我正在尝试Hash::Ordered而不是Tie::IxHash,因为它似乎更快.

虽然Tie::IxHash工作正常,但我遇到了一些问题Hash::Ordered.关键是要对哈希值进行排序(在Perl中通常是随机的).

use Hash::Ordered;
use JSON::XS;
use Data::Dumper;

use strict;
use warnings;

my $json = JSON::XS->new;

my $oh = Hash::Ordered->new;
$oh->push('result' => { 'counter' => "123" }, 'number' => { 'num' => '55' });

my @r = $oh->as_list;

$json->pretty(1);
my $jsondata = $json->encode(\@r);
print Dumper $jsondata;

结果很奇怪:

 [
   "result",
   {
      "counter" : "123"
   },
   "number",
   {
      "num" : "55"
   }
]

这是一个工作示例Tie::IxHash,我试着得到相同的结果Hash::Ordered.

use Data::Dumper;
use Tie::IxHash;
use JSON::XS; …

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);
};

Google地图是否有平铺API来接收有关建筑物的元信息？

例如:HERE Maps提供了一个瓷砖API来获取有关建筑物的信息.但数据主要仅在可用的城市.请参阅:此处是Map Tile API.

HERE Map Tile API的响应如下所示:
