Php $ _SERVER [" REQUEST_METHOD"]总是返回get [英] Php $_SERVER["REQUEST_METHOD"] alway return get

问题描述

我在我的localhost中写了一些代码。

I'm writing some code in my localhost.

index.php：

   $task = null;

    $method = $_SERVER['REQUEST_METHOD'];

    var_dump($method);

    //initialize data
    HttpProtocol::init();

    if (empty($method))
        exitApp("unknown method");

    if ($method == HttpProtocol::get())
        $task = new WebhookVerifyTask();
    else if ($method == HttpProtocol::post())
        $task = new ProcessFacebookEventTask();
    if (is_null($task))
        exitApp("unknown method");

    $task->start();
    http_response_code(200);

如果我发送GET或POST请求无关紧要，$ method将始终为GET 。
尝试PUT或DELETE时 - 它会完美地改变..

it doesn't matter if I send a GET or POST request, the $method will always be GET. When trying PUT or DELETE - it changes perfectly..

什么可能导致$方法即使在POST时仍然是GET？

What could cause the $method to always be GET even when POST ?

UPDATE
显然当我将请求发送到localhost / path时 - 出现上述行为。如果我将它发送到localhost / path / - 帖子工作正常。

UPDATE apparently when i'm sending the request to localhost/path - the above behaviour occur. if i'm sending it to localhost/path/ - the post works perfectly.

您的更新也会回答您的问题。如果是/ path，但是没有这样的文件，Web服务器会自动将您重定向到/ path /。 - Janno

执行此重定向时 - 他没有完全使用所有请求数据和方法吗？

when it does this redirection - he does not do it completely with all the request data and methods ?

它不能。 Web服务器决定告诉客户端它应该尝试对另一个URL的另一个请求。 Web服务器使用 302 Found 状态代码和位置：http：// localhost / path / 标头进行响应。这会导致客户端向该新位置发出另一个HTTP请求，并且新请求将始终为 GET 请求。 POST 请求无法重定向。 （好吧，从理论上讲，它们可以使用 307临时重定向，但实际上并没有广泛支持。）

It cannot. The web server decides to tell the client that it should try another request to a different URL. The web server responds with a 302 Found status code and a Location: http://localhost/path/ header. This causes the client to make another HTTP request to that new location, and that new request will always be a GET request. POST requests cannot be redirected. (Well, theoretically they can be with a 307 Temporary Redirect, but in practice that is not widely supported.)

您需要直接向规范网址发出请求，以免导致重定向。

You need to make your request to the canonical URL directly so as to not cause a redirect.
