Question

我试图使用alamofire库，但我有一个问题，我试图将下一个jsonString添加到请求的正文，它总是给我相同的400状态代码，有人可以帮助我，这是字符串和我的代码：

Json String：{＆＃34;时刻＆＃34;：{＆＃34;名称＆＃34; ：＆＃34; hola＆＃34;，＆＃34;开始＆＃34; ：＆＃34; 12-5-2005 0：0＆＃34;，＆＃34; end＆＃34; ：＆＃34; 22-4-2007 0：0＆＃34;，＆＃34;存储＆＃34; ：false}}

这是我的实际代码，谢谢

                let jsonString = "{\"moment\":{" + "\"name\" : " + "\"" + nombre + "\"" + ",\"begin\" : \"" + fechaIni + "\"," +
                    "\"end\" : " + "\"" + fechaFin  + "\"" + "," + "\"stored\" : false" + "}" + "}"

                let request = NSMutableURLRequest(URL: NSURL(string: "http://whatmatters.deploy-cd.com/api/me/moments.json")!)
                request.HTTPMethod = "POST"
                request.setValue("application/json", forHTTPHeaderField: "ContentType")
                request.HTTPBody = jsonString.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
                Alamofire.request(request).authenticate(user: user, password: pass)
                    .response { resp in
                        print(resp)

                }

<强>更新你必须在json中序列化你的数据

这里应该是什么样子：

let jsonString = "{\"moment\":{" + "\"name\" : " + "\"" + nombre + "\"" + ",\"begin\" : \"" + fechaIni + "\"," +
                "\"end\" : " + "\"" + fechaFin  + "\"" + "," + "\"stored\" : false" + "}" + "}"

            let request = NSMutableURLRequest(URL: NSURL(string: "http://whatmatters.deploy-cd.com/api/me/moments.json")!)
            request.HTTPMethod = "POST"
            request.setValue("application/json", forHTTPHeaderField: "ContentType")
            let stringData = jsonString.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
            do {
        let jsonData:NSData? = try NSJSONSerialization.JSONObjectWithData(stringData!, options: .AllowFragments) as? NSData
        request.HTTPBody = jsonData
    } catch let caught as NSError {
        print(caught)
    }
            Alamofire.request(request).authenticate(user: user, password: pass)
                .response { resp in
                    print(resp)

            }

我这样做以发送json Post参数的方法是将参数放在Dictionary中，如下所示：

let parameters  = [
                "moment" : [
                    "name"  : nombre,
                    "begin" : fechaIni,
                    "end"   : fechaFin,
                    "stored"   : false,

                ]]

所以所有的代码都是这样的

 var request = NSMutableURLRequest(URL: NSURL(string: "http://whatmatters.deploy-cd.com/api/me/moments.json")!)
 request.HTTPMethod = "POST"
 request.setValue("application/json", forHTTPHeaderField: "ContentType")
 // request.HTTPBody = jsonString.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
 let parameters = [
                "moment" : [
                    "name"  : nombre,
                    "begin" : fechaIni,
                    "end"   : fechaFin,
                    "stored"   : false,

                ]]

request =  Alamofire.ParameterEncoding.JSON.encode(request, parameters: parameters).0
Alamofire.request(request).authenticate(user: user, password: pass)
                .response { resp in
                    print(resp)
            }

注意：请注意字典值数据类型和json中所需的数据类型，即如果您需要所有json值a String，请将字典值转换为{ {1}}

如果您使用字典而不是字符串，可以在Alamofire文档中找到简短的解决方案：

https://github.com/Alamofire/Alamofire#post-request-with-json-encoded-parameters

public static void NewRecords()
        {
            using (var stageContext = new StagingTableDataContext())
            {
                using (var destinationContext = new DestinationTableDataContext())
                {
                    var allProjectNames = destinationContext.THEOPTIONs.Select(u => u.NAME).ToList(); 
                    var deltaList = stageContext.ProjectMasters.ToList().Where(u => !allProjectNames.Contains(u.Finance_Project_Number)).ToList();

                    deltaList.ForEach(u => u.Processing_Result = 0);
                    deltaList.ForEach(u => u.Processing_Result_Text = "UNIQUE");

                }
                stageContext.SubmitChanges();
            }
        }
