我关注了this post看看如何将数据传递给php的file_get_contents函数，但我似乎无法使用以下方式取回数据:
$data = $_POST['my_param']; // Where my_param is the name of the parameter passed
有人知道如何取回我使用 file_get_contents 调用的脚本中发送到 file_get_contents 的参数值吗？
提前致谢
最佳答案
有示例@php.net http://php.net/manual/en/function.file-get-contents.php#102575
代码:
<?php
/**
make an http POST request and return the response content and headers
@param string $url url of the requested script
@param array $data hash array of request variables
@return returns a hash array with response content and headers in the following form:
array ('content'=>'<html></html>'
, 'headers'=>array ('HTTP/1.1 200 OK', 'Connection: close', ...)
)
*/
function http_post ($url, $data)
{
$data_url = http_build_query ($data);
$data_len = strlen ($data_url);
return array ('content'=>file_get_contents ($url, false, stream_context_create (array ('http'=>array ('method'=>'POST'
, 'header'=>"Connection: close\r\nContent-Length: $data_len\r\n"
, 'content'=>$data_url
))))
, 'headers'=>$http_response_header
);
}
?>
但在实际应用中我不会使用这种方法。我建议您改用curl。
curl 的简单示例:
<?php
$ch = curl_init(); // create curl handle
$url = "http://www.google.com";
/**
* For https, there are more options that you must define, these you can get from php.net
*/
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_POST, true);
curl_setopt($ch,CURLOPT_POSTFIELDS, http_build_query(['array_of_your_post_data']));
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT ,3); //timeout in seconds
curl_setopt($ch,CURLOPT_TIMEOUT, 20); // same for here. Timeout in seconds.
$response = curl_exec($ch);
curl_close ($ch); //close curl handle
echo $response;
?>
使用curl，你可以100%从$_POST获取post参数。 我已经在数十个项目中使用了curl，以前从未让我失望过。
