如何在 Moya 请求中通过 POST 请求传递原始 JSON 正文答案

【问题标题】：How to pass raw JSON Body with POST request in Moya request如何在 Moya 请求中通过 POST 请求传递原始 JSON 正文

【问题描述】：

我正在使用Moya 库在我的项目中调用 api。

现在是在正文中通过 POST 请求传递原始 json 对象（将多个对象作为单个对象）所需的 API 之一。它在邮递员中工作正常。

查看下面的截图，

还检查原始正文 json，

    {
            "geometry": {
                "location": {
                    "lat": "22.7195687",
                    "lng": "75.8577258"
                }
            },
            "icon": "https://maps.gstatic.com/mapfiles/place_api/icons/v1/png_71/geocode-71.png",
            "name": "Indore",
            "photos": [
                {
                    "photo_reference": "Aap_uECCOLowEnJ2yBUzF0nwRjV5jBx2_JWsofVosuLVvlr-ClIMHNR5-QGIe4phK-3_Bj_laHD_XH_LvlmGDzm33KvxuO1XzaZocxTLOVUdSGI3_otXvpx_FbuzmwiibZiylQEMkekTLKbLdXjK8H3w10nOcoJE-InDVvf5P7Cvyum_kk9k"
                }
            ],
            "place_id": "ChIJ2w1BG638YjkR9EBiNdrEbgk",
            "reference": "ChIJ2w1BG638YjkR9EBiNdrEbgk",
            "types": [
                "locality",
                "political"
            ],
            "vicinity": "Indore"
        },
        {
            "geometry": {
                "location": {
                    "lat": "22.7429365",
                    "lng": "75.8867267"
                }
            },
            "icon": "https://maps.gstatic.com/mapfiles/place_api/icons/v1/png_71/generic_business-71.png",
            "name": "Visual Maker",
            "photos": [
                {
                    "photo_reference": "Aap_uED84yCmvAirxt-dSdPPSE3O_eBSunEiSOM1Uzr0kNNMiJBVvPtBuCuwck2Ek0CDg7S8JP09Iva3Rjhq63O1Tyql_CTeMRF_GWC19QfZUFwwvadcRbfLWo6Wqn4ndCTCh5A6RV212PJcB0HZqe6YV7FphiV_XjkP9pCvk5JLDKNrvOXz"
                }
            ],
            "place_id": "ChIJGwLEIlr9YjkRnr8uTQiQ8KU",
            "reference": "ChIJGwLEIlr9YjkRnr8uTQiQ8KU",
            "types": [
                "university",
                "general_contractor",
                "point_of_interest",
                "establishment"
            ],
            "vicinity": "behind Anop Cinema, K/112, LIG Colony, Indore"
        },
 }

这是两个对象，但可以是多个对象

下面是我的Moya api调用类。

import Moya
import Result
import Alamofire
import UIKit

private func JSONResponseDataFormatter(_ data: Data) -> Data {
    do {
        let dataAsJSON = try JSONSerialization.jsonObject(with: data)
        let prettyData =  try JSONSerialization.data(withJSONObject: dataAsJSON, options: .prettyPrinted)
        return prettyData
    } catch {
        return data // fallback to original data if it can't be serialized.
    }
}

private extension String {
    var urlEscaped: String {
        return self.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed)!
    }
}

let MyAPIProvider = MoyaProvider<EBabuAPI>( plugins: [VerbosePlugin(verbose: true)])

enum MyAPI {
    case topPlaceVibeAvg(geometry : [Any], icon:[String], name:[String], photos:[Any], placeIds:[String], reference:[String], types:[Any], vicinity:[Any])
}

extension EBabuAPI: TargetType {
    
    var headers: [String : String]? {
        switch self {
        default:
            return ["Authorization": SharedPreference.authToken()]
        }
    }
    
    var baseURL : URL {
        return URL(string: Constants.API.baseURL)! //["Authorization": "Bearer \(Helpers.userToken())"]
    }
    
    var path: String {
        switch self {
        case .topPlaceVibeAvg:
            return "places/topPlaceVibeAvg"
        }
    }
    
    public var method: Moya.Method {
        switch self {
        case .topPlaceVibeAvg :
            return .post
        }
    }
    
    var sampleData: Data {
        return "".data(using: .utf8)!
    }
    
    var task: Task {
        switch self {
        case .topPlaceVibeAvg(let geometry,let icon, let name, let photos, let placeIds, let reference, let types, let vicinity):
            return .requestParameters(parameters: ["geometry":geometry, "icon":icon, "name":name, "photos":photos, "place_id":placeIds, "reference":reference, "types":types, "vicinity":vicinity], encoding: JSONEncoding.default)
        }
    }
    
    func dicToStrig(data : AnyObject) -> String {
        do {
            let jsonData = try JSONSerialization.data(withJSONObject: data, options: [])
            let jsonString = String(data: jsonData, encoding: String.Encoding.ascii)!
            return  jsonString
            
