Question

我正在尝试一个简单的Rest api，GET和POST方法可以工作，但是当我尝试测试显示PUT和DELETE Undefined Index错误并显示数据库没有更新时，我尝试输入数据通过form-data和raw以及x-www-form-urlencoded，但没什么
当我手动将数据输入代码而不是$_REQUEST时，它就可以正常工作这是我的代码：

<?php 
try{
    include 'connection.php';
    $method_name=$_SERVER["REQUEST_METHOD"];
    if($_SERVER["REQUEST_METHOD"])
    {

        switch ($method_name) 
        {
          case 'GET':
            $qry="SELECT * from product";
            $result=mysqli_query($conn, $qry);

            while ($row=mysqli_fetch_row($result))
            {
                $temp_cat[]=array("product_id"=>$row[0],"product_name"=>$row[1],"product_price"=>$row[2],"product_qty"=>$row[3]);
            }

            $data=array("status"=>"1","message"=>"success","result"=>$temp_cat);
            break;

          case 'POST':

            $name=$_REQUEST['product_name'];
            $price=$_REQUEST['product_price'];
            $qty=$_REQUEST['product_qty'];
            $qry="INSERT INTO product(product_name,product_price,product_qty) values('$name','$price','$qty')";
            if(mysqli_query($conn, $qry))
            {
                $data=array("status"=>"1","message"=>"success","result"=>"Product add successfully");
            }
            else{
                $data=array("status"=>"1","message"=>"success","result"=>"Something wrong!!!");
            }
            break;

          case 'PUT':
            $id=$_REQUEST['product_id'];
            $name=$_REQUEST['product_name'];
            $price=$_REQUEST['product_price'];
            $qty=$_REQUEST['product_qty'];
            $qry="UPDATE product SET product_name='".$name."', product_price='".$price."',product_qty='".$qty."' where product_id='".$id."' ";
            if(mysqli_query($conn, $qry))
            {
                $data=array("status"=>"1","message"=>"success","result"=>"Product Update successfully");
            }
            else{
                $data=array("status"=>"1","message"=>"success","result"=>"Something wrong!!!");
            }
            break;

          case 'DELETE':
            $id=$_REQUEST['product_id'];
            $qry="delete from product where product_id='".$id."'";
            if(mysqli_query($conn, $qry))
            {
                $data=array("status"=>"1","message"=>"success","result"=>"Product Update successfully");
            }
            else{
                $data=array("status"=>"1","message"=>"success","result"=>"Something wrong!!!");
            }
            break;
        }
        echo json_encode($data);
    }
    else{
        $data=array("status"=>"0","message"=>"Please enter proper request method !! ");
        echo json_encode($data);
    }

}
catch(Exception $e) {
     echo 'Caught exception: ',  $e->getMessage(), "\n";
}

请记住，我对此并不陌生，这实际上是我第一次使用它！

Answer 1

对于PUT和DELETE，您需要通过以下方式获取请求参数：

$requestParams = array();
parse_str(file_get_contents('php://input'), $requestParams);

然后，您可以使用$ _GET或$ _POST来访问值：

$requestParams['product_id']

希望这会有所帮助。

POST和GET在邮递员中有效，但PUT和DELETE不起作用
