通过JavaScript未经授权访问Google Calendar API [英] Accessing Google Calendar API without authorization via JavaScript

问题描述

我尝试访问包含全国假日的公共日历（来自Google日历）：

  calendarId：'pt_br .brazilian＃holiday @ group.v.calendar.google.com'
  

由于日历是公开的，我认为我只能使用API​​ Key访问它：

 函数OnLoadCallback（）{
 var config = {
 client_id：'32j4lk32j5kj342l5h.googleuser.com'，//假客户ID 
范围：'https://www.googleapis.com/auth/calendar.readonly'
}; 
 gapi.client.setApiKey（'fId345AM20HXXXXXXXXXXXXXXXXgT3f9kyp2REfkaw2'）; //假api键
 gapi.client.load（'calendar'，'v3'，function（）{
 var today = new Date（），
 request; 
 
 request = gapi.client.calendar.calendarList.get（{
 calendarId：'pt_br.brazilian#[e-mail]'，
 timeMin：（new Date（ today.getFullYear（），today.getMonth（），today.getDay（），0，0，0，0））。toISOString（），
 timeMax：（new Date（today.getFullYear（），today。 getMonth（），today.getDay（），23,59,59,999））。toISOString（），
 fields：'items（creator（displayName，email），end，endTimeUnspecified，start，summary）'
}）; 
 
 request.execute（function（response）{
 window.alert（'items of length：'+ response.items.length）; 
} ）; 
 
}）; 
} 
  

然而，我一直得到以下回应，这是401（未授权）错误：

  {
错误：{
错误：[
 { 
domain：global，
reason：required，
message：需要登录，
locationType：header，
location：Authorization
} 
]，
code：401，
message：需要登录
} 
 
  

有人可以澄清我试图做的事是否可以实现吗？ >
最后如果可能的话 - 我必须改变什么来引用当前的代码？

解决方案

我能够用jQuery做同样的事情。

  var mykey ='your_api_key'; //通常类似于Gtg-rtZdsreUr_fLfhgPfgff 
 var calendarid ='you_calendar_id'; //看起来有点像[e-mail] 
 $ b $ .ajax（{
类型：'GET'，
 url：encodeURI（'https：/ /www.googleapis.com/calendar/v3/calendars/'+ calendarid +'/ events？key ='+ mykey），
 dataType：'json'，
 success：function（response）{
 //对每个
做任何你想做的事
 error：function（response）{
 //告诉发生错误
} 
}） ; 
  

然而，您需要确保您已完成以下操作： - $ / b

---

1）在 https ：//code.google.com/apis/console

2）生成一个简单的API访问密钥

3）确保Calendar API在服务下激活。 p>

I'm trying to access a public calendar (from Google Calendar) that contains national holidays:

calendarId: 'pt_br.brazilian#[e-mail]'

As the calendar is public, I thought I would be able to access it using only the API Key:

function OnLoadCallback() {
    var config = {
        client_id: '32j4lk32j5kj342l5h.googleuser.com', //fake client id
        scope: 'https://www.googleapis.com/auth/calendar.readonly'
    };
    gapi.client.setApiKey('fId345AM20HXXXXXXXXXXXXXXXXgT3f9kyp2REfkaw2'); //fake api key
    gapi.client.load('calendar', 'v3', function() {
        var today = new Date(),
            request;

        request = gapi.client.calendar.calendarList.get({
            calendarId: 'pt_br.brazilian#[e-mail]',
            timeMin: (new Date(today.getFullYear(), today.getMonth(), today.getDay(), 0, 0, 0, 0)).toISOString(),
            timeMax: (new Date(today.getFullYear(), today.getMonth(), today.getDay(), 23, 59, 59, 999)).toISOString(),
            fields: 'items(creator(displayName,email),end,endTimeUnspecified,start,summary)'
        });

        request.execute(function(response) {
            window.alert('length of items: ' + response.items.length);
        });

    });
}

However, I keep getting the following response, which is a 401 (unauthorized) error:

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "required",
    "message": "Login Required",
    "locationType": "header",
    "location": "Authorization"
   }
  ],
  "code": 401,
  "message": "Login Required"
 }
}

Can someone clarify whether what I'm trying to do is achievable or not?
And finally if it is possible - what do I have to change referring to my current code?

解决方案

I was able to do the same thing using jQuery.

var mykey = 'your_api_key'; // typically like Gtg-rtZdsreUr_fLfhgPfgff
var calendarid = 'you_calendar_id'; // will look somewhat like [e-mail]

$.ajax({
    type: 'GET',
    url: encodeURI('https://www.googleapis.com/calendar/v3/calendars/' + calendarid+ '/events?key=' + mykey),
    dataType: 'json',
    success: function (response) {
        //do whatever you want with each
    },
    error: function (response) {
        //tell that an error has occurred
    }
});

However you need to be sure you have done the following:-

---

1) Register a project at https://code.google.com/apis/console
2) Generate a Simple API Access key
3) Ensure Calendar API is activated under services.
