service seacat start
service seacat stop
service seacat status
usage: seacatctl command where command is: 1) list list current settings 2) set [port|rcj|vxsmin|vxsmax|pictureHome|captureWaitTime|waterMark] value set config 3) proxy [ on <IP> <PORT> | off ] set or clear proxy setting 4) help print this help info
Example 1: seacatctl list List current settings. Example 2: seacatctl set port 4444 Set Seacat listen on 4444 port. Example 3: seacatctl set rcj 4444-5555-6666 Set register code to 4444-5555-6666. Example 4: seacatctl set vxsmin 5 Start 5 virtual browser when Seacat starts. Example 5: seacatctl set pictureHome /root Default picture storage home is /root. Example 6: seacatctl set captureWaitTime 1500 Set wait time before capture to 1500ms. Example 7: seacatctl set waterMark zhuatang.com Set watermark text to zhuatang.com. Example 8: seacatctl proxy on 192.168.28.91 8080 Set proxy : 192.168.28.91, port 8080. Example 9: seacatctl proxy off Clear proxy. Note：vxsmax not used.
usage: capture [-h host] [-p port] [-f] [-s WWWxHHH...] [-w timeToWait] [-o imageFormat] url1 url2 ...
Options: -h host which Seacat listens on, default: localhost -p port which Seacat listens, default: 5060 -f enable full page snapshot -s specify various thumnail sizes, such as "400x300 800x600" -w wait time before capture (unit: milliseconds) -o image output format, default: png. url1 url2... URLs you want to take snapshot on.
Output:
<url> {+++|---} <scid>
+++ capture OK
--- capture failed
Example1: capture www.zhuatang.com www.wenwenba.com Example2: capture -s "109x82 330x220" www.zhuatang.com www.wenwenba.com Example3: capture -f -s "82x78 400x300" www.zhuatang.com www.zaobao.com
Default listen on port: 5060
Request - client send snapshot request as follows (Each line ends with <LF>, <LF> stands for new line character, request ends with blank line)
GET <url> <LF>
thumb-sizes: <size1> <size2> ... <LF>
enable-full: 0|1 <LF>
picture-home: <pictureHome> <LF>
prefix: <prefix> <LF>
suffix: <suffix> <LF>
rename-to: <renameTo> <LF>
content-length: <length> <LF>
<LF>
<contents>
Note:<url> is url you'll take snapshot on, it's a must; <sizeN> is thumbnail size, it's format: WWWxHHH, WWW is snapshot width, HHH is snapshot height. Take full page snapshot when enable-full is 1; <pictureHome> is directory of image storage; <prefix> specify prefix of snapshot file; <suffix> specify suffix of snapshot file; <renameTo> can rename snapshot file; When you want send/post some data or arguments to specified url, you must specify <length> and <contents>.
Response message (Snapshot OK)
SEACAT/3.8 200 OK <LF>
SCID: <SCID> <LF>
<LF>
Note: <SCID> is prefix of snapshot file (including path), snapshot filename format is <SCID>-WWWxHHH.<suffix>, full page snapshot filename format is <SCID>-full.<suffix>. <suffix> is image format, default png. If request has rename-to option, snapshot filename will be <SCID>.<suffix>.
Response message(Snapshot failed)
