ajax 參數出現在Request payload導致request.getParameter(name)是擷取不到值

標籤：plain   ack   form   common   parse   orm   pair   set   ram   

 

參考：http://stackoverflow.com/questions/10494574/what-is-the-difference-between-form-data-and-request-payload

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).

如果請求的Content-Type設定為application/x-www-form-urlencoded，那麼這個Post請求被認為是HTTP POST表單請求，參數出現在

其他情況如使用原生AJAX的POST請求如果不指定要求標頭Request Header，預設使用的Content-Type是text/plain;charset=UTF-8，參數出現在Request payload塊。