        } catch {
            //handle error
            print("error",error)
        }
        return ""
    }
    
    var parameterEncoding: ParameterEncoding {
        switch self {
            
        default:
            return JSONEncoding.default
        }
    }
}

struct JsonArrayEncoding: Moya.ParameterEncoding {
    
    public static var `default`: JsonArrayEncoding { return JsonArrayEncoding() }
    
    public func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
        var req = try urlRequest.asURLRequest()
        let json = try JSONSerialization.data(withJSONObject: parameters!["jsonArray"]!, options: JSONSerialization.WritingOptions.prettyPrinted)
        req.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
        req.httpBody = json
        return req
    }
}

正如每个人都可以看到上面的代码，我正在尝试调用 topPlaceVibeAvg api，并成功调用他们的键和值 api，但它没有提供与邮递员屏幕截图相同的正确响应。

这里是 api 响应： { 数据 = ( ); message = "平均获取成功！"; 状态码 = 200; 成功 = 1; }

我在下面使用ViewModel(placesViewModel) 来调用api。

    var icon = [String]()
    var name = [String]()
    var name = [Any]()
    var placeIds = [String]()
    var reference = [String]()
    var testTypes = [Any]()
    var vicinity = [Any]()
    
    var geometry = [Any]()
    var photos = [Any]()

func topPlaceVibeAvg(_ completion: @escaping ((JSONDictionary) -> ())) {
        if !isPullToRefresh {  Loader.show("Looking around....") }
        
        APIController.makeRequest(.topPlaceVibeAvg(geometry: geometry, icon: icon, name: name, photos: photos, placeIds: placeIds, reference: reference, types: types, vicinity: vicinity)) { (data, error) in
            Loader.hide()
            if error == nil {
                completion(data!)
            } else {
                ToastAndAlertManager.showToastWithTitle((error?.desc)!, colorCode: ToastColor.error.rawValue)
            }
        }
    }

这是我的ViewController api 类

    placesViewModel.geometry = self.nearByPlacesArray.map{$0.geometry}
    placesViewModel.icon = self.nearByPlacesArray.map{$0.icon}
    placesViewModel.name = self.nearByPlacesArray.map{$0.name}
    placesViewModel.photos = self.nearByPlacesArray.map{$0.photos}
    placesViewModel.placeIds = self.nearByPlacesArray.map{$0.placeId}
    placesViewModel.reference = self.nearByPlacesArray.map{$0.reference}
    placesViewModel.testTypes = self.nearByPlacesArray.map{$0.types}
    placesViewModel.vicinity = self.nearByPlacesArray.map{$0.vicinity}
      
    placesViewModel.topPlaceVibeAvg { (data) in
         print(data)
    }
Note : **nearByPlacesArray** is main array & i'm to sorting my required array object from here

我真的尝试过解决问题，我已经搜索过这件事但没有得到任何答案。

有人知道这个吗？

【解决方案1】：

要在请求正文中发送复杂的参数，您可以使用 Moya 函数：

requestCompositeData(bodyData: Data, urlParameters: [String: Any])

Moya 对此功能有这样的评论：

带有数据的请求体集，结合url参数

所以这个函数允许我们在请求正文中发送任何内容。

例如这样的事情是一个很好的方法：

import Moya
import SwiftyJSON

// Data task in MoyaProvider

var task: Task {
        switch self {
        case .categoriesAndSubCategories:
            
            let graphQLJson = JSON([
                [
                    "query": "query categories { categories { id, title, description, slug, adsStats, subcategories { id, title, slug } } }"
                ]
            ])
            
            return .requestCompositeData(bodyData: try! graphQLJson.rawData(), urlParameters: [:])
        }
    }
