当获取URL重定向时，File_get_contents()不起作用 [英] File_get_contents() not working when the get url redirects

问题描述

我正在使用的功能是:

function http_post ($url, $data)
{
$data_url = http_build_query ($data);
$data_len = strlen ($data_url);
date_default_timezone_set('America/New_York');

return array ('content'=>file_get_contents ($url, false
    , stream_context_create (array ('http'=>array (
    'method'=>'GET', 
    'header'=>"Connection: close\r\nContent-Length: $data_len\r\nContent-type: application/x-www-form-urlencoded\r\n", 
    'content'=>$data_url
    )))), 
    'headers'=>$http_response_header
    );
}

电话是:

http_post('http://www.wunderground.com/cgi-bin/findweather/getForecast/', array('airportorwmo'=>'query','historytype'=>'DailyHistory','backurl'=>"/history/index.html",'code'=>"$myCode",'month'=>"$myMonth",'day'=>"$myDay",'year'=>"$myYear"));

原始表单位于下一页上，但我在通话中使用了表单的操作页面:

The original form is located on the following page, but I'm using the form's action page in the call:

wunderground.com/history/

最终，我想从重定向页面获取内容，例如:

Ultimately I want to get contents from the redirected page, which is for example:

http://www.wunderground.com/history/airport/CWTA/2013/1/24/DailyHistory.html?req_city=McTavish&req_state=QC&req_statename=Quebec&MR=1

但是，如上所述，表单采用了不同的元素，即代码，月，日，年.

However as above, the form takes different elements, i.e. code, month, day, year.

推荐答案

为什么不 ?

function http_post ($url, $data)
{
    $data_url = http_build_query ($data);
    $data_len = strlen ($data_url);
    date_default_timezone_set('America/New_York');
    $curl = curl_init($url);
    curl_setopt_array(array(
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_FOLLOWLOCATION => true,
    ));

    $content = curl_exec();

    curl_close($curl);

    return array (
        'content' => $content,
        'headers' => $http_response_header,
    );

 }

此外，您的函数名为post，但您正在执行GET请求

Also, your function is named post but you are doing GET request
