swift - Alamofire 的格式化字典

Question

这个问题更多的是关于 Swift & 和字典而不是 Alamofire 本身

我需要通过网络服务创建记录，我使用的是 Alamofire。出于某种原因，我的报价比预期的要多，网络服务拒绝了我的电话

如果我通过 curl 模拟调用，web 服务接收:

{"records"=>[{"id"=>"2", "node"=>{"children"=>[{"specifications"=>"Specs", "description"=>"Fee", "line_item"=>{"sale_price"=>123.4, 
"amount"=>1, "vat_percentage"=>21, "unit_price"=>99.5}}]}}], "action"=>"create", "collection"=>"invoices", "controller"=>"api/v2/api"}

如果我在我的应用程序中通过 Alamofire 进行调用，网络服务会收到:

{"records"=>[{"id"=>"2", "node"=>{"children"=>[{"specifications"=>"Specs", "description"=>"Fee", "line_item"=>{"sale_price"=>"123.4", 
"amount"=>"1", "vat_percentage"=>"21", "unit_price"=>"99.5"}}]}}], "action"=>"create", "collection"=>"invoices", "controller"=>"api/v2/api"}

如您所见，每个数字都用引号括起来(例如，“99.5”与 99.5，导致网络服务翻转。

我调整了一下，但找不到如何在 Swift 中解决这个问题。我为 Alamofire 创建负载的方式是:

let jsonObject: [String: AnyObject] = [
            "id": id as AnyObject,
            "node" : [
                "children": [[
                    "description" : lineDescription,
                    "specifications" : lineSpecifications,
                    "line_item" : [
                        "amount" : 1,
                        "unit_price" : feePrice,
                        "sale_price" : feePrice,
                        "vat_percentage" : 21

                    ]
                ]] as AnyObject
            ] as AnyObject
        ]
let parameters = ["records" : [jsonObject as AnyObject]]    

Alamofire.request(urlPath, method: .post, parameters: parameters, headers: ["X-API-KEY": apiKey, "Content-type application":"json", "Accept application" : "json"]).responseString() {

            response in switch (response.result) {

blah blah
}

其中变量 lineDescription 和 lineSpecifications 是字符串，feePrice 是 Double

如评论中所述，我需要为请求添加编码。要关闭问题并显示格式更友好的解决方案，请使用此答案:

Alamofire.request(urlPath, method: .post, parameters: parameters, headers: ["X-API-KEY": apiKey, "Content-type application":"json", "Accept application" : "json"]).responseString() {

应该是:

Alamofire.request(urlPath, method: .post, parameters: parameters,  encoding: JSONEncoding.default, headers: ["X-API-KEY": apiKey, "Content-type application":"json", "Accept application" : "json"]).responseString() {
