Coffeescript中的简单Ajax请求

Question

I have a small server running on localhost:8083

I tested a put request with Chrome postman client

http://localhost:8083/addcompany?{"Ticker":"Hello", "Name":"Hello, Inc."}

which translates in

POST /addcompany?{"Ticker":"Hello", "Name":"Hello, Inc."} HTTP/1.1
Host: localhost:8083
Cache-Control: no-cache

and correctly returns:

{
"Ticker": "Hello",
"Name": "Hello, Inc."
}

I have tried to implement the same request in my client app.

postTicker = (tkr, name) ->
    console.log "posting #{tkr}, #{name}"
    aCompany = JSON.stringify ({Ticker:tkr, Name: name})
    console.log aCompany
    queryUrl =  encodeURI 'http://localhost:8083/addcompany'
    $.ajax queryUrl,
        type: 'POST'
        timeout: 5000
        data: aCompany
        success: (response) ->
            #parsedResponse = $.parseJSON response
            alert response
            #removeAddBtn (parsedResponse.ticker)
        error: (response) ->
            console.log "AJAX Error: #{response}"

The request results in the error message:

Uncaught TypeError: string is not a function 

for data: aCompany .

I believe you don't need to stringify your data. Could you try to change the third line of your javascript:

from :

aCompany = JSON.stringify ({Ticker:tkr, Name: name})

to :

aCompany = {Ticker: tkr, Name: name}
