failed to open stream: HTTP request failed! HTTP/1.1 505 HTTP Version Not Supported

用file_get_contents();就报错 ：failed to open stream: HTTP request failed! HTTP/1.1 505 HTTP Version Not Supported！！！

curl直接返回空

参考： https://blog.csdn.net/bianb123/article/details/81557300

用preg_replace('# #','%20',$url)；处理url

无论 file_get_contents(); 还是curl 都可成功请求
