Python如何向SQLServer存储二进制图片

需求是需要用python往 SqlServer中的image类型字段中插入二进制图片

核心代码，研究好几个小时的代码：

安装pywin32，adodbapi image_url = "图片链接" try: image_result = session.get(url=image_url, headers=headers, stream=True) except: image_result = session.get(url=image_url, headers=headers, stream=True) local_filename = md5(image_url) + ".png" print "图片下载成功" with open(local_filename, 'wb') as f: for chunk in image_result.iter_content(chunk_size=1024): if chunk: # filter out keep-alive new chunks f.write(chunk) f.flush() f.close() # 读取图片，二进制格式，注意是rb f1 = open(local_filename, "rb", ) b = f1.read() f1.close() # adodbapi支持插入二进制数据流 Cfg = {'server': 'XXXXXXX9', 'password': 'XXXXXXX', 'db': 'XXXXXXX'} constr = "Provider=SQLOLEDB.1; Initial Catalog=%s; Data Source=%s; user ID=%s; Password=%s; " % (Cfg['db'], Cfg['server'], 'drc_sql', Cfg['password']) conn = adodbapi.connect(constr) cursor = conn.cursor() print "DocId", DocId # docimageid在数据表是主键 docimageid = str(DocId) + str(image_location) print "docimageid", docimageid sql6 = " INSERT INTO docImages (DocId,docimageid,purpose) VALUES (%s,'%s','%s') " % (int(DocId), int(docimageid), 'doclogo') # print sql6 cursor.execute(sql6) conn.commit() #插入图片 cursor.execute('update docImages set Img=? where docimageid= ? ',(adodbapi.Binary(b), docimageid,)) conn.commit() print "图片保存成功" 先插入相关信息，再去update图片到数据库里面。
