NSMutableArray true 转换为 json 输出并在 Swift 3 中使用 Alamofire 将其发布到远程

Question

我有来自CoreData 的NSMutableArray 代码，我想将其转换为Json 数组并将其发布到远程使用Alamofire，我尝试将myArray 转换为jsonArray，但不正确。我的代码在下面。

           let maras = try appDelegate.managedObjectContext.fetch(fetchRequest) as! [Manager]

  if maras.count > 1 {

                let prod: NSMutableDictionary = NSMutableDictionary()
                let prodArray:NSMutableArray = NSMutableArray()

                for i in 0 ..< maras {
                    let a = maras[i]
                    prod.setValue(a.val1, forKey: "val1")
                    prod.setValue(a.val2, forKey: "val2")
                    prod.setValue(a.val3, forKey: "val3")
                    prod.setValue(a.val4, forKey: "val4")
                    prodArray.add(prod)
                }

               print(prodArray)   // OUTOUT UNDER BELOW

在下面输出prodArray错json

(
        {
        val1 = "2324";
        val2 = "1212";
        val3 = 234;
        val4 = "234234";
    },
        {
        val1 = "223324";
        val2 = "12232312";
        val3 = 233242344;
        val4 = "234223423434";
    }
)

必须是有效的JSON，如下所示。 （我的项目中还有SwiftyJson）

[{
    "val1": "2324",
    "val2": "1212",
    "val3": 234,
    "val4": "234234"
}, {
    "val1": "223324",
    "val2": "12232312",
    "val3": 233242344,
    "val4": "234223423434"
}]

之后我想用Alamofire将我的prodArray发布到远程。我的代码在下面

  Alamofire.request(Posturl, method: .post, parameters: prodArray, encoding: URLEncoding.httpBody, headers: headers)
                .responseData{ response in
                   let success = json["status"]["type"].boolValue

                    if success == true {



            }

            }

var json:[String:Any] = [:]


var jsonItem:[String:Any] = [:]

var jsonItemArray:[[String:Any]] = []

    jsonItem = [:]

    jsonItem["val1"] = "2324"
    jsonItem["val2"] = "1212"
    jsonItem["val3"] = 234
    jsonItem["val4"] = "234234"
    jsonItemArray.append(jsonItem)

    jsonItem = [:]
    jsonItem["val1"] = "223324"
    jsonItem["val2"] = "12232312"
    jsonItem["val3"] = 233242344
    jsonItem["val4"] = "234223423434"
    jsonItemArray.append(jsonItem)

print(jsonItemArray)

json["data"] = jsonItemArray

print(json)

[[“val2”：“1212”，“val3”：234，“val4”：“234234”，“val1”：“2324”]，[“val2”：“12232312”，“val3”：233242344 , "val4": "234223423434", "val1": "223324"]]

[“数据”：[[“val2”：“1212”，“val3”：234，“val4”：“234234”，“val1”：“2324”]，[“val2”：“12232312”， “val3”：233242344，“val4”：“234223423434”，“val1”：“223324”]]]

您应该将代码更改为：

var prodArray:[[String:Any]] = []

for i in 0 ..< maras {
    let a = maras[i]

    let prod:[String:Any]
    prod["val1"] = a.val1
    prod["val2"] = a.val2
    prod["val3"] = a.val3
    prod["val4"] = a.val4
    prodArray.append(prod)
}
