编辑“火车采集器/附件上传”

{{火车采集器导航}}
上传文件到[[网站]]是一个比较复杂的过程，需要有一定编程基础才好理解。这里只提供编写方法。　　

[[火车采集器]]自2009版起支持[[附件]]上传到网站,这个功能可以将采集来的图片或文件以附件的形式发布到[[论坛]]或[[cms]]里边去.此功能标准版或更高版本支持.

使用这个功能很方便,主要是模块做好就可以使用了.这里讲一下如何制作附件发布模块.以[[Discuz|dz]]7.0为例(注意,需具备编写模块的能力):

先发一个附件帖,看下抓取的数据包.具体的来源页,[[post]]页等和一般的模块制作并无两样,只讲post内容的制作.

来讲一下制作步骤,首先,将 -----------------------------7d91a5211046a 替换为 -----------------------------7dlocoyspider,然后,寻找文件上传部分的代码,确认其样式.可以分析出如下格式:
<pre>
-----------------------------7dlocoyspider
Content-Disposition: form-data; name="attachdesc[]"

fileaa
-----------------------------7dlocoyspider
Content-Disposition: form-data; name="localid[]"

1
-----------------------------7dlocoyspider
Content-Disposition: form-data; name="attachperm[]"

100
-----------------------------7dlocoyspider
Content-Disposition: form-data; name="attachprice[]"

200
-----------------------------7dlocoyspider
Content-Disposition: form-data; name="attach[]"; filename="E:\Documents and Settings\Administrator\桌面\a.txt"
Content-Type: text/plain
</pre>
这是内容a

'''注意，'''这个信息里是可以设置附件等的权限的，但程序目前只提供了循环id,文件地址.所以这里只能写固定值,比如一般的就是默认的0,整理成程序可识别的样式.
<pre>
{本地文件循环:内容}-----------------------------7dlocoyspider
Content-Disposition: form-data; name="attachdesc[]"

-----------------------------7dlocoyspider
Content-Disposition: form-data; name="localid[]"

[循环文件ID]
-----------------------------7dlocoyspider
Content-Disposition: form-data; name="attachperm[]"

0
-----------------------------7dlocoyspider
Content-Disposition: form-data; name="attachprice[]"

0
-----------------------------7dlocoyspider
Content-Disposition: form-data; name="attach[]"; filename="[本地文件路径]"
Content-Type: image/gif

{/本地文件循环}
</pre>

这样上传部分就做好了,其它的抓取的数据包替换一下即可.对于那些可要可不要的参数,可以不使用,去掉,最后,可以组合出这样的post参数
<pre>

{本地文件循环:内容}-----------------------------7dlocoyspider
Content-Disposition: form-data; name="attachdesc[]"

-----------------------------7dlocoyspider
Content-Disposition: form-data; name="localid[]"

[循环文件ID]
-----------------------------7dlocoyspider
Content-Disposition: form-data; name="attachperm[]"

0
-----------------------------7dlocoyspider
Content-Disposition: form-data; name="attachprice[]"

0
-----------------------------7dlocoyspider
Content-Disposition: form-data; name="attach[]"; filename="[本地文件路径]"
Content-Type: image/gif

{/本地文件循环}-----------------------------7dlocoyspider
Content-Disposition: form-data; name="formhash"

[登录随机值2]
-----------------------------7dlocoyspider
Content-Disposition: form-data; name="subject"

[标签:标题]
-----------------------------7dlocoyspider
Content-Disposition: form-data; name="message"

[标签:内容]
-----------------------------7dlocoyspider--
</pre>
 
测试一下,成功上传即可。
