Rails 4：创建谷歌日历事件

Question

我正在尝试插入 Google 日历活动，如图所示 here。如果我发送带有硬编码值的请求，例如示例，它可以正常工作：

event = {'summary' => 'Summary',
         'location' => 'Location',
         'start' => { 'dateTime' => '2011-06-03T10:00:00.000-07:00' },
         'end' => { 'dateTime' => '2011-06-03T10:25:00.000-07:00' }}

但如果我尝试发送变量，它会静默失败：

event = {'summary' => "#{params[:summary]}",
         'location' => "#{params[:location]}",
         'start' => { 'dateTime' => "#{params[:start_time]}" },
         'end' => { 'dateTime' => "#{params[:start_time]}" }}

如果我这样格式化也会失败：

event = "{
          \"summary\": \"#{params[:summary]}\",
          \"location\": \"#{params[:location]}\",
          \"start\": { \"dateTime\": \"#{params[:start_time]}\" },
          \"end\": { \"dateTime\": \"#{params[:end_time]}\" }
        }"

我可以让它成功发布start_time 和end_time 格式如下：Date.today.strftime("%Y-%m-%dT%l:%M:%S.000-07:00")，但这不太理想，因为我相信start_time 和end_time 参数已经是@987654330 @对象。

表单正在传递参数，因为我在 Rails 控制台中得到了这个（为简洁起见，省略了authenticity_token）：

Processing by EventsController#create as HTML
  Parameters: {"utf8"=>"✓",
               "authenticity_token"=>"...",

                         "start_time(1i)"=>"2015",
                         "start_time(2i)"=>"4",
                         "start_time(3i)"=>"15",
                         "start_time(4i)"=>"14",
                         "start_time(5i)"=>"54",
                         "end_time(1i)"=>"2015",
                         "end_time(2i)"=>"4",
                         "end_time(3i)"=>"15",
                         "end_time(4i)"=>"14",
                         "end_time(5i)"=>"55",
                         "location"=>"Location"},
               "commit"=>"Create Event"}

以下是相关代码：

client = Google::APIClient.new({:application_name => "PlannerApp",
                                :application_version => "1.0"})
client.authorization.access_token = t.fresh_token
service = client.discovered_api('calendar', 'v3')
client.execute(:api_method => service.events.insert,
               :parameters => {'calendarId' => 'primary'},
               :body => JSON.dump(event),
               :headers => {'Content-Type' => 'application/json'})

这是我从 Google 获得的信息（Authorization 为简洁起见省略）：

Google::APIClient::Request Sending API request get https://www.googleapis.com/discovery/v1/apis/calendar/v3/rest {
  "User-Agent"=>"PlannerApp/1.0 google-api-ruby-client/0.8.5 Mac OS X/10.10.2\n (gzip)",

  "Content-Type"=>""}

  "Cache-Control"=>"no-store"}

我应该如何格式化这些 event 哈希值以获得成功的 POST？

解决方案：

event = {'summary' => "#{params[:event][:summary]}",
         'location' => "#{params[:event][:location]}",
         'start' => { 'dateTime' => Time.new(params['event']['start_time(1i)'],
                                             params['event']['start_time(2i)'],
                                             params['event']['start_time(3i)'],
                                             params['event']['start_time(4i)'],
                                             params['event']['start_time(5i)'])
                                        .to_datetime.rfc3339,
                      'timeZone' => "America/Denver" },
         'end' => { 'dateTime' => Time.new(params['event']['end_time(1i)'],
                                           params['event']['end_time(2i)'],
                                           params['event']['end_time(3i)'],
                                           params['event']['end_time(4i)'],
                                           params['event']['end_time(5i)'])
                                      .to_datetime.rfc3339,
                    'timeZone' => "America/Denver" }}

Answer 1

您的参数是嵌套的。所以它会是：

event = {'summary' => "#{params[:event][:summary]}",
     'location' => "#{params[:event][:location]}",
     'start' => { 'dateTime' => "#{params[:event][:start_time]}" },
     'end' => { 'dateTime' => "#{params[:event][:start_time]}" }}
