Question

我正在尝试使用Mojo::Message::Response访问$res->body对象的正文，但我得到一个空字符串。

如果我$res->to_string我得到以下

HTTP/1.1 200 OK

如果我print dump $res->content我得到以下内容（为清晰起见省略了部分），我想要的内容明确地在buffer中：

do {
  my $a = bless({
    asset           => bless({ auto_upgrade => 1, start_range => 0 }, "Mojo::Asset::Memory"),
    auto_decompress => 1,
    auto_relax      => 1,
    auto_upgrade    => 1,
    body            => 2,
    buffer          => "the content I want is here and there is a lot of it",
    events          => { read => [sub { ... }] },
    ...
    header_size     => 1363,
    headers         => bless({
    ...
    }, "Mojo::Headers"),
    pre_buffer      => "",
    raw_size        => 3973,
    read            => 'fix',
    real_size       => 2610,
    size            => 0,
    state           => "finished",
  }, "Mojo::Content::Single");
  $a->{read} = $a->{events}{read}[0];
  $a;
}

但是$res->body返回一个空字符串。我怀疑它与size，real_size和内容被分块有关，但它是什么？

对curl -v执行相同操作会返回以下标题：

我发现我可以使用$res->content->leftovers获取内容 - 这是正确的方法吗？

为什么Mojo :: Message :: Response返回一个空体？
