爲什麼我的cURL在PHP中獲得403 Forbidden，而cURL在shell中獲得200？

代碼：爲什麼我的cURL在PHP中獲得403 Forbidden，而cURL在shell中獲得200？

$ch = curl_init(); 
curl_setopt ($ch, CURLOPT_URL, "https://detail.1688.com/offer/543783250479.html?sk=consign"); 
curl_setopt($ch, CURLOPT_HEADER, true); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
$a = curl_exec($ch); 
$data = curl_exec($ch); 
curl_close($ch); 
var_dump($data);

結果：

string(339) "HTTP/1.1 403 Forbidden 
Server: nginx/1.11.1 
Date: Tue, 16 May 2017 03:46:32 GMT 
Content-Type: text/html; charset=utf-8 
Content-Length: 169 
Connection: keep-alive 

<html> 
<head><title>403 Forbidden</title></head> 
<body bgcolor="white"> 
<center><h1>403 Forbidden</h1></center> 
<hr><center>nginx/1.11.1</center> 
</body> 
</html> 
"

雖然我在shell中運行curl -I https://detail.1688.com/offer/543783250479.html?sk=consign，它會返回200：

任何人都可以請給我，爲什麼我得到一些提示403通過cURL在PHP中？

我試過你的代碼，它正常工作，嘗試從不同的IP地址，你可能已被禁止。 –

返回的頭沒有的useragent：

HTTP/1.1 302 Moved Temporarily 
Date: Tue, 16 May 2017 04:15:46 GMT 
Content-Type: text/html 
Content-Length: 266 
Connection: keep-alive 
Location: http://127.0.0.1/?sk=consign

最重要的部分是：

Location: http://127.0.0.1/?sk=consign

如果我使用useragent，我得到：

HTTP/1.1 200 OK

哪個是正確的，它返回使用所需html

代碼：

$url = "http://detail.1688.com/offer/543783250479.html?sk=consign"; 
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:53.0) Gecko/20100101 Firefox/53.0"); 
$html = curl_exec($ch); 
curl_close($ch); 
print $html;

在捲曲-I代表頭部的請求。嘗試在你的PHP頭請求作爲：

curl_setopt($ch, CURLOPT_NOBODY, true);

並採用試試看
