['id']) && $_GET['id']) ? $_GET['id'] : '0';
$expenses->year = (isset($_GET['year']) && $_GET['year']) ? $_GET['year'] : '0';
$expenses->extra = (isset($_GET['month']) && $_GET['month']) ? $_GET['month'] : '0';

$result = $expenses->expenses();

if($result->num_rows > 0){    
    $itemRecords=array();
    $itemRecords["expenses"]=array(); 
    while ($expense = $result->fetch_assoc()) {     
        extract($expense); 
        $itemDetails=array(
            "id" => $id,
            "month" => $month,
            "amount" => $amount,
            "year" => $year
        ); 
       array_push($itemRecords["expenses"], $itemDetails);
    }    
    http_response_code(200);     
    echo json_encode($itemRecords);
}else{     
    http_response_code(404);     
    echo json_encode(
        array("message" => "No item found.")
    );
}

.htaccess

RewriteEngine On    # Turn on the rewriting engine
RewriteRule ^read$ read.php [NC,L]
RewriteRule ^read/([0-9_-]*)$ read.php?id= [NC,L]
RewriteRule ^create$ create.php [NC,L]
RewriteRule ^update$ update.php [NC,L]
RewriteRule ^delete$ delete.php [NC,L]
RewriteRule ^expenses$ readexpenses.php [NC,L]
RewriteRule ^expenses/([0-9_-]*)$ readexpenses.php?year= [NC,L]
RewriteRule ^expenses/([0-9_-]*)$ readexpenses.php?id= [NC,L]
RewriteRule ^expenses/([0-9_-]*)$ readexpenses.php?id=&year= [NC,L]

Answer 1

Seperti yang saya katakan dalam komen, tiga peraturan terakhirnya adalah salah:

RewriteRule ^expenses/([0-9_-]*)$ readexpenses.php?year= [NC,L]
RewriteRule ^expenses/([0-9_-]*)$ readexpenses.php?id= [NC,L]
RewriteRule ^expenses/([0-9_-]*)$ readexpenses.php?id=&year= [NC,L]

Apakah yang akan berlaku kepada URL ini? http://example.com/expenses/2012 如何检测这是 id 或 year?

Saya mengesyorkan menggunakan penyelesaian ini:

http://example.com/expenses/id/2012   -> readexpenses.php?id=2012
http://example.com/expenses/year/2022 -> readexpenses.php?year=2022
http://example.com/expenses/2012/2022 -> readexpenses.php?id=2012&year=2022

Jadi .htaccess failnya ialah: (baru menukar tiga peraturan terakhir)

RewriteEngine On    # Turn on the rewriting engine
RewriteRule ^read$ read.php [NC,L]
RewriteRule ^read/([0-9_-]*)$ read.php?id= [NC,L]
RewriteRule ^create$ create.php [NC,L]
RewriteRule ^update$ update.php [NC,L]
RewriteRule ^delete$ delete.php [NC,L]
RewriteRule ^expenses$ readexpenses.php [NC,L]
RewriteRule ^expenses/year/([0-9]+)$ readexpenses.php?year= [NC,L]
RewriteRule ^expenses/id/([0-9]+)$ readexpenses.php?id= [NC,L]
RewriteRule ^expenses/([0-9]+)/([0-9]+)$ readexpenses.php?id=&year= [NC,L]

Ujian dalam talian:

Saya telah mengujinya dan ia berfungsi dalam setiap kes id /年，id< /code> 和 年份 , di bawah anda boleh melihatnya melepasi url

Anda juga harus menukar syarat php anda

if ($this->id && $this->year) {
  //..
} else if ($this->id) {
  //..
} else if ($this->year) {
  //..
} else {
  //..
}

Tanpa perubahan ini, ia tidak akan mencapai masa id dan tahun ditetapkan
