Question

我正在提供这些数据 {id =＆＃34; 1＆＃34;，title =＆＃34; foo＆＃34;，imagedescription =＆＃34; bar＆＃34;}

这是我的PHP端点

<?php

// This will update a photo that has been edited
if (isset($_GET['id'], $_GET['title'], $_GET['imagedescription']))
{
$id=   $_GET['id'];
$title=  trim($_GET['title']);
$imagedescription=trim($_GET['imagedescription']);

require 'db_connect.php';

$update_query = "Update images Set title = {$title}, imagedescription = {$imagedescription} Where id={$id}";

    if($update = $db->query($update_query))
    {
        $response["success"] = 1;
        $response["message"] = "Photo successfully updated.";
        // echoing JSON response
        echo json_encode($response);
    } 
    else 
    {
        $response["failed"] = 0;
        $response["message"] = "Oops! An error occurred.";
        $response["sql"] = $update_query;

        // echoing JSON response
        echo json_encode($response);
    }

}
else
{
// required field is missing
$response["failed"] = 0;
$response["message"] = "Required field(s) is missing";

// echoing JSON response
echo json_encode($response);
}

?>

我刚刚在邮递员中获得{＆＃34;失败＆＃34;：0，＆＃34;消息＆＃34;：＆＃34;缺少必填字段＆＃34;}，成功回复200。

如何使用PHP从请求中获取数据？

这是Angular服务

(function () {
angular.module('app')
    .service('PhotosManager', ['$http', function($http) {

            this.getPhotos = function () {

                return $http.get("get_all_photos.php");
            };

            this.updatePhoto = function (id, data) {
                return $http.put("update_photo.php"+ id, data);

            };

    }]);

})();

我可以看到成功的回复请求方法：PUT 状态代码：200 OK

这很有效。首先读取已经放入的数据，然后json_decode它，最后你可以从数组中访问它。

<?php


$putfp = fopen('php://input', 'r');
$putdata = '';
while($data = fread($putfp, 1024))
$putdata .= $data;
fclose($putfp);


$data = json_decode($putdata, true);

// This will update a photo that has been edited
if (isset($data['id'], $data['title'], $data['imagedescription']))
{
$id=   $data['id'];
$title=  trim($data['title']);
$imagedescription=trim($data['imagedescription']);

require 'db_connect.php';

$update_query = "Update images Set title = '{$title}', imagedescription = '{$imagedescription}' Where id={$id}";

    if($update = $db->query($update_query))
    {
        $response["success"] = 1;
        $response["message"] = "Photo successfully updated.";
        // echoing JSON response
        echo json_encode($response);
    } 
    else 
    {
        $response["failed"] = 0;
        $response["message"] = "Oops! An error occurred.";
        $response["sql"] = $update_query;

        // echoing JSON response
        echo json_encode($response);
    }

}
else
{
// required field is missing
$response["failed"] = 0;
$response["message"] = "Required field(s) is missing";

// echoing JSON response
echo json_encode($response);
}

?>
