[英]SP-API "Invalid Input" error for all report requests
当我向“库存”或“销售”端点发出请求时,我得到了成功的响应。 这证实了我的签名和 IAM 是正确的。 我正在手动签署请求,因为我不确定如何使用 boto3 创建签名。
我不知道为什么,但是在发出 POST 请求时,响应将 state The Canonical String for this request should have been...
并提供下面的payload_hash
。 我正在复制/粘贴提供的字符串。 一旦我这样做了,我就会得到InvalidInput
响应。 但是,当使用 GET 请求时,我可以使用payload_hash = hashlib.sha256(('').encode('utf-8')).hexdigest()
如下所示,它工作正常。
这与GET_SALES_AND_TRAFFIC_REPORT
和其他报告的响应相同。
创建规范字符串:
t = datetime.datetime.utcnow()
amzdate = t.strftime('%Y%m%dT%H%M%SZ')
datestamp = t.strftime('%Y%m%d')
canonical_querystring = '/reports/2021-06-30/reports'
signed_headers = 'host;user-agent;x-amz-access-token;x-amz-date'
payload_hash = 'deda182f2e780e6c5e6abb9b19a087a8db6c620c39e784bf4a3384e76d742278'
# payload_hash = hashlib.sha256(('').encode('utf-8')).hexdigest()
canonical_request = method + '\n' + canonical_querystring + '\n' + '\n' + 'host:' + host + '\n' + 'user-agent:python-requests/2.27.1' + '\n' + 'x-amz-access-token:' + access + '\n' + 'x-amz-date:' + amzdate + '\n' + '\n' + signed_headers + '\n' + payload_hash
要求:
headers = {
'x-amz-access-token': access,
'x-amz-date':amzdate,
'Authorization':authorization_header,
'Content-Type': 'application/json'
}
data = {
'marketplaceIds':'ATVPDKIKX0DER',
'reportType': 'GET_SALES_AND_TRAFFIC_REPORT',
'dataStartTime':'2022-03-10T20:11:24.000Z',
'dataEndTime':'2022-03-20T20:11:24.000Z',
'reportOptions':{
'dateGranularity':'WEEK',
'asinGranularity':'CHILD'
}
}
r = requests.post(
'https://sellingpartnerapi-na.amazon.com/reports/2021-06-30/reports',
headers = headers,
data = data
)
print(r)
print(r.text)
回复:
<Response [400]>
{
"errors": [
{
"code": "InvalidInput",
"message": "Invalid Input",
"details": ""
}
]
}
我花了一段时间才让签名的东西在邮递员中工作,只看你的请求,我相信 MarketplaceIds 需要是一个数组,但如果这是主要问题,你会得到一个特定的错误:
"marketplaceIds": [
"ATVPDKIKX0DER"
]
我只是在做这个。 因此,我使用 AWS4Auth 创建了一个规范字符串,以确保我没有弄乱它。
import json
import boto3
from requests_aws4auth.aws4auth import AWS4Auth
client = boto3.client('sts')
aws_account_id = 'YOUR_ACCOUNT_ID'
iamrole = 'arn:aws:iam::'+aws_account_id+':role/YOU_ROLE_NAME'
response = client.assume_role(
RoleArn= iamrole,
RoleSessionName='SPAPIRoleSession'
)
# Initializing AccessKey, SecretKey and SessionToken variables to be used in signature signing.
AccessKeyId = response['Credentials']['AccessKeyId']
SecretAccessKey = response['Credentials']['SecretAccessKey']
SessionToken = response['Credentials']['SessionToken']
#add your region accordingly: my region is us-east-1
auth = AWS4Auth(AccessKeyId, SecretAccessKey, 'us-east-1', 'execute-api', session_token=SessionToken)
# Create headers to add to SP API request. Headers should include: content_type and "x-amz-access-token"(b)
headers = {'content-type': 'application/json','Accept': 'application/json','x-amz-access-token':access}
#your params: I made a small change to 'dataEndTime', if you mentioned the granularity as a week, make sure the start and end dates are 7 days apart. Look at the AWS documentation for more details
data = {
'marketplaceIds':'ATVPDKIKX0DER',
'reportType': 'GET_SALES_AND_TRAFFIC_REPORT',
'dataStartTime':'2022-03-10T20:11:24.000Z',
'dataEndTime':'2022-03-17T20:11:24.000Z',
'reportOptions':{
'dateGranularity':'WEEK',
'asinGranularity':'CHILD'}
}
# Change data to json and add auth as additional parameter
reportId = requests.post("https://sellingpartnerapi-na.amazon.com/reports/2021-06-30/reports",
json=(data),
headers=headers,
auth=auth)
print(reportId)
print(reportId.json())
回复:
<Response [202]>
{'reportId': '54120019456'}
这应该会为您提供所需的 reportId。 让我知道这是否有帮助。 谢谢
