Question

我在循环中查询API时出现问题，其中字符串索引必须是整数，而不是str。

我想知道是否有人可以就下面的错误提出建议？

所以，这是错误：

for

基本上，我所做的是使用下面的audience_stats（）函数循环遍历single_audience_stats（）函数。

/home/slauw/lotame_api_test/lotame_api_functions.pyc in audience_stats(config_filepath, date_today)
    185     print("aud_stats begun, current row length = " + str(len(aud_stats.index)))
    186     for i in ids:
--> 187         current_aud_stats = single_audience_stats(config_filepath, i, date_today)
    188         aud_stats = aud_stats.append(current_aud_stats)
    189         print("id " + i + " added, current row length = " + str(len(aud_stats.index)))

/home/slauw/lotame_api_test/lotame_api_functions.pyc in single_audience_stats(config_filepath, audience_id, date_today)
    151     query_string = "statistics/audiences/" + audience_id + "?client_as_group=true&date_range=LAST_30_DAYS&generate_stats=now&device_graph=false&page_count=100&page_num=1&sort_attr=data_date&sort_order=ASC"
    152     query_result = get_query(query_string, config_filepath)
--> 153     audienceStats = query_result["audienceStatsReports"]
    154     statsTable = []
    155     a_obj = {}

Config_filepath基本上只是登录API的身份验证，而date_today是通过time.strftime（“％Y-％m-％d）”创建的。

get_query（）函数基本上是使用配置文件帮助连接API的函数。

- 更新：所以在query_result结束时，我会得到'dict'类型。

以下是它的样子：

def audience_stats(config_filepath, date_today):
    id_query_string = "audiences?page_count=500&page_num=1&sort_order=ASC&sort_attr=id&or=true"
    id_query_result = get_query(id_query_string, config_filepath)
    audiences = id_query_result["Audience"]
    first_id = audiences[0]["id"]
    print("first id: " + first_id)
    audiences = audiences[1:]
    ids = []
    for a in audiences:
        ids.append(a["id"])
    print("ids: " + str(ids))
    aud_stats = single_audience_stats(config_filepath, first_id, date_today)
    print("aud_stats begun, current row length = " + str(len(aud_stats.index)))
    for i in ids:
        current_aud_stats = single_audience_stats(config_filepath, i, date_today)
        aud_stats = aud_stats.append(current_aud_stats)
        print("id " + i + " added, current row length = " + str(len(aud_stats.index)))
    print("loop complete")
    return aud_stats

def single_audience_stats(config_filepath, audience_id, date_today):
    query_string = "statistics/audiences/" + audience_id + "?client_as_group=true&date_range=LAST_30_DAYS&generate_stats=now&device_graph=false&page_count=100&page_num=1&sort_attr=data_date&sort_order=ASC"
    query_result = get_query(query_string, config_filepath)
    audienceStats = query_result["audienceStatsReports"]
    statsTable = []
    a_obj = {}
    keys = ["audienceId", "audienceName", "averageDailyUsers", "uniques", "pageViews"]
    if (len(audienceStats) > 0):
        a = audienceStats[0]
        for key in keys:
            if key in a.keys():
                a_obj[key] = a[key]
            else:
                a_obj[key] = ""
    else:
        for key in keys:
            a_obj[key] = ""
    a_obj["date"] = date_today
    statsTable.append(a_obj)
    stats_df = pd.DataFrame(statsTable)
    return stats_df

任何人都可以帮助解决上述问题吗？
