URL使用SwiftyJSON编码Alamofire GET参数

本文介绍了URL使用SwiftyJSON编码Alamofire GET参数的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我试图让Alamofire在GET请求中发送以下参数，但它发送乱码：

I am trying to have Alamofire send the following parameter in a GET request but it's sending gibberish:

filters={"$and":[{"name":{"$bw":"duke"},"country":"gb"}]} //www.example/example?filters={"$and":[{"name":{"$bw":"duke"},"country":"gb"}]} //Obviously URL encoded

这是我的代码：

let jsonObject = ["$and":[["name":["$bw":string], "country":"gb"]]] let json = JSON(jsonObject) print(json)

输出

{$ and：[ {name：{$ bw：duke}， country：gb} ] }

{ "$and" : [ { "name" : { "$bw" : "duke" }, "country" : "gb" } ] }

这是我的params请求：

This is my params request:

let params = ["filters" : json.rawValue, "limit":"1", "KEY":"my_key"]

这是AlamoFire发送的内容：

This is what AlamoFire is sending:

KEY=my_key& filters[$and][][country]=gb& filters[$and][][name][$bw]=duke& limit=1

正如您所见，filter参数完全混乱。我做错了什么？

As you can see the filter parameter is a complete mess. What am I doing wrong?

推荐答案

默认情况下，Alamofire使用POST正文中的参数列表对参数进行编码。尝试将编码更改为 JSON 。这样，Alamofire会将字典序列化为您想要的JSON字符串：

By default Alamofire encodes the parameters using Parameter List in the POST body. Try changing the encoding to JSON. This way Alamofire will serialize the dictionary as a JSON string as you expect:

let parameters = [ "foo": [1,2,3], "bar": [ "baz": "qux" ] ] Alamofire.request(.POST, "httpbin/post", parameters: parameters, encoding: .JSON) // HTTP body: {"foo": [1, 2, 3], "bar": {"baz": "qux"}}

或使用您的代码：

let string = "duke" let jsonObject = ["$and":[["name":["$bw":string], "country":"gb"]]] let json = JSON(jsonObject) let params = ["filters" : json.rawValue, "limit":"1", "KEY":"my_key"] Alamofire.request(.POST, "httpbin/post", parameters: params, encoding: .JSON) .responseString(encoding: NSUTF8StringEncoding) { request, response, content, error in NSLog("Request: %@ - %@\n%@", request.HTTPMethod!, request.URL!, request.HTTPBody.map { body in NSString(data: body, encoding: NSUTF8StringEncoding) ?? "" } ?? "") if let response = response { NSLog("Response: %@\n%@", response, content ?? "") } }

获取输出：

Request: POST - httpbin/post {"filters":{"$and":[{"name":{"$bw":"duke"},"country":"gb"}]},"limit":"1","KEY":"my_key"}

编辑：GET参数中的URL编码JSON

如果要在GET参数中发送URL编码的JSON，则必须先生成JSON字符串，然后将其作为参数字典中的字符串传递：

If you want to send a URL-Encoded JSON in the GET parameters you have to generate first the JSON string and then pass it as a string in your parameters dictionary:

SWIFT 1

let string = "duke" let jsonObject = ["$and":[["name":["$bw":string], "country":"gb"]]] let json = JSON(jsonObject) // Generate the string representation of the JSON value let jsonString = json.rawString(encoding: NSUTF8StringEncoding, options: nil)! let params = ["filters" : jsonString, "limit": "1", "KEY": "my_key"] Alamofire.request(.GET, "httpbin/post", parameters: params) .responseString(encoding: NSUTF8StringEncoding) { request, response, content, error in NSLog("Request: %@ - %@\n%@", request.HTTPMethod!, request.URL!, request.HTTPBody.map { body in NSString(data: body, encoding: NSUTF8StringEncoding) ?? "" } ?? "") if let response = response { NSLog("Response: %@\n%@", response, content ?? "") } }

SWIFT 2

let string = "duke" let jsonObject = ["$and":[["name":["$bw":string], "country":"gb"]]] let json = JSON(jsonObject) // Generate the string representation of the JSON value let jsonString = json.rawString(NSUTF8StringEncoding)! let params = ["filters" : jsonString, "limit": "1", "KEY": "my_key"] Alamofire.request(.GET, "httpbin/post", parameters: params) .responseString(encoding: NSUTF8StringEncoding) { request, response, result in NSLog("Request: %@ - %@\n%@", request!.HTTPMethod!, request!.URL!, request!.HTTPBody.map { body in NSString(data: body, encoding: NSUTF8StringEncoding) ?? "" } ?? "") switch result { case .Success(let value): NSLog("Response with content: %@", value) case .Failure(let data, _): NSLog("Response with error: %@", data ?? NSData()) } }

SWIFT 3和Alamofire 4.0

let string = "duke" let jsonObject = ["$and":[["name":["$bw":string], "country":"gb"]]] let json = JSON(jsonObject) // Generate the string representation of the JSON value let jsonString = json.rawString(.utf8)! let params = ["filters" : jsonString, "limit": "1", "KEY": "my_key"] Alamofire.request("httpbin/post", method: .get, parameters: params) .responseString { response in #if DEBUG let request = response.request NSLog("Request: \(request!.httpMethod!) - \(request!.url!.absoluteString)\n\(request!.httpBody.map { body in String(data: body, encoding: .utf8) ?? "" } ?? "")") switch response.result { case .success(let value): print("Response with content \(value)") case .failure(let error): print("Response with error: \(error as NSError): \(response.data ?? Data())") } #endif }

这会生成一个带有以下URL的GET请求：

This generates a GET request with the following URL:

httpbin/post?KEY=my_key&filters=%7B%22%24and%22%3A%5B%7B%22name%22%3A%7B%22%24bw%22%3A%22duke%22%7D%2C%22country%22%3A%22gb%22%7D%5D%7D&limit=1

该网址已解码为：

httpbin/post?KEY=my_key&filters={"$and":[{"name":{"$bw":"duke"},"country":"gb"}]}&limit=1
