php curl post数据获取值形式引用url [英] php curl post data to get value form referred url
问题描述
我想向网页发送发布数据以获取价值。问题是，我想获得 abc.com 的数据形式。并且 abc.com 只有在用户来自 abc.com/时才打开 abc.com
也许它正在做一些会话或cookie来进行身份验证。我不知道。
我想做的是从abc.com获取数据。有没有办法通过curl来做呢？
我的PHP代码：
当你运行代码 c> c> =lang-php prettyprint-override> $ SearchBy =2;
$ AttorneySearchMode =Name;
$ LastName =Smith;
$ FirstName =William;
$ CaseStatusType =0;
$ SortBy =fileddate;
echo $ url ='https://www.clarkcountycourts.us/Anonymous/Search.aspx?ID=400&NodeID=101%2c103%2c104%2c105%2c500%2c600 ％2c601％2c602％2c603％2c604％2c605％2c606％2c607％2c608％2c609％2c610％2c611％2c612％2c613％2c614％2c615％2c616％2c617％2c618％2c619％2c699％2c700％2c701％2c702％2c703％2c704 ％2c705％2c706％2c707％2c708％2c709％2c710％2c711％2c712％2c713％2c714％2c715％2c716％2c717％2c718％2c719％2c720％2c721％2c722％2c723％2c724％2c725％2c726％2c727％2c728％2c729 ％2c730％2c731％2c797％2c798& NodeDesc = All + Courts';

我发现有3个问题阻止我请求其服务器上的网页：
- 需要在发布之前启用Cookie并提取一个网页
- 需要停用SSL检查（
CURLOPT_SSL_VERIFYPEER，CURLOPT_SSL_VERIFYHOST） - 请求中缺少一些必要的表单字段
在下面的示例中，我首先获取主搜索页面，然后重新使用相同的cURL句柄来发布表单。注意这是不完整的，您需要编写代码来填充剩余的表单字段。
//首先获取搜索页面cookies
$ url ='https://www.clarkcountycourts.us/Anonymous/Search.aspx?ID=400&NodeID=101%2c103%2c104%2c105%2c500%2c600%2c601%2c602%2c603%2c604 ％2c605％2c606％2c607％2c608％2c609％2c610％2c611％2c612％2c613％2c614％2c615％2c616％2c617％2c618％2c619％2c699％2c700％2c701％2c702％2c703％2c704％2c705％2c706％2c707％2c708 ％2c709％2c710％2c711％2c712％2c713％2c714％2c715％2c716％2c717％2c718％2c719％2c720％2c721％2c722％2c723％2c724％2c725％2c726％2c727％2c728％2c729％2c730％2c731％2c797％2c798& ; NodeDesc = All + Courts';

//执行第一个请求以建立cookie& referer

//现在做第二个请求

I want to send post data to a page to get value. The problem is that I want to get data form abc.com. And abc.com opens only if user comes to abc.com from abc.com/previous url.
Maybe it is is doing some session or cookies to authenticate. I have no idea.
What I want to do is get data from abc.com. Is there any way via curl to do it?
My php code:
When you run the code it says url has be moved as for this url you need to come from old refer url then it works in browser
$SearchBy = "2";
$AttorneySearchMode="Name";
$LastName= "Smith";
$FirstName= "William";
$CaseStatusType= "0";
$SortBy= "fileddate";
echo $url = 'https://www.clarkcountycourts.us/Anonymous/Search.aspx?ID=400&NodeID=101%2c103%2c104%2c105%2c500%2c600%2c601%2c602%2c603%2c604%2c605%2c606%2c607%2c608%2c609%2c610%2c611%2c612%2c613%2c614%2c615%2c616%2c617%2c618%2c619%2c699%2c700%2c701%2c702%2c703%2c704%2c705%2c706%2c707%2c708%2c709%2c710%2c711%2c712%2c713%2c714%2c715%2c716%2c717%2c718%2c719%2c720%2c721%2c722%2c723%2c724%2c725%2c726%2c727%2c728%2c729%2c730%2c731%2c797%2c798&NodeDesc=All+Courts';
//set POST variables
$fields = array(
'SearchBy' => urlencode($SearchBy),
'AttorneySearchMode' => urlencode($AttorneySearchMode),
'LastName' => urlencode($LastName),
'FirstName' => urlencode($FirstName),
'CaseStatusType' => urlencode($CaseStatusType),
'SortBy' => urlencode($SortBy),
);
$fields_string = "";
foreach ($fields as $key=>$value) {
$fields_string .= $key.'='.$value.'&';
}
rtrim($fields_string, '&');
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, true);
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
$result = curl_exec($ch);
curl_close($ch);
print_r($result);
Here is a starting point with some minor additions.
I found 3 issues that prevented me from requesting the page on their server:
- Need to enable cookies in cURL and fetch one page before posting
- Needed to disable SSL checks (
CURLOPT_SSL_VERIFYPEER,CURLOPT_SSL_VERIFYHOST) - Some necessary form fields are missing from the request
In the example below I first fetch the main search page, and then re-use the same cURL handle to post the form. Note this is incomplete, you will need to write code to populate the remaining form fields.
// first fetch search page to set cookies
$url = 'https://www.clarkcountycourts.us/Anonymous/Search.aspx?ID=400&NodeID=101%2c103%2c104%2c105%2c500%2c600%2c601%2c602%2c603%2c604%2c605%2c606%2c607%2c608%2c609%2c610%2c611%2c612%2c613%2c614%2c615%2c616%2c617%2c618%2c619%2c699%2c700%2c701%2c702%2c703%2c704%2c705%2c706%2c707%2c708%2c709%2c710%2c711%2c712%2c713%2c714%2c715%2c716%2c717%2c718%2c719%2c720%2c721%2c722%2c723%2c724%2c725%2c726%2c727%2c728%2c729%2c730%2c731%2c797%2c798&NodeDesc=All+Courts';
$ch = curl_init();
// needed to disable SSL checks for this site
curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,0);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,0);
// enable cookie handling (they aren't saved after cURL is closed)
curl_setopt($ch,CURLOPT_COOKIEFILE, '');
// debugging
curl_setopt($ch,CURLOPT_VERBOSE, 1);
curl_setopt($ch,CURLOPT_STDERR, fopen('php://output', 'w'));
// helpful options
curl_setopt($ch,CURLOPT_AUTOREFERER, true);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,1);
// set first URL
curl_setopt($ch,CURLOPT_URL, $url);
// execute first request to establish cookies & referer
$data = curl_exec($ch);
// TODO: extract hidden form fields/values from form
$fields_string = '...';
// now make second request
curl_setopt($ch,CURLOPT_POST, true);
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
$result = curl_exec($ch);
curl_close($ch);
var_dump($result);
See some of my other answers linked here which shows how to extract other form fields and do multiple requests. See also (cURL -- cookies and sessions) and (PHP Curl - Cookies problem)
