html - CURL：当 HTML 页面有脚本时撰写方法 POST

Question

我正在尝试编写一个 bash 脚本来自动发送对数百个此类垃圾邮件链接的投诉： https://script.google.com/macros/s/hash 仅用作重定向到众所周知的犯罪域。

投诉此类垃圾链接的正确地址是： https: //support.google.com/code/contact/cloud_platform_report

通常对于这样的情况，我使用 curl 的方案：

1. 下载主页
2. 解析 home.html 以查找表单参数和方法 POST
3. 发送带有所需参数的 curl 答案

像这样的脚本：

#!/bin/bash

# input parameters
name=""   # put here the user name
email=""      # put the google email
option="Google App Engine"
date="07/24/2021"
details="https://script.google.com/macros/s/<hash>"

# configuration variables
reportURL="https://support.google.com/code/contact/cloud_platform_report"
pars="-s -S -L -b cs.txt -c cs.txt" # curl default parameters
if (test -e "cs.txt" ) then { rm cs.txt ; } fi

# 1) download homepage ...
file=home.html
url=$reportURL
curl -o $file $pars $url

# 2) parse homepage to extract parameters ...
var1=`cat $file | grep <something1>`
var2=`cat $file | grep <something2>`
data="name=$name&email=$email&option=$option&&date=$date&detail=$detail&FORM=$var1&SUBMIT=$var2"

# 3) send the answer with parameters ...
file=reply.html
url=$reportURL # may differ
curl -o $file $pars --data "$data" $url

但是通过第 1 步下载的这个主页，我可以找到表单参数、许多脚本但没有 POST 方法（而我可以在脚本代码中找到“POST”）。

如何构建卷曲答案？
