Use moya to send POST request with json but no http body send

[lzz212]

I use moya 15 to do network jobs.
And I need send a http request with json but I use the Charles to get the http package and find that no body.

public var task: Task {
    switch self {
    case let .loginGetSMS(phone):
        var params = [String: Any]()
        params["phone"] = phone
        var urlParams = [String: Any]()
        urlParams["phone"] = phone

// return .requestParameters(parameters: params, encoding:JSONEncoding.default)
return .requestCompositeParameters(bodyParameters: params,
bodyEncoding: JSONEncoding.default,
urlParameters: [:])

.....
I use these two ways to send both no use.
But when I change the encoding from JSONEncoding to URLEncoding server can see the body but not json
