Question

您好我正在尝试给阵列中称为“插件”的alamofire参数...数组可以包含3个或X个项目。我试图使用FOR循环到广告词典到另一个另一组项目，但是...它只显示最后一个...它似乎覆盖了前一个。我尝试了所有我知道的东西......甚至尝试使用SwiftyJSON框架....但是alamofire只采用纯字典类型。

    let itemsArr = ["Skirts", "Coat", "Shirt"]
    let priceArr = ["7.00", "7.00", "2.90"]
    let quantityArr = ["2", "5", "1"]

    let personalInfo: [String : Any] = [
        "phone" : phone,
        "notes" : descNote
    ]

    var para: [String: Any] = [
        "pieces" : pieces,
        "personal_info" : personalInfo,
        "payment_method" : paymentMethod
    ]

    for i in 0..<itemsArr.count {
        let addons: [String: Any] = [
            "name":itemsArr[i],
            "price":priceArr[i],
            "quantity":quantityArr[i]
        ]
        print(addons)
        para["addons"] = addons
    }

我需要这样的东西

{
  "pieces": 12,
  "personal_info": {
    "phone": "+420783199102",
    "notes": "Plz be fast, I need to play Game of War"
  },
  "payment_method": "cod",
  "addons": [
    {
      "name": "Select day Tue",
      "price": 3.5,
      "quantity": 1
    },
    {
      "name": "Select day Thu",
      "price": 3.5,
      "quantity": 1
    }
  ]
}

你的问题是在循环中你用单个结果覆盖每次迭代的变量。这就是为什么只有最后一个留给你的原因。你应该做的是：

//create an array to store the addons outside of the loop
var addons: [[String: Any]] = []
for i in 0..<itemsArr.count {
    let addon: [String: Any] = [
        "name":itemsArr[i],
        "price":priceArr[i],
        "quantity":quantityArr[i]
    ]
    //append a single addon to our array prepared before the loop
    addons.append(addon)
}
//once we gathered all addons, append results to `para` dictionary
para["addons"] = addons
