我正在使用jquery從我正在構建的Mojolicious :: Lite API中獲取一些數據。但我無法通過ajax從API接收任何數據。我可以通過curl獲取數據。 更新：我可以在同一個域上通過ajax獲取數據。這是一個CORS問題。CORS：總是通過jQuery.ajax得到Mojolicious :: Lite的空響應
這裏是我的客戶端代碼：
$.ajax({
type: 'POST',
url: 'http://localhost:3000/path',
data: JSON.stringify({ foo: 'foo', bar: 'bar' }),
dataType: 'json',
contentType: 'application/json',
beforeSend: function(xhr){
xhr.setRequestHeader('Accept', 'application/json');
}
});
這裏的API代碼：
#!/usr/bin/perl -w
use Mojolicious::Lite;
use strict;
options '*' => sub {
my $self = shift;
$self->res->headers->header('Access-Control-Allow-Origin'=> 'http://localhost:7000');
$self->res->headers->header('Access-Control-Allow-Credentials' => 'true');
$self->res->headers->header('Access-Control-Allow-Methods' => 'GET, OPTIONS, POST, DELETE, PUT');
$self->res->headers->header('Access-Control-Allow-Headers' => 'Content-Type, X-CSRF-Token');
$self->res->headers->header('Access-Control-Max-Age' => '1728000');
$self->respond_to(any => { data => '', status => 200 });
};
post '/path' => sub {
return $_[0]->render(json => {hello => "world"});
};
app->start;
這裏是所有的請求頭和數據：

不知道問題出在我的JS或Perl代碼上。 更新：可能在JS代碼上。 更新：
CORS似乎沒問題。
