Question

我使用Postman（在Chrome中）测试Slim调用，但无法弄清楚如何获取任何已发布的JSON数据。

我提交原始JSON：

{"name":"John Smith", "age":"30", "gender":"male"}

在标题

中使用Content-Type：application / json

通过POST到：

http://domain/api/v1/users/post/test/

每次尝试获取JSON数据都会产生致命错误（请参阅下面的代码注释）

<?php
require 'vendor/autoload.php';
$app = new \Slim\Slim();
$app->add(new \Slim\Middleware\ContentTypes());


$app->group('/api/v1', function () use ($app) {

    $app->group('/users/post', function () use ($app) {

        $app->post('/test/', function () {

                print_r($app->request->headers); //no errors, but no output?

                echo "Hello!"; // outputs just fine

        $data = $app->request()->params('name'); //Fatal error: Call to a member function request() on a non-object
                $data = $app->request->getBody(); //Fatal error: Call to a member function getBody() on a non-object
                $data = $app->request->post('name'); //Fatal error: Call to a member function post() on a non-object
                $data = $app->request()->post(); //Fatal error: Call to a member function request() on a non-object

                print_r($data);
                echo $data;

        });

    });

});

$app->run();
?>

我错过了什么？

谢谢！

Answer 1

确保将$app加入到最后一个嵌套路线中，如下所示：

// Pass through $app
$app->post('/test/', function () use ($app) {

你在其他任何地方都这样做，所以我假设你只是忽略了它。

Answer 2

你必须从请求中获取正文：

$ APP-＆GT;请求 - ＆GT; getBody（）;

http://docs.slimframework.com/request/body/

Answer 3

在Slim 3中，我在curl POST数据中使用了body的值，但它没有用，为了解决这个问题我已经使用了这个，身体是对象而不是字符串：

$app->post('/proxy', function($request, $response) {
    $data = $request->getBody()->getContents();
    $response->getBody()->write(post('http://example.com', $data));
});

您可以在docs

中检查身体上的更多方法

Answer 4

    //You did not pass the ($app) in your post route... so make it correct 
    $app->post('/test/', function () use ($app){
        //now if you want to get json data so please try following code instead of print_r($app->request->headers);
        $us=$app->request->getbody(); 

        //$us will get the json data now if you want to decode it and and want to get an array so try following..
        $ar=json_decode($us,true);
        //now you have $ar array of json data use it where you want..
    });

Answer 5

试试这个：

$app->post('/test/', function () use ($app){
        instead of print_r($app->request->headers);
        $ar=$app->request->getbody(); 

       to get an array so try following..
        $arry=json_decode($ar,true);

    });

无法通过Slim提交JSON POST数据
