我一直在嘗試使用AIDA disambiguation service。他們發佈的cURL示例在終端上運行良好。但是,當我嘗試通過PHP實現它時,我立即得到一個空的響應。最重要的是,我試圖基本上從Javascript訪問這個資源,但據我所知,通過PHP是從另一個域訪問資源的最佳途徑。cURL通過終端工作,不通過PHP
我的PHP代碼:
<?php
//set POST variables
$url = $_POST['url'];
unset($_POST['url']);
$curl = curl_init();
curl_setopt($curl,CURLOPT_URL,$url);
curl_setopt($curl,CURLOPT_POST,count($_POST));
curl_setopt($curl,CURLOPT_HTTPHEADER,array('Expect:'));
curl_setopt($curl,CURLOPT_POSTFIELDS,$_POST);
curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);
$a = curl_exec($curl);
error_log('Status: '.var_dump(curl_getinfo($curl)));
curl_close($curl);
?>
的curl_getinfo:
array(26) {
["url"]=>
string(56) "https://gate.d5.mpi-inf.mpg.de/aida/service/disambiguate"
["content_type"]=>
NULL
["http_code"]=>
int(0)
["header_size"]=>
int(0)
["request_size"]=>
int(0)
["filetime"]=>
int(-1)
["ssl_verify_result"]=>
int(0)
["redirect_count"]=>
int(0)
["total_time"]=>
float(0.125)
["namelookup_time"]=>
float(0)
["connect_time"]=>
float(0.063)
["pretransfer_time"]=>
float(0)
["size_upload"]=>
float(0)
["size_download"]=>
float(0)
["speed_download"]=>
float(0)
["speed_upload"]=>
float(0)
["download_content_length"]=>
float(-1)
["upload_content_length"]=>
float(-1)
["starttransfer_time"]=>
float(0)
["redirect_time"]=>
float(0)
["redirect_url"]=>
string(0) ""
["primary_ip"]=>
string(12) "139.19.87.30"
["certinfo"]=>
array(0) {
}
$a
就是空的。 $url
設置正確。唯一的其他變量,text
,似乎也正確設置。任何人都知道這裏可能會出錯嗎?
