Question

一切正常后，我可以毫无问题地从response.body()取回尸体。

可以想到的是，当服务器上发生验证错误（在我的情况下为重复的电子邮件）时，它将错误发送到frontend，并且当我尝试访问错误正文时 response.errorBody（）检索以下信息：

"E/API Activity: onResponse: PostSalao okhttp3.ResponseBody$1@84d856e"

我希望收到类似“错误：电子邮件已使用”之类的信息。。

您可能会在（10:08）的video上看到，他所做的与我在代码中所做的相同，但是他正确地检索了错误（10:17）。

我在做什么错了？

fun postCliente(cliente: Cliente) {
        val TAG = "API Activity"
        val apiInterface: ApiInterface
        apiInterface = ClientApi.getClient().create(ApiInterface::class.java)
        val clientePostCall = apiInterface.postCliente(cliente)
        mProgressBar.visibility = View.VISIBLE

        clientePostCall.enqueue(object: Callback<Cliente> {
            override fun onResponse(call: Call<Cliente>, response: Response<Cliente>) {
                mProgressBar.visibility = View.GONE
                if(response.isSuccessful){
                    try {
                    Toast.makeText(context,"Usuario " + response.body()!!.name + " criado com sucesso.",Toast.LENGTH_SHORT).show()
                        val backHomeIntent = Intent(context, MainActivity::class.java)
                        context.startActivity(backHomeIntent)
                    } catch (e: NullPointerException) {
                        Toast.makeText(context, "Problem is unknown: ", Toast.LENGTH_SHORT).show()
                    }
                }else {
                    try {
                        val errorBody = response.errorBody().toString()


                        Toast.makeText(context, "Dados incorretos", Toast.LENGTH_SHORT).show()
                            Log.e(TAG, "onResponse: " + errorBody )

                    } catch (e: IOException){
                        Toast.makeText(context, "Problem is unknown: ", Toast.LENGTH_SHORT).show()
                    }
                }
            }
            override fun onFailure(call: Call<Cliente>, t: Throwable) {
                mProgressBar.visibility = View.GONE
                Log.e(TAG, "onFailure: " + t.localizedMessage)
            }
        })
    }

您必须使用string（）而不是toString（）来获取正确的错误消息。因此您的代码应如下所示：

fun postCliente(cliente: Cliente) {
    val TAG = "API Activity"
    val apiInterface: ApiInterface
    apiInterface = ClientApi.getClient().create(ApiInterface::class.java)
    val clientePostCall = apiInterface.postCliente(cliente)
    mProgressBar.visibility = View.VISIBLE

    clientePostCall.enqueue(object: Callback<Cliente> {
        override fun onResponse(call: Call<Cliente>, response: Response<Cliente>) {
            mProgressBar.visibility = View.GONE
            if(response.isSuccessful){
                try {
                Toast.makeText(context,"Usuario " + response.body()!!.name + " criado com sucesso.",Toast.LENGTH_SHORT).show()
                    val backHomeIntent = Intent(context, MainActivity::class.java)
                    context.startActivity(backHomeIntent)
                } catch (e: NullPointerException) {
                    Toast.makeText(context, "Problem is unknown: ", Toast.LENGTH_SHORT).show()
                }
            }else {
                try {
                    val errorBody = response.errorBody().string()


                    Toast.makeText(context, "Dados incorretos", Toast.LENGTH_SHORT).show()
                        Log.e(TAG, "onResponse: " + errorBody )

                } catch (e: IOException){
                    Toast.makeText(context, "Problem is unknown: ", Toast.LENGTH_SHORT).show()
                }
            }
        }
        override fun onFailure(call: Call<Cliente>, t: Throwable) {
            mProgressBar.visibility = View.GONE
            Log.e(TAG, "onFailure: " + t.localizedMessage)
        }
    })
}

如何在改造错误处理程序上检索从服务器发送的errorBody？
