Variables in wget post data
提问by user1111098
I am working on a simple bash script to download images from the website Tumblr. The idea is to use readto get login info from the user, and wget --post-datato log in, and this is what I have:
我正在编写一个简单的 bash 脚本来从 Tumblr 网站下载图像。这个想法是用来read从用户那里获取登录信息并wget --post-data登录，这就是我所拥有的：
read -p "Tumblr login email: " EMAIL
read -p "Tumblr login password: " PASSWRD
wget --user-agent=Mozilla/5.0 --save-cookies cookies.txt --post-data 'email=$EMAIL&password=$PASSWRD' --no-check-certificate https://www.tumblr.com/login
However, it is sending "$EMAIL"and "$PASSWRD"instead of the strings for the variables, is there any way to get it to send values that have been inputted by the user?
但是，它正在发送"$EMAIL"而"$PASSWRD"不是变量的字符串，有没有办法让它发送用户输入的值？
