Answer 1

PUT 方法仅在您的表单方法是 POST 并且您添加值为 PUT 的 _method 输入字段时才有效。

<form method="post">
    <input type="hidden" name="_method" value="PUT">
</form>

Answer 2

不允许 PUT 请求，因为您正在使用 Route::post($uri, $callback)。

您需要将路由指定为 Route::put($uri, $callback) 或（如果您还需要匹配其他请求）：

Route::match(['post', 'put'], '/a', function () {
    // for post & put requests
});

Route::any('/a', function () {
    // for all methods
});

如评论和其他答案中所述，PUT 请求必须是 POST 具有附加参数 _method=PUT.

的请求

请参考：https://laravel.com/docs/5.2/routing#basic-routing

Answer 3

你也可以使用

    {{ method_field('PUT') }}

在您的表单中使用 method = post 。以便 method_field 将其转换为 put

然后在你的 routes.php

     Route::put(.....);

或

    Route::any(...);
