About application/x-www-form-urlencoded
As a data format of form, application/x-www-form-urlencoded has its own characteristics
<form action= "handle.php" method= "post" >
<input type= "text" name= " uname" class= " uname" /><br />
<input type= "text" name= "email" class= " email " /><br />
<textarea rows= "5" cols= "5" name= "txt" ></textarea><br />
<input type= "submit" name= "submit" value= " submit " />
</form>
If the enctype value is not specified, the default value is application/x-www-form-urlencoded. Of course, this data format cannot support file uploads. If we need to upload files at the same time, we can manually specify enctype="multipart/form-data".
Figure 2
From Figure 2, we can verify its replacement rule
When using the GET method for request, the form data is encoded as application/x-www-form-urlencoded and appended to the request address, separated by '?'.
Let's briefly talk about the third value of enctype, text/plain. This encoding method is similar to application/x-www-form-urlencoded, but text/plain only replaces line breaks and spaces, and does not encode special characters. The Chinese characters in the above example will not be encoded.
Furthermore, if the request is made in POST mode, the name and value in the message body will not be reorganized into the form of name=value&name=value.
The above is a brief introduction to the application/x-www-form-urlencoded encoding of the form. You are welcome to leave a message below for discussion and common progress.
