1.注册七牛云 2.创建七牛云的存储空间
3.配置上传的文件
from qiniu import Auth, put_data, etag#需要填写你的 Access Key 和 Secret Keyaccess_key = 'ak'secret_key = 'sk'def upload_file_qiniu(inputdata):''':param inputdata: bytes类型的数据:return: 文件在七牛的上传名字'''# 构建鉴权对象q = Auth(access_key, secret_key)#要上传的空间bucket_name = 'cars'#生成上传 Token，可以指定过期时间等token = q.upload_token(bucket_name)#如果需要对上传的图片命名，就把第二个参数改为需要的名字ret1,ret2=put_data(token,None,data=inputdata)print('ret1:',ret1)print('ret2:',ret2)#判断是否上传成功if ret2.status_code!=200:raise Exception('文件上传失败')return ret1.get('key')
4.写一个简单前端
<form method="post" enctype="multipart/form-data" action="http://127.0.0.1:5000/api/v1.0/upload_file"><input type="file" id="img" name="imgup"><button type="submit" id="btn">上传图片</button></form>
5.后端上传
@api.route('/upload_file',methods=['post','GET'])def upload_carimg():if request.method == 'GET':return render_template('car.html')if request.method == 'POST':#todo 1获取前端数据try:data = request.files.get('imgup').read()except Exception as e:return jsonify(errmsg='获取前端数据错误')#todo 2使用自定义的上传文件系统，上传图片服务器try:filename = upload_file_qiniu(data)except Exception as e:return jsonify(errmsg='上传失败',errcode=constant.RET_IMG_UPLOAD_ERR)return 'ok'
