Php get url重定向时,文件\u get\u contents()不工作
我使用的功能是:Php get url重定向时,文件\u get\u contents()不工作,php,file-get-contents,Php,File Get Contents,我使用的功能是: 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 ($url, false , stream_context_create (
function http_post ($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'=>"$myYear"));
原始表单位于下一页,但我正在调用中使用表单的操作页面:
wunderground.com/history/
最终,我希望从重定向页面获取内容,例如:
http://www.wunderground.com/history/airport/CWTA/2013/1/24/DailyHistory.html?req_city=McTavish&req_state=QC&req_statename=Quebec&MR=1
但是,如上所述,表单采用不同的元素,即代码、月、日、年 试试下面的功能
function http_post ($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, true
, 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'=>$http_response_header
);
}
为什么不呢
此外,您的函数名为
post
,但您正在执行GET
requestTry curl:如果我没有弄错,这应该可以工作,因为默认值是遵循重定向。除非已到达max_重定向,或者正在超时。嗯?据我所知,您所做的只是将第二个参数的布尔值更改为true
,如果您阅读了只需切换包含路径中的搜索与否。谢谢@crypticツ . 是,仅更改布尔值部分。我已经执行了代码,它工作得很好。天气api正在返回完美的结果。我正在做一些调整,但它看起来会工作,谢谢!
function http_post ($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,
);
}
