使用Mojolicious和Mango生成RESTful API

本示例代码演示了如何使用Mojolicious和Mango生成RESTful API，这可以帮助我们快速构建可伸缩的Web应用程序。Mojolicious是一个现代化的Web开发框架，而Mango是Mojolicious的对象文档映射器。

use Mojolicious::Lite;
use Mango;
my $client = Mango->new('mongodb://localhost:27017/mydb');
my $collection = $client->db->collection('mycollection');
# 创建读取所有记录的路由
get '/api' => sub {
 my $c = shift;
 my $objects = $collection->find;
 $c->render(json => $objects->all)
};
# 创建读取单个记录的路由
get '/api/:id' => sub {
 my $c = shift;
 my $document = $collection->find_one({_id => Mango::BSON::ObjectID->new($c->param('id'))});
 $c->render(json => $document)
};
# 创建添加记录的路由
post '/api' => sub {
 my $c = shift;
 my $document = $collection->insert($c->req->json);
 $c->render(json => $document)
};
# 创建更新记录的路由
put '/api/:id' => sub {
 my $c = shift;
 my $document = $collection->update({_id => Mango::BSON::ObjectID->new($c->param('id'))}, $c->req->json);
 $c->render(json => $document)
};
# 创建删除记录的路由
del '/api/:id' => sub {
 my $c = shift;
 my $document = $collection->remove({_id => Mango::BSON::ObjectID->new($c->param('id'))});
 $c->rendered(204)
};
app->start;
