ios - 如何在 Alamofire 请求 swift 3 中传递 JSON 对象

Question

我正在使用 Alamofire API 进行服务调用。到目前为止，GET 方法运行良好。现在我需要执行一个 PUT 请求。它还接受这种类型的主体参数。

{
"LeaveEntryCode":0,
"RequestId":0,
"EmployeeCode":17227,
"LeaveYear":2017,
"LeaveTypeCode":1,
"LeaveReasonCode":1,
"BaseType":"ess",
"StartDate":"2017-06-16T00:00:00",
"EndDate":"2017-06-16T00:00:00",
"NoOfDays":1.0,
"StartDateSession":"full",
"EndDateSession":"full",
"PreApproved":false,"ForDate":"1901-01-01T00:00:00",
"Remarks":"I have to attend for a wedding of my close relatives",
"CoveringPersonCode":0,
"RequestStatus":"P",
"Deleted":false,
"Status":false,
"CreatedBy":0,
"CreatedDate":"0001-01-01T00:00:00",
"UpdatedBy":0,
"UpdatedDate":"0001-01-01T00:00:00",
"DeletedBy":0,
"DeletedDate":"0001-01-01T00:00:00",
"ModuleId":2,
"ObjectId":20,
"StartDateString":"06/16/2017",
"EndDateString":"06/16/2017",
"LeaveDayList":["06/16/2017-FH,06/16/2017-SH"],
"SystemLeaveTypeCode":"ANN",
"LeaveTypeName":"ANNUAL",
"Employee":null,
"LieuDayList":null,
"BaseLeaveType":"ANN",
"CoveringPersonName":"",
"LeaveReasonName":"Personal",
"DocumentSource":"LEAVE",
"AttachedDocument":null
}

我创建了一个 [String:Any] 对象并分配给以下请求中的 parameters。

But I got an error called Extra argument 'method' in the call.

但是如果我将它分配为 ["":""] 错误就会消失。我该如何解决这个问题？请帮助我。

Alamofire.request(urlString, method: method, parameters: parameters, encoding: JSONEncoding.default, headers: headerToken)

更新

var dictionary:[String:String]!
dictionary=[
            "LeaveEntryCode":"0",
            "RequestId":dm.strReqID,
            "EmployeeCode":dm.strEmpCode,
            "LeaveYear":dm.selectedYear,
            "LeaveTypeCode":dm.selectedLeaveTypeCode,
            "BaseType":"ess",
            "StartDate":dm.startDate,
            "EndDate":dm.endDate,
            "NoOfDays":dm.noOFDays,
            "StartDateSession":dm.startDateSession,
            "EndDateSession":dm.endDateSession,
            "RequestStatus":"P",
            "PreApproved":"0",
            "ForDate":"01/01/1901",
            "Remarks":comment,
            "CoveringPersonCode":dm.strcoveringPersonCode,
            "LeaveDayList":strDayLvList,
            "BaseLeaveType":dm.selectedLeaveTypeCode,
            "LeaveReasonCode":dm.selectedReasontypeCode,
            "AttachedDocument":"null"
            ]

Answer 1

你在调用中遇到一个名为 Extra argument 'method' 的错误，这是由于 header 引起的，

尝试将 header 传递为 nil 或如下所示:

//Here param equals to your dictionary as [String :Any]

//Pass Headers as Dictionary as well.

     Alamofire.request("", method: .post, parameters: param, encoding: JSONEncoding.default, headers:["" : ""])

它对我有用。
