从服务器API错误输出自定义Rx Java中的onError消息

如何解决从服务器API错误输出自定义Rx Java中的onError消息

我想打印API消息发送的错误，例如其中有很多示例：电子邮件已经存在，用户名已经退出等。 但这仅打印HTTP 400错误请求

fun doSignUp(
        firstName: String,lastName: String,email: String,password: String,deviceid: String
    ) {

        ApiHelper().userSignup(
            firstName,lastName,email,password,"Android",sTradd)
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(object : Observer<UserResponse>{
                override fun onComplete() {
                    Log.d("kb","onComplete Call")
                }

                override fun onSubscribe(d: disposable) {
                    Log.d("kb","onSubscribe")
                }

                override fun onNext(t: UserResponse) {
                    Toast.makeText(applicationContext,"Please Upload Profile Pic...",Toast.LENGTH_SHORT).show()
                    val intent = Intent(applicationContext,SignupStep3Activity::class.java)
                    mPref.setAccesstoken(t.data.accesstoken)
                    startActivity(intent)
                }


                override fun onError(e: Throwable) {
                   Toast.makeText(applicationContext,e.localizedMessage,Toast.LENGTH_LONG).show()
                }
            })
    }

这是我的api在错误响应中显示的内容

    "message": "Email Already Exists","code": 400,"errors": {
        "error_id": "15","error_text": "Email Already Exists"
    },"data": []
}

我是Kotlin的新手，在这里，请原谅我的任何错误

解决方法

在您的onNext()中，您需要这样的内容：

when (UserResponse.code()) {
                        200 -> {//Send appropriate message with intent here}
                        400 -> {//Send appropriate message with intent here}
                        401 -> {//Send appropriate message with intent here}
                        712 -> {//Send appropriate message with intent here}
}
