fastdfs nginx 文件跨域访问

搭好fastdfs以后，正常访问浏览器没问题，但是前端获取的时候会出现跨越访问。因为访问fastdfs的图片的时候是用Nginx访问的，nginx当中要配置跨域访问，前端才能正常获取图片。

一定要在location里面配置如下2行
add_header ‘Access-Control-Allow-Origin’ ‘*’;
add_header ‘Access-Control-Allow-Credentials’ ‘true’;

worker_processes  1;
pid        logs/nginx.pid;
events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  localhost;
        location / {
            root   html;
            index  index.html index.htm;
        }

		#location /group1/M00 {
			#alias /fastdfs_log/fastdfs/file/data;
		#}
		location ~/group([0-9])/M00 {
    		ngx_fastdfs_module;
    		#加上如下2行解决前端获取文件跨域访问的问题
    		add_header 'Access-Control-Allow-Origin' '*';
			add_header 'Access-Control-Allow-Credentials' 'true';

		}
     }
}
