【中文标题】如何使用 Alamofire 发布 SwiftyJSON？【英文标题】：How to post SwiftyJSON with Alamofire? 【发布时间】：2017-07-19 04:26:37 【问题描述】：我想通过 Alamofire 发布 JSON。
但我不太确定我该如何处理它。
我的swiftyJSON 在一个数组中作为我的
如何将 JSON 数组编码为字典对象？适合
Alamofire's Parameters?
urlRequest = try JSONEncoding.default.encode(urlRequest, with: location)
我的 JSON 示例如下所示：
"[\n acc = accuracy;\n lat = lat;\n long = long;\n type = type;\n, \n acc = accuracy;\n lat = lat;\n long = long;\n type = type;\n, \n acc = accuracy;\n lat = lat;\n long = long;\n type = type;\n, \n acc = accuracy;\n lat = lat;\n long = long;\n type = type;\n, \n acc = accuracy;\n lat = lat;\n long = long;\n type = type;\n]"
【问题讨论】：
你试过了吗，Alamofire.request("httpbin.org/post", method: .post, parameters: parameters, encoding: JSONEncoding.default)？ 【参考方案1】：诀窍是您需要将其转换为字典。 示例 sn-p 如下：
```
// let assume swiftyJSON is a SwiftyJSON object (JSON)
if let data = swiftyJSON.rawString()!.data(using: .utf8)
do
let json = try JSONSerialization.jsonObject(with: data, options: []) as! [String: Any]
Alamofire.request(url, method: .post, parameters: json, encoding: JSONEncoding.default, headers: headers).responseJSON response in
debugPrint(response)
catch
print("JSONSerialization error")
```
【讨论】：
【参考方案2】：First add SwiftJSON to your project then
class func requestPOSTURL(serviceName:String,parameters: [String:Any]?, completionHandler: @escaping (JSON?, NSError?) -> ())
let headersSet: HTTPHeaders = [
"Authorization":GlobalAccesstoken,
"Accept": "application/json"
]
Alamofire.request(serviceName, method: .post, parameters: parameters, encoding: URLEncoding.default, headers: headersSet).responseJSON
(response:DataResponse<Any>) in
switch(response.result)
case .success(_):
if let data = response.result.value
let json = JSON(data)
completionHandler(json,nil)
break
case .failure(_):
completionHandler(nil,response.result.error as NSError?)
break
AFWrapper.requestPOSTURL(serviceName: LapiUrl+"get_profile", parameters: params) (response:JSON?, error:NSError?) in
if error != nil
print(error!)
return
if response == nil
return
print(response!)
var distRespoce = response!.dictionary?["response"]?.array?[0]
if (distRespoce?["status"].string == "true")
let distuserData = distRespoce!.dictionary?["user_data"]
else
print("no")
Try above code ..
【讨论】：
【参考方案3】：你可以这样做：-
Alamofire.request(urlString, method: .post, parameters: paramData, encoding:JSONEncoding.default, headers: nil).responseJSON (response:DataResponse<Any>) in
switch(response.result)
case .success(_):
if response.result.value != nil
do
var dict : NSDictionary = try JSONSerialization.jsonObject(with: response.data!, options: JSONSerialization.ReadingOptions.mutableContainers) as! NSDictionary
print(dict)
dict = UtilityClass.removeNullFromResponse(response: response.result.value! as! NSDictionary)
self.dataBlock(dict,nil)
catch
UtilityClass.hideHudLoading()
break
case .failure(_):
if response.result.error != nil
print(response.result.error!)
UtilityClass.hideHudLoading()
break

嗨 @user2537789 我正在尝试发布:)【参考方案4】：简单获取邮政编码，易于使用、维护和理解
下面是pod，需要用到我的json解析代码。
#Network manager related
pod 'Alamofire', :git => 'https://github.com/Alamofire/Alamofire.git', :tag => ‘4.0.1’
pod 'AlamofireNetworkActivityIndicator', '~> 2.0'
pod 'AlamofireObjectMapper', '~> 4.0.0'
pod 'SVProgressHUD', :git => 'https://github.com/SVProgressHUD/SVProgressHUD.git'
pod 'Reachability', '~> 3.2'
pod 'SwiftyJSON', '~> 3.0.0'
pod 'ObjectMapper', '~> 2.0'
pod 'SDWebImage', '~> 3.8'
在这里，您可以在视图控制器中调用 API。
