获取数据时,应该如何解决这个问题?
1 如果多次重定向是必须的,则设置curl跟随(CURLOPT_FOLLOWLOCATION)
2 如果多次重定向不可接收,设置最大redirect次数
3 如果你需要自己分析,则自己解析http response ,在做决定
你是想限制重定向次数还是?CURLOPT_MAXREDIRS
参数可以限制//指定最多的HTTP重定向的数量,这个选项是和CURLOPT_FOLLOWLOCATION一起使用的。。
文档地址:http://php.net/manual/zh/function.curl-setopt.php
<code>curl_setopt($ch, CURLOPT_MAXREDIRS, 5);//最多重定向5次</code>
CURL可以自动跟随301的,参见https://github.com/leaps/httpclient/blob/master/src/Leaps/HttpClient/Adapter/Curl.php
