Question

我正在使用LWP::UserAgent向网址发送请求。但是在回复的某个时候，我得到了不完整的XML回复。

代码

$args->{pua} = LWP::UserAgent->new();
$args->{header} = HTTP::Headers->new;
$args->{header}->header("Content-Type" => "text/xml", "SOAPAction" => $args->{soapaction});
$request = HTTP::Request->new( "POST", $args->{endpoint}, $args->{header}, $args->{xml});
$response = $args->{pua}->simple_request($request);
my $xmlResponse = $response->content;

在$xmlResponse的某个时候，我得到了不完整的回复。为什么会这样？

当LWP由于超时或其他读取错误而无法读取全身时，可能会返回不完整的响应。在这种情况下，$response->is_success将true而$response->code将为200，但响应标头将包含名为X-Died的特殊标头。所以你可以查看这个标题：

unless ($response->is_success) {
    die "Response failed: ", $response->status_line;
}

if ($response->header('X-Died')) {
    die "Response failed (internal): ", $response->header('X-Died');
}

LWP :: UserAgent返回不完整的2GB响应消息
