【问题描述】：

美好的一天，我目前正在努力将数据发布到我的后端我是快速开发的新手，请帮助

API 要求我发送以下结构：

  "oid": "string",
  "businessKey": "string",
  "refNumber": "string",
  "name": "string",
  "cost": "string",
  "clientOid": "string",
  "vehicleOid": "string",
  "driverOid": "string",
  "from": 
    "oid": "string",
    "businessKey": "string",
    "coordinates": [
      "string"
    ],
    "address": "string"
  ,
  "to": 
    "oid": "string",
    "businessKey": "string",
    "coordinates": [
      "string"
    ],
    "address": "string"
  ,
  "when": "2018-04-09T10:03:01.156Z",
  "atp": "2018-04-09T10:03:01.156Z",
  "eta": "2018-04-09T10:03:01.156Z",
  "ata": "2018-04-09T10:03:01.156Z",
  "droplets": [
    
      "oid": "string",
      "businessKey": "string",
      "itemOid": "string",
      "description": "string",
      "notes": "string"
    
  ],
  "serviceRating": 0,
  "notes": "string"

我的代码是这样的：

func createDrop(oid: String, token: String)

    let url = getCar.url
    let token = "Bearer " + token
    var request = URLRequest(url: URL(string: "\(url)drops")!)
    request.httpMethod = "POST"
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")
    request.setValue( token, forHTTPHeaderField: "Authorization")

    var parameters: Dictionary<String, Any> = [
        "name": "Thami",
        "notes": "New",
        "cost": "totalPrice",
        "clientOid": "clientOi",
        "vehicleOid": "vehicleOi",
        "driverOid": "driverO",
        "when": "dropTime",
        "atp": "dropTime",
        "eta": "dropTime",
        "ata": "dropTime",
        "from":[
            "coordinates": [
            "-26.002483",
            "28.099503"
            ],
            "address": "his.distanceInfo.getPickUp()",
        ],
        "to":[
            "coordinates": [
            "-26.002483",
            "28.099503"
            ],
            "address": "this.distanceInfo.getDestination()",
        ],
        "droplets":[
            "itemOid": "575ae6bd30bc5d5017477143",
            "notes": "new"
        ]

    ]

    do 
        request.httpBody  = try JSONSerialization.data(withJSONObject: parameters, options: [])
        print("serilizing json")
     catch 
        print("JSON serialization failed:  \(error)")
    
     print(parameters)
    Alamofire.request(request).responseJSON (response) in
         debugPrint(response)
        if response.response?.statusCode == 200 
            print ("pass")
            let dropJSON : JSON = JSON(response.result.value!)
            print(dropJSON)
        else
            print ("fail gfgdfds")
            let dErrorJSON : JSON = JSON(response.result.error!)
            print(dErrorJSON)
        

    

这是我得到的错误：

[结果]: FAILURE: responseSerializationFailed(Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed(Error Domain=NSCocoaErrorDomain Code=3840 "字符 0 附近的值无效。" UserInfo=NSDebugDescription=字符 0 附近的值无效))

如何格式化我的对象来执行这篇文章

【参考方案1】：

尝试对请求中的参数进行编码，例如

Alamofire.request("https://httpbin.org/post", method: .post, parameters: parameters, encoding: JSONEncoding.default)

查看文档以获取更多编码信息 https://github.com/Alamofire/Alamofire/blob/master/Documentation/Usage.md#json-encoding
