Поиск транзакций Paypal с использованием Python

Question

У меня есть необходимые данные аутентификации, и я пытаюсь выполнить TransactionSearch. Я получаю сообщение об ошибке: TIMESTAMP = 2013% 2d09% 2d07T19% 3a06% 3a35Z & CorrelationId = b7af040415e92 & ACK = Ошибка & VERSION = 0% 2e000000 & BUILD = 7507921 & L_ERRORCODE0 = 10002 & L_SHORTMESSAGE0 = Аутентификация% 2fAuthorization% 20Failed & = Вы L_LONGMESSAGE0% 20do% 20not% 20have% 20permissions% 20to% 20make% 20this% 20API% 20call & L_SEVERITYCODE0 = Ошибка

Вот мой код:

(timestamp, signature) = signaturegen.getAuthHeader(apiUser=settings.USERNAME, apiPass=settings.PASSWORD, accessTok=res2["token"], secTok=res2["tokenSecret"], httpMethod="POST", scriptURI="https://api-3t.sandbox.paypal.com/nvp")  
#the above operation is used to generate the timestamp and signature 

headers = {"X-PAYPAL-AUTHORIZATION": "timestamp="+<timestamp>+",token="+<token>+",signature="+<signature>, "SUBJECT": settings.<API_USERNAME>} 

data = { 
"METHOD": "TransactionSearch", 
"STARTDATE": "2012-01-01T05:38:48Z", 
} 
req= urllib2.Request("https://api-3t.sandbox.paypal.com/nvp", simplejson.dumps(data), headers) 
res = urllib2.urlopen(req).read()

Мне наконец удалось исправить код, вот полная версия:

import ast 
import signaturegen 
headers = { 
    "X-PAYPAL-SECURITY-USERID": "xxxxxxxxx.xxxx.com", 
    "X-PAYPAL-SECURITY-PASSWORD": "xxxxxxxx", 
    "X-PAYPAL-SECURITY-SIGNATURE": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", 
    "X-PAYPAL-REQUEST-DATA-FORMAT": "JSON", 
    "X-PAYPAL-RESPONSE-DATA-FORMAT": "JSON", 
    "X-PAYPAL-APPLICATION-ID": "APP-80W284485P519543T", #APP ID for sandbox 

} 


    headers = { 
    "X-PAYPAL-SECURITY-USERID": settings.USERNAME,

} 

    data = {"scope":"TRANSACTION_SEARCH", "callback":"http://www.example.com/success.html", "requestEnvelope": {"errorLanguage":"en_US"}} 
    req = urllib2.Request("https://svcs.sandbox.paypal.com/Permissions/RequestPermissions/", simplejson.dumps(data), headers)  
    res = ast.literal_eval(urllib2.urlopen(req).read()) 
    token = res['token'] 
    red_url = "https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_grant-permission&request_token=%s" % token 
    if red_url: 
     return HttpResponseRedirect(red_url) 
    token = "xxxxxxxxxxxxxxxxxx" 
    verification = "xxxxxxxxxxxxxxxxxx" 
    headers2 = {

    url = "https://svcs.sandbox.paypal.com/Permissions/GetAccessToken/" 


    dat2 = {

    (timestamp, signature) = signaturegen.getAuthHeader(apiUser="xxxxxxxxxxxx", apiPass="xxxxxxxxxxxxxxxx", accessTok=res2["token"], secTok=res2["tokenSecret"], httpMethod="POST", scriptURI="https://api-3t.sandbox.paypal.com/nvp")  

    ultimate = {"X-PAYPAL-AUTHORIZATION": "timestamp="+timestamp+",token="+res2["token"]+",signature="+signature, "SUBJECT": settings.USERNAME} 

    da = { 
     "METHOD": "TransactionSearch", 
     "STARTDATE": "2012-01-01T05:38:48Z", 
    } 
    req3 = urllib2.Request("https://api-3t.sandbox.paypal.com/nvp", urllib.urlencode(da), ultimate) 
    res3 = urllib2.urlopen(req3).read()
