javascript - 获取对数组 ipinfo.io 的 Json 响应

Question

您好，我在获取用户 IP 和位置方面遇到了问题。 JSON 响应有效，但我在将其放入我的问题数组时遇到问题。每当弹出问题时

"Your current location?"

它变成空白。相反，我希望它打印:

"Your located: IP address from ipinfo.io and Location. Example ip: 123.123.132 Location: USA"

或任何其他方式获取用户 IP 和位置并将其显示为对话框您位于:p:123.123.132 位置:美国。

let questions = [
  {text:'What is your name?', audio:'music/openmind.ogg', response : input => 'Hello ' + input + '!' },
  {text:'How old are you?', response : input => 'That means you were born in ' + (2017 - input) + '.'},
  {text:'Where are you from?', audio:'music/beone.ogg', response: input => 'You are from ' + (input) + '.'},
  {text: 'Do you eat healthy?', audio: 'music/becoming.ogg', response: input => 'Acording to my data you are eating ' + (input) + ' and that is healthy!'},
  {text: 'What is your time?', audio: 'music/becoming.ogg', response: input => 'Where I am located' + (new Date().toLocaleTimeString()) + 'that is the day!'},
  {text: 'What language do you speak', audio: 'music/becoming.ogg', response: input => 'Acording to me you speak: ' + language() + '!'},
  {text: 'Your current location?', audio: 'music/becoming.ogg', response: input => 'You are located:' + (response) + '!'},


 ];

let output = $('#output'),
    input = $("#input"),
    curQuestion;

function ask() {
  let qi = Math.floor(Math.random() *  questions.length); //depending on your needs, a check could be added if it's been asked directly before or only recycle questions when all are asked
  curQuestion = questions[qi];
  setOutput(curQuestion.text);
  input.val('');
}

ask(); //first call

function respond(){
  let q = curQuestion;
  if(q.audio)
    new Audio(q.audio).play();
  setOutput(q.response(input.val()));
  setTimeout(ask, 5000);
}

function setOutput(txt){
  output.html($('<h1>').text(txt));
}


$(document).keypress(function(e) {
  if (e.which == 13) {
    respond();
    return false;
  }
});

function language () {
  var userLang = navigator.language || navigator.userLanguage;
  return userLang
}

$.get("http://ipinfo.io", function (response) {
    $("#ip").html("IP: " + response.ip);
    $("#address").html("Location: " + response.city + ", " + response.region);
    $("#details").html(JSON.stringify(response, null, 4));
}, "jsonp");

Answer 1

您在questions 范围内没有response 所以这样:

let questions = [
  ...,
  {
    text: 'Your current location?', 
    audio: 'music/becoming.ogg', 
    response: input => 'You are located:' + (response) + '!'
  }
 ];

将不起作用。

您需要以某种方式传递来自 ipinfo.io 的响应。

当你打电话时

$.get("http://ipinfo.io", function (response) {
  $("#ip").html("IP: " + response.ip);
  $("#address").html("Location: " + response.city + ", " + response.region);
  $("#details").html(JSON.stringify(response, null, 4));
}, "jsonp");

您似乎将响应存储在几个 DOM 元素中，因此您可以从那里检索它或只显示这些元素....(我在您的 HTML 中没有看到)

或者将其存储在与questions相同作用域的变量中

let questions = ...    
let ipinfoResponse;
...

$.get("http://ipinfo.io", function (response) {
  ipinfoResponse = response;
}, "jsonp");

并且在 response: input => 'You are located:' + (ipinfoResponse) + '!' 中使用 ipinfoResponse 而不是 response >

但请注意，这种方式 ipinfoResponse 在您收到响应之前将是未定义的。您可能应该在需要时调用 ipinfo，并在您有数据时做出响应。
