为什么将数据导入会导致错误？

Question

我的目标是用Python3编写一个脚本，该脚本将在中推送现有表中的数据，该脚本将由调度程序每周使用一次。我想要做的是：

1. 我可以使用cURL命令成功地导入一些数据。就像这样

curl -X POST \ 'https://analyticsapi.zoho.com/api/OwnerEmail/Workspace/TableName?ZOHO_ACTION=IMPORT& ZOHO_OUTPUT_FORMAT=JSON&ZOHO_ERROR_FORMAT=JSON&ZOHO_API_VERSION=1.0&ZOHO_IMPORT_TYPE=APPEND&ZOHO_AUTO_IDENTIFY=True&ZOHO_ON_IMPORT_ERROR=ABORT&ZOHO_CREATE_TABLE=False' \ -H 'Authorization: Zoho-oauthtoken *******' \ -H 'content-type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW' \ -F ZOHO_FILE='path_to_csv'

1. 我发现Zoho Zoho报告Python客户端提供的Zoho报告Python客户端与Python3不兼容，因此，我从这里安装了一个包装好的ReportClient。
2. 下面是Zoho网站的示例示例和Python3中Zoho包装器的github测试，我实现了如下所示:有一个类来保留ENV变量

import os
from zoho_analytics_connector.report_client import ReportClient, ServerError
from zoho_analytics_connector.enhanced_report_client import EnhancedZohoAnalyticsClient


class ZohoTracking:
    LOGINEMAILID = os.getenv("ZOHOANALYTICS_LOGINEMAIL")
    REFRESHTOKEN = os.getenv("ZOHOANALYTICS_REFRESHTOKEN")
    CLIENTID = os.getenv("ZOHOANALYTICS_CLIENTID")
    CLIENTSECRET = os.getenv("ZOHOANALYTICS_CLIENTSECRET")
    DATABASENAME = os.getenv("ZOHOANALYTICS_DATABASENAME")
    OAUTH = True
    TABLENAME = "My Table"

实例化客户端类

    def get_enhanced_zoho_analytics_client(self) -> EnhancedZohoAnalyticsClient:
        assert (not self.OAUTH and self.AUTHTOKEN) or (self.OAUTH and self.REFRESHTOKEN)
        rc = EnhancedZohoAnalyticsClient(
         // Just setting email, token, etc using class above
         ... 
        )
        return rc```
Then have a method to upload data to existing table, the data_upload() function has the problem.

def enhanced_data_upload(self):
    enhanced_client = self.get_enhanced_zoho_analytics_client()
    try:
        with open("./import/tracking3.csv", "r") as f:
            import_content = f.read()
            print(type(import_content))
    except Exception as e:
        print(f"Error:Check if file exists in the import directory {str(e)}")
        return
 
    res = enhanced_client.data_upload(import_content=import_content, table_name=ZohoTracking.TABLENAME)
    assert res

Traceback (most recent call last):
  File "push2zoho.py", line 106, in <module>
    sample.enhanced_data_upload()
  File "push2zoho.py", line 100, in enhanced_data_upload
    res = enhanced_client.data_upload(import_content=import_content, table_name=ZohoTracking.TABLENAME)
  File "/Users/.../zoho_analytics_connector/enhanced_report_client.py", line 99, in data_upload
    matching_columns=matching_columns)
  File "/Users/.../site-packages/zoho_analytics_connector/report_client.py", line 464, in importData_v2
r=self.__sendRequest(url=url,httpMethod="POST",payLoad=payload,action="IMPORT",callBackData=None)
  File "/Users/.../zoho_analytics_connector/report_client.py", line 165, in __sendRequest
    raise ServerError(respObj)
  File "/Users/.../zoho_analytics_connector/report_client.py", line 1830, in __init__
    contHeader = urlResp.headers["Content-Type"]
TypeError: 'NoneType' object is not subscriptable



That is the error I receive. What am I missing in this puzzle? Help is appreciated

Answer 1

2021年2月，我在我的库中更改了继承的Zoho代码。现在是: contHeader =urlResp.headers.get(“内容-类型”，无)

这样就避免了最后的异常。
