1. wget –debug
wget可以使用debug信息来查看信息头，如下：
[root@localhost ~]# wget --debug http://192.168.1.101:8080/UFE/service/test DEBUG output created by Wget 1.12 on linux-gnu. --2015-03-31 19:01:03-- http://192.168.1.101:8080/UFE/service/test 正在连接 192.168.1.101:8080... 已连接。 Created socket 3. Releasing 0x000000000087cca0 (new refcount 0). Deleting unused 0x000000000087cca0. ---request begin--- GET /UFE/service/test HTTP/1.0 User-Agent: Wget/1.12 (linux-gnu) Accept: */ * Host: 192.168.1.101:8080 Connection: Keep-Alive ---request end--- 已发出 HTTP 请求，正在等待回应... ---response begin--- HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Access-Control-Allow-Origin: * Access-Control-Allow-Methods: POST, GET, OPTIONS, DELETE Access-Control-Max-Age: 3600 Access-Control-Allow-Headers: x-requested-with Content-Type: text/plain;charset=ISO-8859-1 Content-Length: 14 Date: Tue, 31 Mar 2015 11:13:47 GMT Connection: keep-alive ---response end--- 200 OK Registered socket 3 for persistent reuse. 长度：14 [text/plain] 正在保存至: “test.1” 100%[======================================>] 14 --.-K/s in 0s 2015-03-31 19:01:03 (2.03 MB/s) - 已保存 “test.1” [14/14])
2. wget -save-headers
以使用-S、–save-headers选项，不过此时只能查看响应头部信息，注意，debug和save-headers都会输出到文件。
3. wget --spider
判断一个文件或者页面是否存在，可以使用一下命令：
[root@localhost ~]# wget --spider -nv http://ip/bugfree/index.php 2015-03-31 19:12:42 URL: http://ip/bugfree/index.php/site/login 200 OK
4. curl -v
可以查看url的文件头信息，如下：
[root@localhost ~]# curl -v http://192.168.1.101:8080/UFE/service/test * About to connect() to 192.168.1.101 port 8080 (#0) * Trying 192.168.1.101... connected * Connected to 192.168.1.101 (192.168.1.101) port 8080 (#0) > GET /UFE/service/test HTTP/1.1 > User-Agent: curl/7.19.7 (x86_64-redhat-linux-gnu) libcurl/7.19.7 NSS/3.14.0.0 zlib/1.2.8 libidn/1.18 libssh2/1.4.2 > Host: 192.168.1.101:8080 > Accept: */ * > < HTTP/1.1 200 OK < Server: Apache-Coyote/1.1 < Access-Control-Allow-Origin: * < Access-Control-Allow-Methods: POST, GET, OPTIONS, DELETE < Access-Control-Max-Age: 3600 < Access-Control-Allow-Headers: x-requested-with < Content-Type: text/plain;charset=ISO-8859-1 < Content-Length: 14 < Date: Tue, 31 Mar 2015 11:28:11 GMT < * Connection #0 to host 192.168.1.101 left intact * Closing connection #0
5. curl -I
利用curl的-I（大写i）--head 选项仅查看响应头部信息：
[root@localhost ~]# curl -I http://192.168.1.101:8080/UFE/service/test HTTP/1.1 405 Method Not Allowed Server: Apache-Coyote/1.1 Access-Control-Allow-Origin: * Access-Control-Allow-Methods: POST, GET, OPTIONS, DELETE Access-Control-Max-Age: 3600 Access-Control-Allow-Headers: x-requested-with Allow: GET Content-Type: text/html;charset=utf-8 Content-Language: en Content-Length: 1047 Date: Tue, 31 Mar 2015 11:31:42 GMT
6. 获取url的状态码
[root@localhost ~]# curl -o /dev/null -s -w %{http_code} http://192.168.1.101:8080/UFE/service/test 200
