swift - swift4：最后的垃圾。错误

问题描述

使用Alamofire,swiftyJSON和swift4，我得到了这个错误

错误：responseSerializationFailed（Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed（错误域 = NSCocoaErrorDomain 代码 = 3840 “垃圾结束。” UserInfo = {NSDebugDescription = 垃圾结束。}））

使用调用此 API 时

class func getLatestProducts( completion: @escaping (_ error: Error?, _ success: Bool,_ value: ErrorModel) -> Void) {

    let url = URLs.latestProducts

    print("url::: ", url)

    Alamofire.request(url, method: .get, encoding: URLEncoding.default, headers: nil)
        .responseJSON { reponse in
            switch reponse.result {
            case .failure(let error):
                print("error: ", error)
                completion(error, false, ErrorModel())
            case .success(let value):
                let json = JSON(value)
                print(json)
                completion(nil, true, ErrorModel())
            }
    }
}

在不同站点进行测试时，响应采用快速格式，这就是响应

这里有什么问题 ？

解决方案

1-添加此而不是 nil 标头

let headers : HTTPHeaders = ["Content-Type":"application/json"]

2-添加这个

.validate().responseJSON
