错误（错误域= NSCocoaErrorDomain代码= 3840“字符0周围的值无效。”UserInfo = {NSDebugDescription =字符0周围的值无效}

Question

我收到此错误为JSON result.error。虽然我的JSON是有效的，但请在线查看JSON vaildator。

这是我的JSON请求代码。

Alamofire.request(.POST, url, parameters: parameters, encoding:.JSON)
                .responseJSON { (request, response, result) in
                    hud.hide(true)
                    // Set flag to disale poor internet connection alert
                    weakInternet = false
                    print(result.error)
                    if (result.value != nil) {
                        print("API Response: \(result.value!)")
                        // Pass the response JSON to the completion block
                        completion(json: result.value!)
                    } else {
                        // Response JSON is NULL
                    }
            }

当我使用特定的请求参数点击相同的服务时，我得到了这个响应。

有谁知道我的问题是什么？

Answer 1

我的网络服务存在问题。他们以“text / HTML”格式而不是HTML格式给我回复。当我在调试器上打印我的响应时，我得到了：

"Content-Type" = "text/html; charset=UTF-8";

现在，我更新了我的网络服务，一切都像魅力一样。

Answer 2

我上次得到相同的错误，因为会有问题是Web服务返回我在数组中的响应，我试图将其转换为字典并提取其值。

检查您的Web服务响应。

Answer 3

Swift 5，Swift 4

var headers = HTTPHeaders()
    headers = [
        "Content-Type" :"text/html; charset=UTF-8",
        //"Content-Type": "application/json",
        //"Content-Type": "application/x-www-form-urlencoded",
        //"Accept": "application/json",
        "Accept": "multipart/form-data"
    ]
