ios - Alamofire .post API 错误 : Code=3840 "Invalid value around character 1

Question

将 Alamofire 用于 .post api，api 在 postman 中提供数据但不在我的代码中。在代码下方发布，请指导我在这里做错了什么:

// API calling method:

parameters = [
        "Address" : "" as AnyObject,
        "Name" :  "" as AnyObject,
        "ServiceID" : "" as AnyObject,
        "Rating" :  "" as AnyObject,
        "Price" :  "" as AnyObject
    ]

    let headers: Dictionary = [
        "" : ""
    ]

    print(parameters)

    ApiServices.requestPOSTURL(strURL, params: parameters, headers: headers, success:{

        (JSONResponse) -> Void in

        CommonMethodsClass.hideHUD(targetView: self.view)

        print(JSONResponse["message"])

        let strMsg = JSONResponse["message"].stringValue


        if (JSONResponse["status"].intValue == 1)
        {  

        }
        else
        {
            CommonMethodsClass.showAlertMessage(vc: self, titleStr: "Error!", messageStr: strMsg)
        }

    }) {
        (error) -> Void in
        print(error)

        CommonMethodsClass.hideHUD(targetView: self.view)
    }


// Api request method:
class func requestPOSTURL(_ strURL : String, params : [String : AnyObject]?, headers : [String : String]?, success:@escaping (JSON) -> Void, failure:@escaping (Error) -> Void){

    Alamofire.request(strURL, method: .post, parameters: params, encoding: JSONEncoding.default).responseJSON { (responseObject) -> Void in

        print(responseObject)

        if responseObject.result.isSuccess {
            let resJson = JSON(responseObject.result.value as Any)
            success(resJson)
        }
        if responseObject.result.isFailure {
            let error : Error = responseObject.result.error!
            failure(error)
        }
    }
}

Error: FAILURE: responseSerializationFailed(Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed(Error Domain=NSCocoaErrorDomain Code=3840 "Invalid value around character 1." UserInfo={NSDebugDescription=Invalid value around character 1.}))

更新:对解析的响应，可能还需要更改。

{
    "status": true,
    "message": "",
    "data": [
        {
            "SalonID": "1",

            "Latitude": "",
            "Longitude": "",

            "SalonImage": "",
            "TimeIntervalminutes": 30,
            "AverageRating": 5,
            "IsActive": 1
        }
    ]
}

将 responseJSON 替换为 responseString。

您需要将字符串转换为值。你能更新问题中的字符串吗？

您可以使用此函数将响应字符串转换为 JSON:

func convertToDictionary(text: String) -> [String: Any]? {
    if let data = text.data(using: .utf8) {
        do {
            return try JSONSerialization.jsonObject(with: data, options: []) as? [String: Any]
        } catch {
            print(error.localizedDescription)
        }
    }
    return nil
}

字符串:let str = "{\"name\":\"James\"}"

用法:let dict = convertToDictionary(text: str)
