arrays - 在 swift 中调用解析函数失败

Question

我正在开发一个食品配送应用程序，它使用 parse 作为后端。我在通过

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": [{

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

                     "orderType": "takeout",

                              "cart_storeCuisine": "Ethiopian",
                          "cart_storeDescription": "We always serve a quality food. We always serve a quality food. We always serve a quality food. We always serve a quality food.",

                                        "address": "12255 Greenville Ave,Dallas, TX 75243",
                                       "slugname": "TX_DAL_ibex_ethiopian_cuisine_and_bar",
                              "multiple_location": false,
                          "cart_storeDeliveryFee": 15,
                               "cart_storeServes": "Lunch,Dinner",
                                           "busy": false,
                              "cart_storeSeoSlug": "ibex-ethiopian-cusine-and-bar"
                                  },
                       "enable": true,
          "voice_read_mi_label": "fbgcb",
         "voice_read_mi_option": false,
                 "menuTypeName": "Standard"
                            }],
   "lastOrderType": "takeout",
   "searchedAddress": "takeout",
   "timeData": {
                "day": "06-05-2019",
               "time": "12:55 am",
                 "tz": "America/Los_Angeles"
               }
            },
 "unavailable_option": "restaurant_recommendation"
  }

下面是我用来传递它的 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

完成所有这些后，我调用解析函数，如下所示。

PFCloud.callFunction(inBackground: PlaceOrder, withParameters: params) { (data, err) in
        if err != nil {
            print(err!)
        } else {
            print(data!)
        }
    }

但是几秒钟后这给了我错误

"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.}"

我已经在网上搜索了该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，也有缺失字段。此外，menuItems 和 submenuItem 是 JSON 中的数组和代码中的对象。它可能会导致云代码功能失败，因此您无法收到有效的 JSON。尝试以下操作并检查它是否有效。如果它有效，只需用您的变量替换这些值即可。

let params = [
    "source": "card_1EVYuOEynlyM6L4SHgBMJYRQ",
