if a request (typically POST) has Content-type header set to application/x-www-form-urlencoded the body is expected to be in the form of a standard querystring with url-encoded key=value pairs joined by &. Form data section then shows the key-value parameters (when viewed parsed). This way was much more common in past because it is a default for HTML forms.

other cases are shown in Request payload section (and nowadays parsed for readability as well for common formats like JSON).

如果请求的Content-Type设置为application/x-www-form-urlencoded，那么这个Post请求被认为是HTTP POST表单请求，参数出现在

其他情况如使用原生AJAX的POST请求如果不指定请求头Request Header，默认使用的Content-Type是text/plain;charset=UTF-8，参数出现在Request payload块。
