使用GET请求和Alamofire参数获取JSON结果

问题描述

这是我的带有参数的URL字符串。
，通过它我可以获取JSON数据。我有一个AFWrapper.swift文件，其中定义了GETrequest函数。

This is my url String with paramaters.http://api.room2shop.com/api/product/GetProducts?categoryId=22&filter=2&pageNumber=1 through which I am getting my JSON data. I have AFWrapper.swift file in which I have defined function for GETrequest.

import UIKit
import Alamofire
import SwiftyJSON

class AFWrapper: NSObject {

    class func requestGETURL(strURL: String, params : [String : AnyObject]?, success:(JSON) -> Void, failure:(NSError) -> Void) {
        Alamofire.request(.GET, strURL, parameters: params, encoding: ParameterEncoding.JSON).responseJSON { (responseObject) -> Void in

            print(responseObject)

            if responseObject.result.isSuccess {
                let resJson = JSON(responseObject.result.value!)
                success(resJson)
            }
            if responseObject.result.isFailure {
                let error : NSError = responseObject.result.error!
                failure(error)
            }


           }
        }
}

现在我在ViewController.swift文件中调用此函数。

Now I am calling this function in my ViewController.swift file.

let strURL = "http://api.room2shop.com/api/product/GetProducts"
    let param = ["categoryId": "22", "filter": "2", "pageNumber": "1"]
    AFWrapper.requestGETURL(strURL, params: param, success: {
        (JSONResponse) -> Void in

        if let resData = JSONResponse["ProductList"].arrayObject {
            for item in resData {
                self.TableData.append(datastruct(add: item as! NSDictionary))
            }

        do
        {
            try self.read()
        }
        catch
        {
        }
        self.do_table_refresh()
    }

}) {
    (error) -> Void in
    print(error)
}

但它没有给我任何回应，并给我这个错误。

but it is not giving me any response and giving me this error.

有人可以告诉我我在做什么错吗？我已经找到了此链接，但没有弄错。

Can anyone tell me what am I doing wrong? I have seached this link but not getting what is wrong. URL Encode Alamofire GET params with SwiftyJSON

推荐答案

我认为您应该删除 encoding：ParameterEncoding.JSON的参数，例如：

i think you should remove the parameter of "encoding: ParameterEncoding.JSON",like this:

Alamofire.request(.GET, strURL, parameters: params).responseJSON { (responseObject) -> Void in

        print(responseObject)

        if responseObject.result.isSuccess {
            let resJson = JSON(responseObject.result.value!)
            success(resJson)
        }
        if responseObject.result.isFailure {
            let error : NSError = responseObject.result.error!
            failure(error)
        }


}
