刮ASPX Web表单用wget？ [英] Scrape ASPX web form with wget?

问题描述

有关数据采集/分析的项目，我想在的http://www.lasuperiorcourt.org/civilcasesummarynet/ui/?CT=AP&casetype=appellate,但我有一点成功为止。

For a data collection/analysis project, I am trying to download entries in a aspx web form at http://www.lasuperiorcourt.org/civilcasesummarynet/ui/?CT=AP&casetype=appellate, but I'm having little success so far.

我们的想法是，通过wget和输出的结果，下载从网页的相关信息，以一个单一的HTML文件。从输出结果我就再编上相关案件所提取的数据统计（例如从案例号BV024000到BV028933）。

The idea is to download the relevant information from the web page through wget and output the results to a single html file. From the resulting output I would then compile stats on the extracted data on relevant cases (e.g. from case nos BV024000 to BV028933).

不过，我遇到了麻烦wget来从表单中检索数据。我一直在使用：

However, I'm having trouble getting wget to retrieve data from the form. I've been using:

wget --post-data "frmsearch=BV024000" http://www.lasuperiorcourt.org/civilcasesummarynet/ui/?CT=AP^&casetype=appellate -O output.html

但我只是得到原始页面返回，而不是形式输出。我在做什么错了？

But I just get the original page back, not the form output. What am I doing wrong?

推荐答案

有两个问题

1. 您必须在您的命令错别字 - 你应该换引号之间的HTTP地址和它的UI / CT的Index.aspx AP =？没有^


2. 当你邮寄的形式，你必须张贴否则你的POST请求未通过验证表单的所有输入字段。

在这里，我做了要求如下

Here I did the request as follow

    wget --post-data "__VIEWSTATE=%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%3D%3D&CaseNumber=BV024000&submit1=Search&casetype=appellate" "http://www.lasuperiorcourt.org/civilcasesummarynet/ui/index.aspx?CT=AP&casetype=appellate" -O output.html

和它的工作看图片 http://i47.tinypic.com/35db8k3.png

也许你将需要设置__VIEWSTATE的新的价值为每一个请求。

Probably you will need to set up a new value of __VIEWSTATE for every request.
