1、从一个页面切换到另外一个页面时，里面点击控件会报控件找不到的错误，需要循环点击直到成功的那次才算完成；
#页面切换时的装饰器def wait(func): def waited(self, *args, **kwargs): timeout = kwargs.get("timeout") print("timeout: %d" % timeout) result = None start = time.time() last = start while time.time() - start < timeout: try: result = func(self, *args, **kwargs) print("excuting %s success, break " % func.__name__) break except: if time.time() - last > 4: print("except: " + func.__name__) print(traceback.format_exc()) last = time.time() return result return waitedclass SDMS(object): def __init__(self): self.url = "http://shams171/sdms_portal/index.htm" self.page = rpa.chrome.create(self.url) @wait def waitClick(self, page, ele, **kwargs): page.click(ele)def start(): sdms = SDMS() sdms.waitClick(sdms.page, "新店", timeout=10) 上面是简化后的装饰器，之前写的装饰器太过复杂，造成每次写程序都不想用，所以需要简化后才觉得好用点。比较复杂的装饰器如下: '''1、装饰器部分，循环等待,件不管是否出现，一直等到timeout才退出循环2、wt_page = True,控件是浏览器类型； wt_page = False,控件是win32类型'''def waitDrapper(func): def waitWrapper(obj, wt_ele, **kwargs): wait_flag = False value = "" wt_page = kwargs.get("page") wt_index = kwargs.get("index") if kwargs.get("index") else 1 # index默认为1 # kwargs中修改或者增加index的值 kwargs["index"] = wt_index wt_timeout = kwargs.get("timeout") if kwargs.get("timeout") else 10 wt_logger = kwargs.get("mylogger") # print(wt_ele);print(wt_page);print(wt_index);print(wt_timeout);print(wt_logger); # 判断参数是否正确 if not wt_ele: rpa.logger.error("element is none.") return value start = time.time() last_time = start while time.time() - start < wt_timeout: if wt_page: # page类型 try: value = func(obj, wt_ele, **kwargs) if wt_logger: wt_logger.info("execute %s ( %s ) end." % (func.__name__, wt_ele)) rpa.logger.info("execute %s ( %s ) end." % (func.__name__, wt_ele)) break # 控件出现就break退出循环 except Exception: rpa.logger.error(traceback.format_exc()) if not wt_page: # win32类型 try: value = func(obj, wt_ele, **kwargs) if wt_logger: wt_logger.info("executing %s ( %s ) end." % (func.__name__, wt_ele)) rpa.logger.info("executing %s ( %s ) end." % (func.__name__, wt_ele)) break # 控件出现就break退出循环 except Exception: rpa.logger.error(traceback.format_exc()) sleep(1) # 循环等待中，要打印等待提示信息；每过6秒打印一下； if time.time() - last_time > 6: if wt_logger: wt_logger.info("waiting for %s." % wt_ele) rpa.logger.info("waiting for %s." % wt_ele) last_time = time.time() return value return waitWrapper
