【问题描述】：

我正在输入这些数据 {id="1", title="foo", imagedescription="bar"}

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 Postman 中收到 {"failed":0,"message":"Required field(s) is missing"} 和 200 成功响应。

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);

            };

    }]);

})();

我可以看到成功的响应请求方法：PUT 状态码：200 OK

How do I access PHP REST API PUT data on the server side?的可能重复
您正在输入这些数据{id="1", title="foo", imagedescription="bar"} 知道了。但是来自 ajax 或来自 rest 客户端，它是 GET 还是 POST？
$http.put("update_photo.php"+ id, data);
包含 JS 部分，这样会更有帮助

标签： php rest put

【解决方案1】：

这行得通。先读取已经放入的数据，然后json_decode，最后就可以从数组中访问了。

<?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);
}

?>
