我正在尝试使用一个api响应,它在postman中很好地返回,但是当我用swift打印它时,它在行尾有分号
我已经尝试了各种方法和选择来改变请求和处理响应,但都没有结果。为什么分号在那里?
*******代码段******

let todosEndpoint: String = "https://url:3000/api/v1/somestring?
query=$filter%3DUPC%20eq%20'somenumber'"
    guard let todosURL = URL(string: todosEndpoint) else {
        print("Error: cannot create URL")
        return
    }
    var todosUrlRequest = URLRequest(url: todosURL)
todosUrlRequest.httpMethod = "GET"

todosUrlRequest.setValue("application/json", forHTTPHeaderField:
"Content-Type")

todosUrlRequest.setValue("Bearer "+token, forHTTPHeaderField: "Authorization")


let task = URLSession.shared.dataTask(with: todosUrlRequest) { (data, response, error) in
guard let dataResponse = data,
    error == nil else {
        print(error?.localizedDescription ?? "Response Error")
    return }

    do{
        let myJson = try JSONSerialization.jsonObject(with: data!) as? NSDictionary

        print(myJson!)

********结果*****
Desired Results:
{
"@odata.context": "https://api.url.com/v1/$metadata#Products",
"value": [
    {
        "ASIN": null,
        "Height": null,
        "Length": null,
        "Width": null,
        "Weight": null,
        "Cost": null,
        "Margin": null,
        "RetailPrice": null,
        "StartingPrice": null,
        "ReservePrice": null,
         }
    ]
}


Actual Results:
{
"@odata.context" = "https://api.url.com/v1/$metadata#Products";
value =     (
            {
        ASIN = "<null>";
        BlockComment = "<null>";
        BlockedDateUtc = "<null>";
        Brand = BAZZILL;
        BundleType = None;
        BuyItNowPrice = "0.99";
        CategoryCode = "<null>";
        CategoryPath = "<null>";
        Classification = "<null>";
        Condition = "<null>";
        Cost = "<null>";
        }
    );
}

最佳答案

如果您将JSON序列化为字典,因为您正在执行以下操作:

let myJson = try JSONSerialization.jsonObject(with: data!) as? NSDictionary
print(myJson!)

这意味着您可以访问每个字段,例如:let comment = myJson["BlockComment"]
但是,最好序列化为结构:
struct Product: Codable {
    let asin: String?
    let blockComment: String?
    let brand: String?
    let buyItNowPrice: Float?
    let cost: Float?

    enum CodingKeys: String, CodingKey {
        case asin = "ASIN"
        case blockComment = "BlockComment"
        case brand = "Brand"
        case buyItNowPrice = "BuyItNowPrice"
        case cost = "Cost"
    }
}

然后你会:
let product = try JSONDecoder().decode(Product.self)
print(product.cost)
print(product.brand)
//etc..
