php - Laravel 5 中的 MethodNotAllowedHttpException

Question

路由.php

Route::post('deactivatecountry', array(
            'as'   => 'deactivatecountry', 
            'uses' => 'CountriesController@deactivateCountry'
));
Route::post('deactivatestate', array(
            'as'   => 'deactivatestate', 
            'uses' => 'StatesController@deactivateState'
));

Javascript

function deactivateCountry(country_id) {
    if (window.XMLHttpRequest) {
        xmlhttp = new XMLHttpRequest();
    } else {
        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    }
    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {}
    }
    xmlhttp.open("POST","deactivatecountry", true);
    xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    xmlhttp.send("country_id=" + country_id);
}

function deactivateState(state_id) {
    if (window.XMLHttpRequest) {
        xmlhttp = new XMLHttpRequest();
    } else {
        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    }
    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {}
    }

    xmlhttp.open("POST","deactivatestate", true);
    xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    xmlhttp.send("state_id=" + state_id);
}

当调用我的 javascript 中的 deactivateCountry 函数时，代码运行良好。它调用 CountriesController 中的 deactivateCountry 方法，并按预期停用该国家/地区。

但是当我调用 deactivateState 函数时，它会抛出 MethodNotAllowedHttpException，我不知道为什么。

国家和州的路线相同，功能相似，但一个在工作，另一个在不工作。

有人可以帮我解决这个问题吗？我已经坐了几个小时了，我无法弄清楚为什么会这样

这是我在调用 deactiveState 方法时遇到的错误

@MarcinNabiałek 和@lukasgeiter。感谢您花时间和耐心回答这个问题。我已经能够解决问题。我所做的更改是在 javascript

function deactivateCountry(country_id) {
    if (window.XMLHttpRequest) {
        xmlhttp = new XMLHttpRequest();
    } else {
        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    }
    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {}
    }
    xmlhttp.open("POST","/deactivatecountry", true);
    xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    xmlhttp.send("country_id=" + country_id);
}

function deactivateState(state_id) {
    if (window.XMLHttpRequest) {
        xmlhttp = new XMLHttpRequest();
    } else {
        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    }
    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {}
    }

    xmlhttp.open("POST","/deactivatestate", true);
    xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    xmlhttp.send("state_id=" + state_id);
}

我在路由前面加了一个/。所以在 xmlhttp.open 中，我将它从 xmlhttp.open("POST","deactivatestate", true); 更改为 xmlhttp.open("POST","/deactivatestate", true) ;

当我检查 xmlhttp 请求的 POST url 时，我到达了这个位置，我与我指定的不同，这就是 Laravel 假设它是 GET 请求而不是 POST 的原因。
