IHP-无法从请求正文中检索特殊字符
我正在尝试使用AJAX发送请求：
const formBody = document.getElementById('body'); // my form data
const XHR = new XMLHttpRequest();
const params = "body=" + formBody;
XHR.open("POST", window.origin + '/CreateFormAction');
XHR.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
XHR.send(params);
相应的IHP操作：
action CreatePostAction = do
rBody <- getRequestBody
putStrLn $ tshow rBody -- this returns: ""
renderPlain "Request Received"
当我尝试发送诸如'$'，'+'等的特殊字符时，这是我在服务器上收到的请求：
POST /CreatePostMessage
Params: [("body"," ")]
Request Body: body=+
Accept: */*
Status: 200 OK 0.025023s
I'm trying to send the request using ajax:
const formBody = document.getElementById('body'); // my form data
const XHR = new XMLHttpRequest();
const params = "body=" + formBody;
XHR.open("POST", window.origin + '/CreateFormAction');
XHR.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
XHR.send(params);
The corresponding IHP action:
action CreatePostAction = do
rBody <- getRequestBody
putStrLn $ tshow rBody -- this returns: ""
renderPlain "Request Received"
When I try sending special characters like '$', '+', etc., this is the request I get on server:
POST /CreatePostMessage
Params: [("body"," ")]
Request Body: body=+
Accept: */*
Status: 200 OK 0.025023s

您必须使用
encodeuricomponent（）对FormBody进行编码，以编码特殊字符，如下所示：您的IHP操作应该能够处理特殊字符。
You have to encode the formBody using
encodeURIComponent()to encode special characters as follows:Your IHP action should be able to handle special characters then.
