使用Alamofire获取带有GET请求和参数的JSON结果

这是我的url String with paramaters。 http://api.room2shop.com/api/product/GetProducts?categoryId=22&filter=2&pageNumber=1我通过它获取我的JSON数据。我有AFWrapper.swift文件,其中我已经为GETrequest定义了函数。

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)
            }


           }
        }
}

现在我在我的ViewController.swift文件中调用此函数。

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。

谁能告诉我我做错了什么?我已经链接了这个链接,但没有弄错。 URL Encode Alamofire GET params with SwiftyJSON

我认为您应该删除“encoding:ParameterEncoding.JSON”的参数,如下所示:

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)
        }


}

您的requestGETURL应该是那样的

    func requestGETURL(strURL: String, params: [String:String]?, success: (AnyObject?) -> Void, failure: (NSError) -> Void) {
    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)
        }


    }
}

您的问题出在params,它应该是[String:String]字典。您也不必声明编码encoding:ParameterEncoding.JSON

使用此代码。它正在检索在JSON中正确解析的响应。

使用 Alamofire v3.0 +

Alamofire.request(.GET, "http://api.room2shop.com/api/product/GetProducts?categoryId=22&filter=2&pageNumber=1")
        .responseJSON { response in
            debugPrint(response)

            switch response.result {
            case .Success(let JSON):
                print(JSON)
            case .Failure(let error):
                print(error)
            }
    }

修改 接受GET类型服务的参数:

Alamofire.request(.GET, "https://httpbin.org/get", parameters: ["foo": "bar"])
     .responseData { response in
         print(response.request)
         print(response.response)
         print(response.result)
      }

在这种情况下,请尝试不要操纵您的URL字符串,并按照这样的方式发送所有参数。
