我想为 Python 使用亚马逊的 sell-partner-api。我按照下面 url 的提要说明进行操作，但它使用 Java 示例编码：

https://github.com/amzn/ sell-partner-api-docs/blob/main/guides/use-case-guides/feeds-api-use-case-guide-2020-09-04.md#step- 2-加密并上传-feed-data

我想上传带有制表符分隔值的纯文本。这是我遵循的步骤：

第 1 步：创建提要文档（作品）

def createFeedDocument():
    payload={'contentType':"text/tab-separated-values; charset=iso-8859-1"}
    data = json.dumps(payload)
    res = requestAmazon(getToken(),canonical_uri='/feeds/2021-06-30/documents',method='POST',payload=data)
    url = res.get('url')
    document_id = res.get('feedDocumentId')
    return [document_id,url]

requestAmazon 是一个获取标头签名并发出这样的 POST 请求的函数

r = requests.post(request_url,data=payload,headers=headers)

响应步骤 1

{'feedDocumentId'：'amzn1.tortuga.3.90f2647c-XXXXXXX'，'url'：'https://tortuga-prod-eu.s3-eu-west-1.amazonaws.com/%2FNinetyDays/amzn1.tortuga。 3.90f2647c-XXXXXXXX?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Date=20210827T063456Z&X-Amz-SignedHeaders=content-type%3Bhost&X-Amz-Expires=300&X-Amz-Credential=XXXXXX&X-Amz-Signature=XXXXXX '}

第 2 步：构建提要

我从其他部门得到了文本生成器，所以我跳过了这一步。

第 3 步：上传 Feed 数据

def createFeed():
    feedDocumentId,url = createFeedDocument()
    with open('C:\\users\\XXXXX\\Desktop\\upload.txt', 'rb') as f:
        files = {'file':('upload.txt',f)} 
        response = requests.put(url,data={'feedDocumentId':feedDocumentId},files=files)
        return response.text

第 3 步响应：
