如何在不是直接链接而是javascript click.submit()的网页上下载文件？

Question

例子是http://developer.amd.com/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/downloads/

这些文件列在一个需要javascript才能在click.submit()上运行的表中。wget在这种情况下不起作用。

您必须使用wget --post-data来构造一个字符串，其中包含要在表单中发送的所有值，还有--content-disposition和--trust-server-names，以允许使用服务器提供的名称。您还需要使用页面url本身，因为表单操作是""。

从页中的第一份表格：

<form method="post" action="" id="download-1">
  <input type="hidden" value="12a6c92ab9" name="amd_developer_central_nonce" id="amd_developer_central_nonce">
  <input type="hidden" value="/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/downloads/" name="_wp_http_referer">
  <input type="hidden" value="QU1ELUFQUC1TREstdjIuOS1sbngzMi50Z3o=" name="f">
</form>

您将构造以下命令：wget --content-disposition --trust-server-names --post-data='amd_developer_central_nonce=12a6c92ab9&_wp_http_referer=/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/downloads/&f=QU1ELUFQUC1TREstdjIuOS1sbngzMi50Z3o=' http://developer.amd.com/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/downloads/，在操作中：

aularon ~ $  wget --content-disposition --trust-server-names --post-data='amd_developer_central_nonce=12a6c92ab9&_wp_http_referer=/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/downloads/&f=QU1ELUFQUC1TREstdjIuOS1sbngzMi50Z3o=' http://developer.amd.com/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/downloads/
