Question

这是问题的要点。我正在尝试从REST API调用中获取数据并将它们存储在数据库中。然后我运行几个查询来找出TOP 3用户。我无法将从MySQL获取的所有列表值打包到JSON文件中。

我无法解决以下问题。

文件＆＃34; /Users/id1/Downloads/user1.py"，第58行，在   get_last_three_installed_user       results.append（dict（zip（columns，row）））

TypeError：＆＃39; unicode＆＃39;对象不可调用

这是SQL查询的输出

+----------------+--------+-------------+------------+-----------------+
| name           | gender | nationality | registered | registered_date |
+----------------+--------+-------------+------------+-----------------+
| mélissa robin  | female | FR          | 1437761753 | 2015-07-24      |

| soline morin   | female | FR          | 1436138376 | 2015-07-05      |

如果我尝试str（名称），我会收到以下错误：

name = str（json_dict [＆＃34; results＆＃34;] [result] [＆＃34; user＆＃34;] [＆＃34; name＆＃34;] [＆＃34; first＆＃34; ]）+＆＃34;   ＆＃34; + str（json_dict [＆＃34;结果＆＃34;] [结果] [＆＃34;用户＆＃34;] [＆＃34;名称＆＃34;] [＆＃34;最后＆＃34; ]）

UnicodeEncodeError：＆＃39; ascii＆＃39;编解码器不能对字符u＆＃39; \ xe4＆＃39;进行编码。在   位置1：序数不在范围内（128）

这是我的代码：

def get_last_three_installed_user(file_type):
    count_sql = "select name,gender,nationality,registered,DATE_FORMAT(from_unixtime(registered), '%Y-%m-%d') registered_date from install_user order by from_unixtime(registered) desc limit 3 "
    curs.execute(count_sql)
    columns = [column[0] for column in curs.description]
    results = []

    if file_type == 'csv':
        fp = open('user_list.csv', 'w')
        csvFile = csv.writer(fp)
        rows = curs.fetchall()
        csvFile.writerows(rows)
    else:
        with open('file_count.json', 'w') as outfile:
            for row in curs.fetchall():
               results.append(dict(zip(columns, row)))
               print results
            output = {"TableData": results}
            json.dump(output, outfile, sort_keys = True, indent = 4, ensure_ascii=False)

这段代码非常关注它。

def get_last_three_installed_user(file_type):
    count_sql = "select name,gender,nationality,registered,DATE_FORMAT(from_unixtime(registered), '%Y-%m-%d') registered_date from install_user order by from_unixtime(registered) desc limit 1,3 "
    curs.execute(count_sql)
    results = []
    dict1 ={}

    if file_type == 'csv':
        fp = open('user_list.csv', 'w')
        csvFile = csv.writer(fp)
        rows = curs.fetchall()
        csvFile.writerows(rows)
    else:
        with open('file_count.json', 'w') as outfile:
            for row in curs.fetchall():
                for idx, col in enumerate(curs.description):
                    dict1[col[0]] = row[idx]
                results.append(dict1)
            output = {"TableData": results}
            json.dump(output, outfile, sort_keys = True, indent = 4, ensure_ascii=False)
