Question

我正在尝试在其中一个应用中添加帖子。

我尝试过RestClient，它工作正常。

{
"TypeId": 1, 
"UserId": 9, 
"Email": "",
"appLang": "en", 
"IsGallery": false, 
"Videos": [
{"IsFront": true, "Video": "frontVideo.mp4"},
{"IsFront": false, "Video": "backVideo.mp4"}
], 
"key": "abc-def", 
"Title": "Post 1", 
"Longitude": "", 
"userId": "9", 
"Id": 0, 
"Latitude": "", 
"Website": "", 
"ContactNo": "", 
"Photos": [
{"IsFront": true, "Photo": "frontImage.png"},
{"IsFront": false, "Photo": "backImage.png"}
], 
"Hashtag": ""
}

这将在返回帖子时返回我的输出。

[
  {
    "Id": 25,
    "UserId": 9,
    "Name": " ",
    "UserName": "ff006",
    "Phone": "+974 1234566",
    "DisplayName": "dff006",
    "UserPhoto": "http://myweb.com//Files/UserPhotos/t2z8mryE1KpM9o.jpg",
    "Title": "Post 1",
    "Hashtag": "",
    "Longitude": "",
    "Latitude": "",
    "Website": "",
    "Email": "",
    "ContactNo": "",
    "FromDateString": "",
    "FromDate": null,
    "ToDateString": "",
    "ToDate": null,
    "ViewersCount": 0,
    "FavoritesCount": 0,
    "IsFollowing": false,
    "IsFollowingPending": false,
    "IsFavorite": false,
    "IsReport": false,
    "AdminAdded": false,
    "Photo": "http://myweb.com//Files/PostPhotos/frontImage.png",
    "AddedOnDate": "18/09/2018 04:07 PM",
    "AddedOnFormatted": "04:07 PM",
    "AddedOn": "2018-09-18T16:07:39.923",
    "PostPhotos": [
      {
        "PostPhotoId": 10,
        "Photo": "http://myweb.com//Files/PostPhotos/frontImage.png",
        "IsFront": true
      },
      {
        "PostPhotoId": 11,
        "Photo": "http://myweb.com//Files/PostPhotos/backImage.png",
        "IsFront": false
      }
    ],
    "PostVideos": [
      {
        "PostVideoId": 9,
        "Video": "http://myweb.com//Files/PostVideos/frontVideo.mp4",
        "IsFront": true
      },
      {
        "PostVideoId": 10,
        "Video": "http://myweb.com//Files/PostVideos/backVideo.mp4",
        "IsFront": false
      }
    ]
  }
]

现在我正在以编程方式尝试添加，但是发布的照片和视频对象中存在问题。

以下是我尝试过的内容。

我已经创建了如下对象，并尝试如上所述调用http://myweb.com/API/Posts/AddPost

var param = Dictionary<String, Any>()

var photos = [[String: Any]]()
photos.append(["IsFront": true, "Photo": frontPhotoName])
photos.append(["IsFront": false, "Photo": backPhotoName])

var videos = [[String: Any]]()
videos.append(["IsFront": true, "Video": frontVideoName])
videos.append(["IsFront": false, "Video": backVideoName])

param["Id"] = 0
param["appLang"] = "myLang".localized()
param["UserId"] = Int(UserDefaults.standard.string(forKey: "userId")!)
param["TypeId"] = 1
param["Title"] = postTitleTV.text!
param["Hashtag"] = ""
param["Latitude"] = (currLat.containsIgnoringCase(find: "0.00") ? "" : currLat)
param["Longitude"] = (currLong.containsIgnoringCase(find: "0.00") ? "" : currLong)
param["Website"] = websiteTF.text!
param["Email"] = emailTF.text!
param["ContactNo"] = phoneTF.text!
param["IsGallery"] = false
param["Photos"] = photos
param["Videos"] = videos
param["key"] = APIKey

这会添加帖子，但是当我尝试获取帖子时，它不会返回如下的空数组。

[
  {
    "Id": 26,
    "UserId": 9,
    "Name": " ",
    "UserName": "ff006",
    "Phone": "+974 1234566",
    "DisplayName": "dff006",
    "UserPhoto": "http://myweb.com//Files/UserPhotos/t2z8mryE1KpM9o.jpg",
    "Title": "Post 1",
    "Hashtag": "",
    "Longitude": "",
    "Latitude": "",
    "Website": "",
    "Email": "",
    "ContactNo": "",
    "FromDateString": "",
    "FromDate": null,
    "ToDateString": "",
    "ToDate": null,
    "ViewersCount": 0,
    "FavoritesCount": 0,
    "IsFollowing": false,
    "IsFollowingPending": false,
    "IsFavorite": false,
    "IsReport": false,
    "AdminAdded": false,
    "Photo": "",
    "AddedOnDate": "18/09/2018 04:13 PM",
    "AddedOnFormatted": "04:13 PM",
    "AddedOn": "2018-09-18T16:13:58.303",
    "PostPhotos": [

    ],
    "PostVideos": [

    ]
  }
]

“照片和视频”对象为空。

"PostPhotos": [

],
"PostVideos": [

]

知道我在做什么错吗？

我正在控制台上打印的数据如下。

["appLang": "en", "UserId": 9, "TypeId": 1, 
    "Email": "", "IsGallery": false, 
    "Videos": [["IsFront": true, "Video": "frontVideo.mp4"], ["IsFront": false, "Video": "backVideo.mp4"]], 
    "key": "abc-def", "Title": "Post 1", "Longitude": "", 
    "userId": "9", "Id": 0, "Latitude": "", "Website": "",  "ContactNo": "",
     "Photos": [["IsFront": true, "Photo": "frontImage.png"], ["IsFront": false, "Photo": "backImage.png"]], 
    "Hashtag": ""]

我还将参数打印为dump(param)并获得以下输出。

知道我在做什么错吗？

请注意，我正在使用alamofire执行Web服务。

Answer 1

我刚刚为Alamofire请求添加了ParameterEncoding的编码（如下所示），

JSONEncoding.default

发布请求不添加对象的内部数组

知道我在做什么错吗？
