Oauth2錯誤與MapMyFitness API

Question

我想使用MapMyFitness API（www.mapmyapi.com）與Ruby on Rails 3.2和oauth2寶石。首先，我的應用程序在「get_auth_url」中生成auth_url。瀏覽器然後導航到它，一旦認證，回調就會返回到「mapmyfitness_callback」。 「mapmyfitness_callback」也獲得「鍛鍊」列表，並在瀏覽器中顯示。

問題出在用戶選擇要下載的鍛鍊時。要檢索選定的鍛鍊，我稱之爲「get_workout」。但是，我很難獲取請求的相應標記。

下面崩潰的行：

workout_data = access_token.get('/v7.0/workout/' + workout_id, :params => { 'field_set' => 'time_series' }, :headers => {'Api-Key' => ENV['MMF_API_KEY'], 'Authorization' => auth_token}).body 

與：OAuth2用戶::錯誤（： { 「oauth1_error」： 「格式錯誤的授權頭」， 「oauth1_error_code」： 「您好！OAuth1：UNKNOWN」}）： 應用/controllers/telemetry_controller.rb:60:in`get_workout」

整個控制器的代碼：

require 'oauth2' 

class TelemetryController < ApplicationController 

    def get_auth_url 
    auth_url = mmf_client.auth_code.authorize_url(:redirect_uri => 'http://localhost:3000/telemetry/mapmyfitness_callback') 

    respond_to do |format| 
     format.json{ render :json => {:auth_url => auth_url}.to_json } 
    end 
    end 

    def mapmyfitness_callback 

    # Get user 
    @code = params[:code] 
    token = mmf_client.auth_code.get_token(@code, :redirect_uri => 'http://localhost:3000/telemetry/mapmyfitness_callback', :headers => {'Api-Key' => ENV['MMF_API_KEY']}) 
    mmf_user = JSON.parse(token.get('/v7.0/user/self', :headers => {'Api-Key' => ENV['MMF_API_KEY'], 'Authorization' => @code}).body) 
    mmf_user_id = mmf_user['id'] 

    @auth_token = token.token 

    # Get workouts 
    mmf_workouts = JSON.parse(token.get('/v7.0/workout', :params => { 'user' => mmf_user_id }, :headers => {'Api-Key' => ENV['MMF_API_KEY'], 'Authorization' => @code}).body) 

    @workout_list = Array.new 
    mmf_workouts['_embedded']['workouts'].each do |workout| 
     workout_data = {:name => workout['name'], 
         :id => workout['_links']['self'][0]['id']} 
     @workout_list.push(workout_data) 
    end   

    render :layout => false 

    end 

    def get_workout 

    code = params[:code] 
    auth_token = params[:auth_token] 

    access_token = OAuth2::AccessToken.new(mmf_client, auth_token, { 
     :mode => :query, 
     :param_name => "oauth2_access_token", 
    })  

    puts access_token.to_yaml 

    # Get workout 
    workout_id = params[:workout_id] 
    workout_data = access_token.get('/v7.0/workout/' + workout_id, :params => { 'field_set' => 'time_series' }, :headers => {'Api-Key' => ENV['MMF_API_KEY'], 'Authorization' => auth_token}).body 

    respond_to do |format| 
     format.json{ render :json => {:mmf_workout_data => workout_data}.to_json } 
    end 

    end 

    private 

    def mmf_client 

    client = OAuth2::Client.new(
     ENV['MMF_API_KEY'], 
     ENV['MMF_SECRET_KEY'], 
     :authorize_url => "https://www.mapmyfitness.com/v7.0/oauth2/authorize/", 
     :token_url => "https://oauth2-api.mapmyapi.com/v7.0/oauth2/access_token/", 
     :site => "https://oauth2-api.mapmyapi.com" 
    ) 

    end 

end 

Answer 1

我計算出來。 get_workout需要如下所示：

def get_workout 

    auth_token = params[:auth_token] 

    token = OAuth2::AccessToken.new(mmf_client, auth_token) 

    # Get workout 
    workout_id = params[:workout_id] 
    workout_data = token.get('/v7.0/workout/' + workout_id, :params => { 'field_set' => 'time_series' }, :headers => {'Api-Key' => ENV['MMF_API_KEY'], 'Authorization' => auth_token}).body 

    respond_to do |format| 
     format.json{ render :json => {:mmf_workout_data => workout_data}.to_json } 
    end 

    end 

Answer 2

您調用AccessToken.new的問題是「param_name」。

從文檔（ http://www.rubydoc.info/github/intridea/oauth2/ebe4be038ec14b349682/OAuth2/AccessToken）

：PARAM_NAME（字符串） - 缺省： 'bearer_token' - 參數名稱以用於在訪問令牌值的傳輸：體或：查詢傳輸模式

默認值是「bearer_token」，因爲它應該是，但在這裏，您將其更改爲「oauth2_access_token」。
