使用Cro或HTTP :: UserAgent时获取url的内容

Question

我想要得到的内容https://translate.google.cn,然而,Cro::HTTP::Client和HTTP::UserAgent刚刚stucks,并WWW获取内容,我不知道为什么.如果我更改$url为https://perl6.org,所有三个模块都可以正常工作:

my $url = "https://translate.google.cn";
use Cro::HTTP::Client;
my $resp = await Cro::HTTP::Client.new(
    headers => [
       User-agent => 'Cro'
   ]
).get($url);
say await $resp.body-text();



use HTTP::UserAgent;
my $ua = HTTP::UserAgent.new;
$ua.timeout = 30;
my $response = $ua.get($url);

if $response.is-success {
    say $response.content;
} else {
    die $response.status-line;
}
)

use WWW;
say get($url)

我错过了sonething吗？谢谢你的建议.

Answer 1

对我来说,HTTP::UserAgent工作和Cro::HTTP::Client卡住.如果您希望进一步调试,两个模块都有一个调试选项:

perl6 -MHTTP::UserAgent -e 'my $ua = HTTP::UserAgent.new(:debug); say $ua.get("https://translate.google.cn").content'

CRO_TRACE=1 perl6 -MCro::HTTP::Client -e 'my $ua = Cro::HTTP::Client.new(); say $ua.get("https://translate.google.cn").result.body-text.result'

WWW也适合我.令人惊讶的是,它适用于您,因为它受到支持HTTP::UserAgent(这对您不起作用).这是它的get方法,告诉你它如何使用HTTP::UserAgent:

sub get ($url, *%headers) is export(:DEFAULT, :extras) {
    CATCH { .fail }
    %headers<User-Agent> //= 'Rakudo WWW';
    with HTTP::UserAgent.new.get: $url, |%headers {
        .is-success or fail .&err;
        .decoded-content
    }
}
