我已成功地遵循了rauth OAuth1示例來獲取我的訪問令牌,因此檢索fatsecret API中的數據。我將我的access_token和access_token_secret存儲在擱置數據庫中。我的問題是,當我嘗試使用存儲的令牌以稍後檢索更多數據時,我收到「無效簽名」錯誤。使用rauth從fatsecret API發出的無效簽名
這是我原來的劇本獲得令牌和檢索exercise_entries.get
方法:
from rauth.service import OAuth1Service
import shelve
api_url = 'http://platform.fatsecret.com/rest/server.api'
shelf = shelve.open('token_shelf.db')
fatsecret = OAuth1Service(
consumer_key = 'xxxxxxxxxxxxx',
consumer_secret = 'xxxxxxxxxxxxx',
name = 'fatsecret',
request_token_url = 'http://www.fatsecret.com/oauth/request_token',
access_token_url = 'http://www.fatsecret.com/oauth/access_token',
authorize_url = 'http://www.fatsecret.com/oauth/authorize')
request_token, request_token_secret = fatsecret.get_request_token(
method = 'GET',
params = {'oauth_callback':'oob'})
authorize_url = fatsecret.get_authorize_url(request_token)
print 'Visit this URL in your browser: ' + authorize_url
pin = raw_input('Enter PIN from browser: ')
shelf['fatsecret_request_token'] = request_token
shelf['fatsecret_request_token_secret'] = request_token_secret
shelf['fatsecret_pin'] = pin
session = fatsecret.get_auth_session(
request_token,
request_token_secret,
params={'oauth_verifier': pin}
)
shelf['fatsecret_access_token'] = session.access_token
shelf['fatsecret_access_token_secret'] = session.access_token_secret
my_params = {'method': 'exercise_entries.get', 'format': 'json'}
r = session.get(api_url, params=my_params)
print r.json()
print r.content
shelf.close()
然後我嘗試從貨架恢復我的access_token和access_token_secret並打開一個新的會話,但我告訴我有一個簽名無效。
from rauth.service import OAuth1Service
import shelve
api_url = 'http://platform.fatsecret.com/rest/server.api'
shelf = shelve.open('token_shelf.db')
fs_access_token = shelf['fatsecret_access_token']
fs_access_token_secret = shelf['fatsecret_access_token']
fatsecret = OAuth1Service(
consumer_key = 'xxxxxxxxxxxxx',
consumer_secret = 'xxxxxxxxxxxxx',
name = 'fatsecret',
request_token_url = 'http://www.fatsecret.com/oauth/request_token',
access_token_url = 'http://www.fatsecret.com/oauth/access_token',
authorize_url = 'http://www.fatsecret.com/oauth/authorize')
session = fatsecret.get_session((fs_access_token,fs_access_token_secret))
my_params = {'method': 'exercise_entries.get', 'format': 'json'}
r = session.get(api_url,params=my_params)
print r.content
print r.url
shelf.close()
這將返回r.content
爲:
{ "error": {"code": 8, "message": "Invalid signature: oauth_signature 'ccZpSYAPSn+umkTxcAVH7EChVvw='" }}
和r.url
是:
http://platform.fatsecret.com/rest/server.api?oauth_nonce=604416f368159818e3ad8252a0da323be16319a3&format=json&oauth_consumer_key=xxxxxxxxxxxxx&oauth_timestamp=1390015877&oauth_signature_method=HMAC-SHA1&oauth_version=1.0&oauth_token=xxxxxxxxxxxxx&oauth_signature=l4Ricqpbbwl%2BHPS2ItLLnvXQo%2FA%3D&method=exercise_entries.get
那映入我眼簾的是,r.url參數似乎沒有被lexigraphically唯一排序,但我不知道這是否準確地反映了發送給fatsecret的內容,無論如何,它在第一個腳本中運行良好。
我試過類似的東西using OAuth1Session而不是OAuth1Service
,但我收到完全相同的結果。
我很感激任何幫助,讓這項工作。
