从 curl 响应中提取 HTTP body

Question

我使用包 WWW::Curl::Easy 进行 API 调用，这是我的示例代码：

use WWW::Curl::Easy;

my $curl = WWW::Curl::Easy->new();

$curl->setopt(CURLOPT_POST, 1);
$curl->setopt(CURLOPT_HEADER, 1);
$curl->setopt(CURLOPT_HTTPHEADER, ['Accept: text/xml; charset=utf-8', 'Content-Type:text/xml; charset=utf-8', 'SOAPAction: "importSheet"']);
$curl->setopt(CURLOPT_POSTFIELDS, $requestMessage);
$curl->setopt(CURLOPT_URL, $tom::{'setup'}{'api'}{'carrier'}{'url'});


my $response;
$curl->setopt(CURLOPT_WRITEDATA, $response);

main::_log(Dumper($curl));

my $ret = $curl->perform();

如您所见，我将响应保存到变量 $response 中，但我想知道仅提取该响应的 HTTP body 而不提取 headers 的最佳方法是什么和东西。

现在我的回复是这样的：

HTTP/1.1 500 Internal Server Error
Date: Fri, 26 Nov 2021 21:38:42 GMT
Content-Type: text/xml
Connection: keep-alive
Content-Length: 241
Set-Cookie: TS01972c9d=01a27f45ea407d6a9622e8d70528d3201676317364865a22da7d73be308d9e49021a872fbfe71877fbee80ce454071bc9a105a4e33; Path=/; Domain=.test.test.com

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Body><SOAP-ENV:Fault><faultcode>SOAP-ENV:Server</faultcode><faultstring>user_not_found</faultstring></SOAP-ENV:Fault></SOAP-ENV:Body></SOAP-ENV:Envelope>

但我只想得到 body 没有 headers 的响应，所以它应该是这样的：

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Body><SOAP-ENV:Fault><faultcode>SOAP-ENV:Server</faultcode><faultstring>user_not_found</faultstring></SOAP-ENV:Fault></SOAP-ENV:Body></SOAP-ENV:Envelope>

我试过类似的东西：

$response_content = HTTP::Response->parse("$response") ;
$response_content = $response_content->content;

但它仍然包含 headers。

Answer 1

您可以使用 $curl->setopt(CURLOPT_HEADERDATA, $head) 和 $curl->setopt(CURLOPT_FILE, $body) 为来自响应的 header 和 body 数据设置单独的目标。

Answer 2

what is the best way to extract only HTTP body of that response

简单删除

$curl->setopt(CURLOPT_HEADER, 1);

或改为

$curl->setopt(CURLOPT_HEADER, 0);

如果你也想要header，那么还要添加以下内容：

$self->setopt(CURLOPT_HEADERDATA, $head);

总计：

my $curl = WWW::Curl::Easy->new();

$curl->setopt(CURLOPT_POST,       1);
$curl->setopt(CURLOPT_URL,        ...);
$curl->setopt(CURLOPT_HTTPHEADER, ...);
$curl->setopt(CURLOPT_POSTFIELDS, ...);

# $curl->setopt(CURLOPT_HEADER, 0);  This is the default.
$curl->setopt(CURLOPT_WRITEDATA,  \my $body);   # If you want the body.
$curl->setopt(CURLOPT_HEADERDATA, \my $head);   # If you want the head.
