  1. downloaded ZooKeeper from Apache mirrors http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.12/

  2. Add the same file as zoo_sample.cfg in folder conf and rename it to zoo.cfg. and change dataDir with your

  3. Please confirm whether the Java runtime environment is installed

  4. run bin/zkServer.cmd in you zookeepr folder

  5. Start up zookeeper

  6. Compile RuiJi.Net.Cmd and run RuiJi.Net.Cmd.exe

if You see the following information

Server Start At http://x.x.x.x:x
proxy x.x.x.x:x ready to startup!

About RuiJi Expression

RuiJi Expression is a way to quickly add the rules of page extraction and implement soft coding. The ruiji expressions are as simple and understandable as possible.Before we start, we should first understand the rule model of RuiJi.Net.

The RuiJi expression uses the structure described in the figure above to extract the pages that need to be extracted, and the extraction unit is Block, as shown in the following figure.

Selectors is a list of selector Tiles is a region that needs to be repeatedly extracted Metas is the metadata that needs to be extracted Blocks is a subBlock that needs to be extracted within Block

Image text

If you need to extract http://www.ruijihg.com/开发, you need to observe the structure of the page first.You can use F12 to look at the structure of the page

Image text

First, make sure that the result of the Block selector is unique.

Image text

The definition of Block can be as follows

#content
css .pt-cv-view:ohtml

Continue adding tile

[tile]
    #tiles
    css .pt-cv-content-item:ohtml

    [meta]
    #title
    css .pt-cv-title:text

    #content
    css .pt-cv-content:html
    ex 阅读更多... -e

You may notice \t, because both block and tile contain meta, so the tile selector part and tile meta are \t as the current tile flag.

The complete Block description structure is as follows

[Block]
#blockname
selector

[blocks]
    @subblockname1
    @subblockname2

[tile]
    #tilename
    tile selector

    [meta]
    #meta1
    selector

    #meta2
    selector

[meta]
    #blockmeta1
    selector

    #blockmeta2
    selector
I'm still improving RuiJi Expression
