Curl/wget to test the response header information for an HTTP request

1. Wget–debug

Wget can use the debug information to view the information header, as follows:

[Email protected] ~]#wget--debug http://192.168.1.101:8080/ufe/service/testDEBUG output created by Wget1.12On linux-GNU.-- --Geneva- to  +: on:Geneva--http://192.168.1.101:8080/ufe/service/testIs connecting192.168.1.101:8080... is connected.

2. Wget-save-headers

To use the-S, –save-headers option, however only the response header information can be viewed at this time, note that both debug and save-headers are output to the file.

3. wget--spider

To determine whether a file or page exists, you can use the command:

wget --spider-nv http://ip/bugfree/index.php-Geneva  ::url:http: //ip/bugfree/index.php/site/login OK

4. Curl-v

You can view the file header information for the URL as follows:

[[email protected] ~]# curl-v http://192.168.1.101:8080/ufe/service/test* About to connect () to192.168.1.101Port8080(#0)* Trying192.168.1.101. .. connected* Connected to192.168.1.101(192.168.1.101) port8080(#0)> Get/ufe/service/test http/1.1> user-agent:curl/7.19.7(X86_64-REDHAT-LINUX-GNU) libcurl/7.19.7nss/3.14.0.0zlib/1.2.8libidn/1.18libssh2/1.4.2> Host:192.168.1.101:8080> Accept: */*>< http/1.1  $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: -< Date:tue, toMar -  One: -: OneGMT<* Connection #0to host192.168.1.101Left intact* Closing Connection #0

5. Curl-i

Use the-I (uppercase I)--head option of Curl to view only the response header information:

[[email protected] ~]# curl-i http://192.168.1.101:8080/ufe/service/testhttp/1.1 405Method not Allowedserver:apache-coyote/1.1Access-control-allow-origin: *Access-control-allow-Methods:post, GET, OPTIONS, deleteaccess-control-max-age:3600Access-control-allow-headers:x-requested-withallow:getcontent-type:text/html;charset=utf-8Content-language:encontent-length:1047Date:tue, toMar -  One: to: theGmt

6. Get the status code of the URL

[[email protected] ~]# Curl-o/dev/null -S-w %{http_code} http://192.168.1.101:8080/ Ufe/service/test
