只是试图提交表单 [英] just trying to submit a form

问题描述

可能重复：

cURL：只是尝试下载页面

我尝试提交此表单，但未填写任何字段cURL。

I'm trying to submit this form without filling any field using cURL.

我试过这个：

<?php

//set POST variables
$url = 'http://www.tourism.verona.it/_vti_g1_srSf.aspx?rpstry=3_';

//open connection
$ch = curl_init();

//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_POST,0);

//execute post
$result = curl_exec($ch);

//echo $result;

//close connection
curl_close($ch);

但输出只是相同的页面（我预计在提交表单后显示的页面，

but the output is just the same page (I expected the page that is showed after submit the form and that contains a list of hotels).

推荐答案

我建议以下选项：

curl_setopt($ch,CURLOPT_POST, true);
curl_setopt($ch,CURLOPT_POSTFIELDS, "");
curl_setopt($ch,CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookie.txt"); //make sure apache is able to write
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt"); //make sure apache is able to write
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");


CURLOPT_POST - to make a POST request
CURLOPT_POSTFIELDS - to send POST data
CURLOPT_FOLLOWLOCATION - for dealing with redirect.

其他3适用于大多数网站，你最好使用cookies，它不工作。

the other 3 are useful with most of the websites and you better use cookies then trying to figure out why it doesn't work.
