我想从一个网站上抓取信息来编译有关阿根廷机场的信息。该网站是 http://www.anac.gov.ar/anac/web/index.php/2/310/informacion-aeronautica/notam 。我试图让curl 获取通过ajax 查询访问的页面中的数据
<script type="text/javascript">
var lugares = document.getElementById("locations");
$(lugares).change(
function() {
$('.loading').show();
$('.ajaxbody').hide();
$.ajax(
{
url: "/notam/pib",
type: "POST",
dataType: "html",
data: {indicador: $(lugares).val()}
}).done(function(html) {
tabla = document.getElementById('pib');
$(tabla).find('table').remove();
$(tabla).append(html);
$('.loading').hide();
$('.ajaxbody').fadeIn('slow');
});
});
</script>
这就是我使用curl的方式curl -X POST -H“dataType:html”-d'/notam/p ib'-H“指标=TRE”http://www.anac.gov.ar/anac/web/index.php/2/310/informacio n-航空/notam
但是curl想要解析-H“indicador=TRE”，因为它是一个url，但它是在POST中发送的数据。
我看到页面使用wireshark发出的真实POST，这就是它看到的内容

最佳答案
你的curl命令令人困惑。特别是网址。所以我在命令中使用了一个虚拟 URL。
curl -X POST -H "dataType: html" -d "/notam/p ib" -H "indicador: TRUE" http://url/
我已将您的单引号替换为双引号，还调整了 -H 之前的空格。
关于javascript - 使用curl进行ajax查询，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/21867837/
