python在mysql数据库中执行插入操作，插入json.dumps后的包含中文的json对象，数据库中文显示为Unicode

Posted 2023-03-22

"data": "text": "\u53d6\u6d88\u9759\u97f3", "result": "name": "volnotmute", "service": "control", "presenterid": "No.0:8815bc80-8301-11e5-ae25-00237d6d53e9", "event": "Voiceres", "id": 250000001
如上为插入数据库后的显示，其中text字段部分是中文，请问如何使其在数据库中显示成中文字符；

参考技术A

直接显示就是中文

s = "data": "text": "\\u53d6\\u6d88\\u9759\\u97f3", "result": "name": "volnotmute", "service": "control", "presenterid": "No.0:8815bc80-8301-11e5-ae25-00237d6d53e9", "event": "Voiceres", "id": 250000001
print(s['data']['text'])

本回答被提问者和网友采纳 参考技术B 插入时保证是中文就行了，数据库建议用utf8。 参考技术C 画皮改编自原著同名篇章。简介暂缺。 参考技术D negative
negative

插入错误 Python MySQL 连接器：执行操作失败

【中文标题】插入错误 Python MySQL 连接器：执行操作失败

【英文标题】：INSERT Error Python MySQL Connector: Failed executing the operation

【问题描述】：

我正在使用 products.json 页面抓取 shopify 商店。尝试使用 Python 连接器将抓取的产品插入我的 MySQL 数据库，但遇到以下错误：

出了点问题：执行操作失败； b'Name'

代码如下：

import json
import pandas as pd
import mysql.connector
import ScraperConfig as conf

class myScraper():

    def __init__(self, baseurl):
        self.baseurl = baseurl

    def downloadjson(self, page):
        r = requests.get(self.baseurl + f'products.json?limit=250&page=page', timeout=5)
        if r.status_code != 200:
            print('Bad status code', r.status_code)
        if len(r.json()['products']) > 0:
            data = r.json()['products']
            return data
        else:
            return

    def parsejson(self, jsondata):
        products = []

        for prod in jsondata:
            vendor = prod['vendor']
            name = prod['title']
            handle = prod['handle']
            createdDateTime = prod['created_at']
            description = prod['body_html']
            productType = prod['product_type']
            for images in prod['images']:
                vendorProductId = images['product_id']
                try:
                    imageURL = images['src']
                except:
                    imageURL = 'None'
            for variant in prod['variants']:
                item = 
                    'name': name,
                    'handle': handle,
                    'description': description,
                    'productVariantId': variant['id'],
                    'createdDateTime': createdDateTime,
                    'productType': productType,
                    'vendorProductId': vendorProductId,
                    'imageURL': imageURL,

                    'vendor': vendor
                
                products.append(item)
        return products
        
def main():
    scrape = Scraper('https://www.someshopifysite.com/')
    results = []
    for page in range(1,2):
        data = scrape.downloadjson(page)
        print('Getting page: ', page)
        try:
            results.append(scrape.parsejson(data))
        except:
            print(f'Completed, total pages = page - 1')
            break
    return results

if __name__ == '__main__':
    db = mysql.connector.connect(
        user=conf.user,
        host=conf.host,
        passwd=conf.passwd,
        database=conf.database)
    cursor = db.cursor()
    products = main()
    totals = [item for i in products for item in i]
    for p in totals:
        sql = """INSERT INTO `table` (`Name`, `Handle`, `Descritpion`, `VariantId`, `CreatedDateTime`, `ProductType`, `VendorProductId`, `ImageURL`, `Price`, `SalePrice`, `Available`, `UpdatedDateTime`, `Vendor`)

        try:
            cursor.executemany(sql, totals)
            
            print('Committed to DB')
        except mysql.connector.Error as err:
                    print("Something went wrong: ".format(err))
        db.commit() ```

【参考方案1】：

从查询的以下和所有类似部分中删除反引号：

%(`Name`)s

通常我会删除反引号，除了引用映射到关键字的列名。

【讨论】：

试过了。不幸的是没有骰子。错误：出了点问题：执行操作失败； b'名字'
