改装请求后错误-java.lang.IllegalStateException:应为BEGIN_对象，但在第1行第1列路径处为字符串$

我正在尝试使用改装、MVVM、协同程序和刀柄发出Post请求

在发送post请求后，我得到了这个错误

java.lang.IllegalStateException:应为BEGIN\u对象，但在第1行第1列路径$处为字符串。

（我已经搜索过了，但没有一个有用）

新用户

data class NewUser (

@SerializedName("birthday") val birthday: String?,
@SerializedName("birth_year") val birthYear: String?,

注册REPO

suspend fun saveUserWithEmail(newUser: NewUser) = safeApiCall { 
apiDataSource.createNewUserEmail(newUser) }

注册服务模型

//SaveUserDetails

private val _saveDetailsEmail = MutableLiveData<Resource<JsonResponse>>()

fun doRegisterUserEmail(newUser: NewUser) = viewModelScope.launch {
    try {
        _saveDetailsEmail.value = registerRepo.saveUserWithEmail(newUser)
    }
    catch (exception: Exception){

    }
}

寄存器片段

val userDetails = NewUser(usernameString, passwordPassed, emailPassed, birthdayPassed, birthYearPassed, fullnameString, genderString)
    registerViewModel.doRegisterUserEmail(userDetails)


    registerViewModel.saveDetailsEmail.observe(viewLifecycleOwner, Observer {
        when(it.status){
            Resource.Status.SUCCESS -> {
                if(it.data?.success == "0"){
                    //Display error
                    Toast.makeText(requireContext(), it.data.message + "Registration", Toast.LENGTH_LONG ).show()
                }
                else if(it.data?.success == "1"){
                    //go to home activity
                    Toast.makeText(requireContext(), it.data.message + "Registrationx", Toast.LENGTH_LONG ).show()
                    val action  = DetailsFragmentDirections.actionDetailsFragmentToHomeActivity()
                    navController.navigate(action)
                }
            }
            Resource.Status.LOADING -> {
                //Show loading
            }
            Resource.Status.ERROR -> {
                Toast.makeText(requireContext(), it.toString(), Toast.LENGTH_LONG).show()
            }
        }
    })

}

这是与邮递员测试后的反应。它起作用了

{"success":"1","message":"User details saved"} 

更新资源类

data class Resource<out T>(val status: Status, val data: T?, val message: String?) {

enum class Status {
    SUCCESS,
    ERROR,
    LOADING
}


companion object {
    fun <T> success(data: T): Resource<T> {
        return Resource(Status.SUCCESS, data, null)
    }

    fun <T> error(message: String, data: T? = null): Resource<T> {
        return Resource(Status.ERROR, data, message)
    }

    fun <T> loading(data: T? = null): Resource<T> {
        return Resource(Status.LOADING, data, null)
    }
}

}

我必须解码发送到服务器的JSON，特别是当这里的内容类型是应用程序/JSON

$data = file_get_contents('php://input');
$json_data = json_decode($data , true);
//I added these above

if ($_SERVER['REQUEST_METHOD']=='POST'){

 $username = $json_data["username"];
 $password = $json_data["password"];
 $email = $json_data["email"];

}

你能发布整个日志吗？实际上，这是网络呼叫响应未成功时引发的唯一异常错误。你能解释一下

资源
？资源是一个帮助获取网络呼叫状态的类-（成功、加载或错误）。因此，JsonResponse由一个资源包装，用于正确的错误处理和了解状态。检查更新后的问题。@AdityaKurkure在检查okHttp后，我得到了android中JSON传递的所有值的不精确索引。完整性约束冲突：1048列“用户名”在。。。同时，JSON在LogCat中显示得很好，但行内容类型为text/htm——显示了未定义变量的错误
