我正在尝试使用 Google Indexing API 通过 python 索引我的网站 URL。我对编码不太了解，所以我从一个站点复制了这段代码。

当我在 csv 格式似乎有问题之前搜索此错误代码时？

我的 csv 格式如下“url”，然后是新行（第二列为空）。

代码如下：

from oauth2client.service_account import ServiceAccountCredentials
import httplib2
import json

import pandas as pd

# https://developers.google.com/search/apis/indexing-api/v3/prereqs#header_2
JSON_KEY_FILE = "/content/astute-tractor-329613-1baed60ec1c0.json"
SCOPES = ["https://www.googleapis.com/auth/indexing"]

credentials = ServiceAccountCredentials.from_json_keyfile_name(JSON_KEY_FILE, scopes=SCOPES)
http = credentials.authorize(httplib2.Http())

def indexURL(urls, http):
    # print(type(url)); print("URL: {}".format(url));return;

    ENDPOINT = "https://indexing.googleapis.com/v3/urlNotifications:publish"
    
    for u in urls:
        # print("U: {} type: {}".format(u, type(u)))
    
        content = {}
        content['url'] = u.strip()
        content['type'] = "URL_UPDATED"
        json_ctn = json.dumps(content)    
        # print(json_ctn);return
    
        response, content = http.request(ENDPOINT, method="POST", body=json_ctn)

        result = json.loads(content.decode())

        # For debug purpose only
        if("error" in result):
            print("Error({} - {}): {}".format(result["error"]["code"], result["error"]["status"], result["error"]["message"]))
        else:
            print("urlNotificationMetadata.url: {}".format(result["urlNotificationMetadata"]["url"]))
            print("urlNotificationMetadata.latestUpdate.url: {}".format(result["urlNotificationMetadata"]["latestUpdate"]["url"]))
            print("urlNotificationMetadata.latestUpdate.type: {}".format(result["urlNotificationMetadata"]["latestUpdate"]["type"]))
            print("urlNotificationMetadata.latestUpdate.notifyTime: {}".format(result["urlNotificationMetadata"]["latestUpdate"]["notifyTime"]))

"""
data.csv has 2 columns: URL and date.
I just need the URL column.
"""
csv = pd.read_csv("/content/indekseerida-1.csv")
csv[["URL"]].apply(lambda x: indexURL(x, http))

它给了我这些错误：

只是为了修复错误，您可以更换

csv[["URL"]].apply(lambda x: indexURL(x, http))

和

indexURLNew = lambda x: indexURL(x, http)
result_iterator = map(indexURLNew, csv["URL"])
print(list(result_iterator))

result_iterator 是一个迭代器，您可以从中获取结果
