Question

我为什么没有在检查页上填写总数?

“Missing

Apologies.

As my code is working, because it actually got to PayPal and does have all the field correct. I didn t think it was necessary to post the code. I thought it could be answered simply, "you re missing the XXXX variable in your post to PayPal."

但是,考虑到这一点,需要制定法典。

This is COLDFUSION (yes caps because people think this is a dead/dying language).

<cffunction name="expressCheckout" access="remote" returnformat="JSON" output="false" description="Processes PayPal Subscription">
    <cfargument name="L_BILLINGAGREEMENTDESCRIPTION0" type="string" required="yes" />
    <cfargument name="L_BILLINGTYPE0" type="string" required="yes" />
    <cfargument name="AMT" type="numeric" required="yes" />

    <cfset var username = "wpp_1306278086_biz_api1.blahblah.com">
    <cfset var password = "1306278555">
    <cfset var signature = "someSig">
    <cfset var serverURL = "https://api-3t.sandbox.paypal.com/nvp">
    <cfset var version = "65.1">

    <cfset requestData = StructNew()>
    <cfset requestData.USER = "#USERNAME#">
    <cfset requestData.PWD = "#PASSWORD#">
    <cfset requestData.SIGNATURE = "#SIGNATURE#">
    <cfset requestData.SUBJECT = "">
    <cfset requestData.VERSION = "#version#">
    <cfset requestData.METHOD = "SetExpressCheckout">
    <cfset requestData.AMT = "#arguments.AMT#">
    <cfset requestData.DESC = "#arguments.L_BILLINGAGREEMENTDESCRIPTION0#">
    <cfset requestData.CUSTOM = "#session.rfcid#">

    <cfset requestData.returnURL = "http://localhost:8500/rfc2-1/membership/payPalConfirm.cfm">
    <cfset requestData.cancelURL = "http://localhost:8500/rfc2-1/membership/creditcardform.cfm">

    <cfset payPalReturn = doHttppost(requestData, serverURL, "no")>
    <cfset payPalReturn = getNVPResponse(#URLDecode(payPalReturn)#)>

    <cfif payPalReturn.ACK EQ "Failure">
        <!--- return the error message --->
        <cfset payPalReturn.ERRORMESSAGE = #payPalReturn.L_LONGMESSAGE0#>
    </cfif>

    <cfreturn payPalReturn>

</cffunction>

This retuns a json object to the browser. The browser then sends me to: https://sandbox.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=SomeToken

All fine when I get to PayPal. Just missing the total in the left hand box (as diagrammed)

Answer 1

Try appending &useraction=commit to the PayPal redirection URL (https://www.sand Box. Paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=EC-xxxx&useraction=commit)。

这部书签协议并不确定,但值得一枪。它为定期付款工作。

edit:
Actually, on second thought; since it s a billing agreement, which is not for a fixed price (otherwise you wouldn t need a billing agreement in the first place); this would be intended. Since there is no specific price to display.
