python接口测试操作myslq

一、在配置文件中，配置好mysql信息：

cfg.ini中mysql内容如下：

[DATABASE]
host = 50.23.190.57
username = xxxxxx
password = ******
port = 3306
database = databasename

二、读取cfg.ini中的内容：

readCfg.py内容如下：

import os
import codecs
import configparser

proDir = os.path.split(os.path.realpath(__file__))[0]
configPath = os.path.join(proDir, "config.ini")

class ReadConfig:
    def __init__(self):
        fd = open(configPath)
        data = fd.read()

        #  remove BOM
        if data[:3] == codecs.BOM_UTF8:
            data = data[3:]
            file = codecs.open(configPath, "w")
            file.write(data)
            file.close()
        fd.close()

        self.cf = configparser.ConfigParser()
        self.cf.read(configPath)

    def get_email(self, name):
        value = self.cf.get("EMAIL", name)
        return value

    def get_http(self, name):
        value = self.cf.get("HTTP", name)
        return value

    def get_db(self, name):
        value = self.cf.get("DATABASE", name)
        return value

三、封装需要操作的mysql脚本：

configdb.py内容如下：

import pymysql
import readConfig as readConfig
from common.Log import MyLog as Log

localReadConfig = readConfig.ReadConfig()

class MyDB:
    global host, username, password, port, database, config
    host = localReadConfig.get_db("host")
    username = localReadConfig.get_db("username")
    password = localReadConfig.get_db("password")
    port = localReadConfig.get_db("port")
    database = localReadConfig.get_db("database")
    config = {
        'host': str(host),
        'user': username,
        'passwd': password,
        'port': int(port),
        'db': database
    }

    def __init__(self):
        self.log = Log.get_log()
        self.logger = self.log.get_logger()
        self.db = None
        self.cursor = None

    def connectDB(self):
        try:
            # connect to DB
            self.db = pymysql.connect(**config)
            # create cursor
            self.cursor = self.db.cursor()
            print("Connect DB successfully!")
        except ConnectionError as ex:
            self.logger.error(str(ex))

    def executeSQL(self, sql, params):
        self.connectDB()
        # executing sql
        self.cursor.execute(sql, params)
        # executing by committing to DB
        self.db.commit()
        return self.cursor

    def get_all(self, cursor):
        value = cursor.fetchall()
        return value

    def get_one(self, cursor):
        value = cursor.fetchone()
        return value

    def closeDB(self):
        self.db.close()
        print("Database closed!")

四、封装调用configdb.py的脚本

common.py内容如下：

import os
from xlrd import open_workbook
from xml.etree import ElementTree as ElementTree
from common.Log import MyLog as Log

localConfigHttp = configHttp.ConfigHttp()
log = Log.get_log()
logger = log.get_logger()

# 从excel文件中读取测试用例
def get_xls(xls_name, sheet_name):
    cls = []
    # get xls file's path
    xlsPath = os.path.join(proDir, "testFile", xls_name)
    # open xls file
    file = open_workbook(xlsPath)
    # get sheet by name
    sheet = file.sheet_by_name(sheet_name)
    # get one sheet's rows
    nrows = sheet.nrows
    for i in range(nrows):
        if sheet.row_values(i)[0] != u'case_name':
            cls.append(sheet.row_values(i))
    return cls

# 从xml文件中读取sql语句
database = {}
def set_xml():
    if len(database) == 0:
        sql_path = os.path.join(proDir, "testFile", "SQL.xml")
        tree = ElementTree.parse(sql_path)
        for db in tree.findall("database"):
            db_name = db.get("name")
            # print(db_name)
            table = {}
            for tb in db.getchildren():
                table_name = tb.get("name")
                # print(table_name)
                sql = {}
                for data in tb.getchildren():
                    sql_id = data.get("id")
                    # print(sql_id)
                    sql[sql_id] = data.text
                table[table_name] = sql
            database[db_name] = table

def get_xml_dict(database_name, table_name):
    set_xml()
    database_dict = database.get(database_name).get(table_name)
    return database_dict

def get_sql(database_name, table_name, sql_id):
    db = get_xml_dict(database_name, table_name)
    sql = db.get(sql_id)
    return sql
