我正在开发一个食品交付应用程序，该应用程序将parse作为其后端。通过
调用placeOrder API时遇到问题 PFCloud.callFunction(inBackground: PlaceOrder, withParameters: params) { (data, err) in}
请查看我需要在下面发布的JSON。
{
"source": "card_1EVYuOEynlyM6L4SHgBMJYRQ",
"userId": "YjSZYSXEp7",
"data": {
"menuItems": [{
"id": "QSYa2JDcIm",
"title": "Rice With Tibss(Beef)",
"menuTitle": "Rice With Tibss",
"submenuItem": [{

"price": 12,
"desc": "Fillings?"
}],
"price": 24,

"day": "06-05-2019",
"time": "12:55 am",
"tz": "America/Los_Angeles"
}
},
"unavailable_option": "restaurant_recommendation"
}
下面是我用来传递代码的Swift代码。
let storeInfo: Dictionary = [CartStoreId: self.cartStoreId, CartStoreName: self.cartRestaurantName, CartStoreImage: self.cartStoreImage, CartStoreCuisine: self.cartStoreCuisine, CartStoreDescription: self.cartStoreDescription, CartStoreRating: self.cartStoreRating, CartStoreDelivery: self.cartStoreDelivery, Takeout: self.takeOut, Address: self.address, Slugname: self.slugName, MultipleLocation: self.multipleLocation, CartStoreDeliveryFee: self.cartStoreDelivery, CartStoreServes: self.cartStoreServes, Busy: self.busy, CartStoreSeoSlug: self.cartStoreSeoSlug] as Dictionary
let subMenuItem = ["id": "zaOo6G4KSV", "name": "Beef", "price": 12, "desc": "Fillings?", "voice_read_submi_label":"bf", "voice_read_submi_option":false, "disabled": false] as [String: Any]
let ordersDictionary = [
"id" : "1234",
"title" : "Test",
"menuTitle" : "MenuName",
"price" : 23,
"qty" : 2,
"storeId" : 23,
"orderType" : "standard",
"taxState" : 0.22,
"enable" : true,
"menuTypeName" : "Type Name",
"voice_read_mi_label":"fdfs",
"voice_read_mi_option":"false",
"submenuitem": subMenuItem,
"storeInfo": storeInfo
] as Dictionary
let timeData = ["day" : 17-06-2019, "time": "11:00 AM", "tz": "America/Los_Angeles"] as Dictionary
let data = ["menuItems": ordersDictionary, "lastOrderType": "takeout", "searchedAddress": "takeout", "timeData" : timeData] as Dictionary
let params = [UserId: self.userId, "source":"card_1EVYuOEynlyM6L4SHgBMJYRQ", "data": data, "unavailable_option":"restaurant_recommendation","_ApplicationId":"6EuadToYoFGJhI1sX8XnuFBz9tp9l3yH6HxzzXZO", "_JavaScriptKey":"rQkALu9saFtF2oq9yCibyw6mEcs3PVqct3uuP6vg", "_ClientVersion":"js1.6.14", "_InstallationId":"444ec64d-5fcc-7b8e-596e-6be627892c2a",
"_SessionToken":"r:c966376120c8eca77aa63c29d5bebe1a"] as Dictionary
完成所有这些操作后，我将调用如下的parse函数。
PFCloud.callFunction(inBackground: PlaceOrder, withParameters: params) { (data, err) in
if err != nil {
print(err!)
} else {
print(data!)
}
}
但这会在几秒钟后让我出错
"Error Domain=NSCocoaErrorDomain Code=3840 "JSON text did not start with array or object and option to allow fragments not set." UserInfo={NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.}"
我在网上搜索了错误，并进行了相应的修复，但仍然没有成功。请帮助我。

我注意到您的params var与您发送的JSON不兼容，有更多字段，也缺少字段。此外，menuItems和submenuItem在JSON中是一个数组，在代码中是一个对象。这可能会使云代码功能失败，因此您没有收到有效的JSON。请尝试以下操作，并检查其是否有效。在这种情况下，只需将值替换为您的变量即可。
let params = [
