Python(35):Python3 通过https上传文件和下载文件

Python http方式的下载，参考：https://blog.csdn.net/fen_fen/article/details/113753983

https需要先安装需要的模块

1、上传示例

1.1、调用：

upload_strategy(access_token,"123456789")

1.2、上传代码

global pkcs12_filename, pkcs12_password
pkcs12_filename = './conf/xxx-client-cert-xxx.p12'
pkcs12_password = 'xxx'
self.host=10.1.1.101



# 上传文件
    def upload_file(self, access_token,appid):
        #warnings.simplefilter('ignore', ResourceWarning)
        # filepath = os.getcwd()
        # print(filepath)
        # print(filepath+"\data\\"+fileName)
        try:
            header_up = {"Authorization": "Bearer " + access_token}
            file=open("./data/"+fileName, "rb")
            files={"file": file}
            #files = {"file": open("./data/"+fileName, "rb")}
            url = "https://"+self.host+"/xxx/v1/xxx/strategy/xxx?appId="+appid

            api_json = base_request.upload_request(url, header_up, files)
            if api_json["code"] == 0:
                print(">>上传策略成功。")
            else:
                print(">>上传策略失败，", api_json)
            file.close()
            return api_json
        except Exception as e:
            print(">>上传策略失败，Exception:", e)

# 基础请求:上传
def upload_request(url, headers, files):
    response = requests_pkcs12.post(url, headers=headers, files=files,
                                    pkcs12_filename=pkcs12_filename,
                                    pkcs12_password=pkcs12_password, verify=False)
    api_json = response.json()  # 获取请求返回实际结果的json串值
    return api_json

2、下载示例

 2.1、下载调用：

   self.host=10.1.1.101
 
    # 下载客户端
    def download_client(self, header_all):
        try:
            url = "https://" + self.host + "/xxx/v1/xxx/download-client"
            getfile = Getfile(url, header_all)
            filename = getfile.getfilename()
            #print(filename)
            if filename:
                getfile.download(filename)

        except Exception as e:
            print(">>下载客户端失败，Exception: ", e)


header_all = {"Content-Type": "application/json;charset=UTF-8"}
header_all['Authorization'] = "Bearer " + access_token
download_client(header_all)

2.2、Python3 https下载文件工具类：
