Question

我一直在关注本教程：https://devdactic.com/parse-json-with-swift/ 并遵循了每条指令。但我只是不能使http post请求工作，因为看起来我的api服务无法获取所请求的参数。所以这是我的httppost请求方法：

private func makeHTTPPostRequest(path: String, body: [String: AnyObject], onCompletion: ServiceResponse) {
        let request = NSMutableURLRequest(URL: NSURL(string: path)!)

        // Set the method to POST
        request.HTTPMethod = "POST"

        do {
            // Set the POST body for the request
            let jsonBody = try NSJSONSerialization.dataWithJSONObject(body, options: .PrettyPrinted)

            request.HTTPBody = jsonBody
            let session = NSURLSession.sharedSession()

            let task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in
                if let jsonData = data {
                    let json:JSON = JSON(data: jsonData)

                    onCompletion(json, nil)

                } else {

                    onCompletion(nil, error)
                }

            })
            task.resume()

        } catch {
            // Create your personal error
            onCompletion(nil, nil)
        }
    }

然后我创建了一个函数来调用它：

func registerNewUser(email: String,url: String, onCompletion: (JSON) -> Void) {

        let route = baseURL + url

        print(route)

        let postItems:[String: String] = ["email": email]
        print("postitems",postItems)



        makeHTTPPostRequest(route, body: postItems, onCompletion: { json, err in

            onCompletion(json as JSON)

            print("response",json)

        })

    }

然后从注册控制器调用它：

func requestSignUp()
    {
        if((emailField.text?.isEmpty) == false)
        {
        //performSegueWithIdentifier("showVerification", sender: signUpBtn)

            let url = "user/signup"
            RestApiManager.sharedInstance.registerNewUser(emailField.text! as String, url: url as String,  onCompletion: {
                (json: JSON) in if let results = json[0].array {
                    for entry in results {

                        print(entry)

                    }
                }
            })

        }
    }

打印显示注册用户下的帖子格式为：

postitems [“email”：“dasdsd”]

我的服务回复显示了这一点：

response {
  "responseData" : {

  },
  "responseStat" : {
    "status" : false,
    "isLogin" : false,
    "requestError" : [

    ],
    "msg" : "The email field is required.",
    "extra" : {

    }
  }
}

电子邮件字段参数为电子邮件，成功提交后会显示如下内容：

{
  "responseStat": {
    "status": true,
    "isLogin": false,
    "msg": "Successfully Registered an, your password has been sent to your email",
    "requestError": [],
    "extra": {}
  },
  "responseData": ""
}

Answer 1

在 makeHTTPPostRequest 中添加此行使其正常工作：

request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")

Answer 2

您可以在Alamofire旁边使用SwiftyJSON和Ease：

static func requestToSendObject(value: YOUROBJECT) {
    let url = NSURL(string: "http://google.com")!
    let params: [String: AnyObject] = [
        "object_key" : value
    ]
    Alamofire.request(.POST, url, parameters: params, encoding: .JSON, headers: nil).responseJSON {
        if let data = response.result.value {
            let responseJSON = JSON(data)
            // Use the responseJSON
        }
    }
}
