微信支付：appid 未关联 paysignkey

Question

微信支付操作中的签名等都是在后台做的，安卓端是可以正常支付，但是 iOS 端一直在微信提示：“appid 未关联paysignkey”

返回的 Response errCode=-2 errStr=nil type=0

WXApi.registerApp("wxxxxxxxxxxxx1")

let request = PayReq()
request.partnerId = "14xxxxxxx2";
request.prepayId = String(describing: dict["prepay_id"]);
request.package = "Sign=WXPay";
request.nonceStr = dict["nonce_str"] as! String;
let time:Int = Int(dict["timestamp"] as! String)!
let time32 = UInt32(truncatingBitPattern: time)
request.timeStamp = time32
request.sign = dict["sign"] as! String;
return request

Answer 1

是这行代码错误：

request.prepayId = String(describing: dict["prepay_id"]);

转字符串不能这么转。。

Answer 2
