python - 如何使用 Python 对 Paypal API 进行 TransactionSearch 调用

Question

我有必要的身份验证详细信息，并且正在尝试执行 TransactionSearch。我不断收到错误： ACK=Failure&L_ERRORCODE0=81002&L_SHORTMESSAGE0=Unspecified%20Method&L_LONGMESSAGE0=Method%20Specified%20is%20not%20Supported&L_SEVERITYCODE0=Error

这是我的代码：

(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()

我在做什么我做错了。

Answer 1

使用urllib.urlencode而不是simplejson.dumps用于商家 nvp API。

req= urllib2.Request("https://api-3t.sandbox.paypal.com/nvp", urllib.urlencode(data), headers)
