python封装上传图片方法执行时有告警【ResourceWarning: Enable tracemalloc to get the object allocation traceback5】

封装上传文件的时候需要的问题,使用 python os 模块

打开cmd 并执行上传文件操作之后,文件可以正常上传文件,但是会报错

ResourceWarning: unclosed file <_io.TextIOWrapper name=3 encoding='cp936'>
  os.popen(cmd)
ResourceWarning: Enable tracemalloc to get the object allocation traceback

OK

第一个解决io文件的告警需要将打开的io对象关闭即可

def upload_file(self, browser, file_path, file_exe_path=local_config.get_upload_path):
        """上传文件"""
        try:
            """上传文件"""
            exe_file = file_exe_path
            cmd = """ + exe_file + """ + " " + """ + browser + """ + " " + """ + file_path + """
            cd = os.popen(cmd)
            self.wait(2)
            cd.close() # 关闭io对象
        except Exception as e:
            logger.error("当前脚本不能执行原因是: %s" % e)
            self.screenshot_as_file()

第二个告警  

# 解决错误 ResourceWarning: Enable tracemalloc to get the object allocation traceback5

在执行文件的前面加上这段话就行了

import warnings

@classmethod
    def setUpClass(cls) -> None:
        # 解决错误 ResourceWarning: Enable tracemalloc to get the object allocation traceback5
        warnings.simplefilter('ignore', ResourceWarning)
