Mojolicious - 无法解析RESTful中的JSON

Question

我不可能在Mojolicious中解析JSON.我更新了Mojolicious并在使用之前使用了代码,但不推荐使用JSON-> new.

my $json = Mojo::JSON->new;
my $user_request = $json->decode($c->req->body);
my $err = $json->error;

从教程中,我发现已经添加了$ self-> req-> json,但所有POST都会导致错误和非工作代码.

 curl -H "Content-Type: application/json" --data @body.json http://localhost:3000/checkaddress

而我的body.json看起来像这样

{
       'id': 1
}

这是我在Mojolicious中的RESTful代码

post '/checkaddress' => sub {
my $self = shift;
my $dump = $self->dumper($self->req->json);
};

控制台日志

[Sat Feb 20 08:23:27 2016] [debug] 200 OK (0.001688s, 592.417/s)
[Sat Feb 20 08:24:38 2016] [debug] POST "/checkaddress"
[Sat Feb 20 08:24:38 2016] [debug] Routing to a callback
[Sat Feb 20 08:24:38 2016] [debug] undef

调用$ self-> req-> body然后从Mojo :: JSON调用decode_json将导致

[error] Malformed JSON: Expected string while parsing object at line 1,  offset 5 at /home/aa/sempt2.pl line 15.

那么,现在如何正确解析JSON？

这与Mojolicious 6.25一起使用,是一个完整的例子:

package MyREST;
use Mojo::Base 'Mojolicious';

use Data::Dumper;

sub startup {
  my $app = shift;

  my $routes = $app->routes;

  $routes->post('/checkaddress' => sub {
    my $self = shift;
    my $data = $self->req->json;
    my $dump = $self->dumper($self->req->json);
    print STDERR $dump;
    $self->render(json => $data);
  });

}

为方便和可靠地测试小客户端脚本:

#!perl

use strict;
use warnings;

use Mojo::UserAgent;

my $ua = Mojo::UserAgent->new;

my $tx = $ua->post('http://localhost:3000/checkaddress' => json =>
  {
    'id'  => "1",
  }
);

此脚本可避免JSON编码问题.

更好的是,以Mojolicious风格编写测试.

我解决了!

{
   'id': 1
}

它需要被替换为

{
  "id": 1
}

然后可以使用

my $test = decode_json($self->req->body);
$test->{id};

而缩短的方式

my $test = $self->req->json;
$test->{id};

工作呢!

由于错误的json编码'',错误发生,需要"".希望它可以帮助某人.
