1、在HTML测试报告的错误是这样的，改了很多地方都没解决：
ft1.1: Traceback (most recent call last):

success = self.login.user_base(‘14@qq.com’,‘user111’,‘111111’,self.file_name)

2、代码如下，和老师写的没什么两样，不知为何报错：
“get_code”
#coding = utf-8
from PIL import Image
from test1.ShowapiRequest import ShowapiRequest

class GetCode:
def init(self,driver):
self.driver = driver
# 获取图片
def get_code_image(self, file_name):
self.driver.save_screenshot(file_name) # 直接保存了这张图片
code_element = self.driver.find_element_by_id(‘getcode_num’)
# print(code_element.location) # {“x”:123,“y”:345}
left = code_element.location[‘x’]
top = code_element.location[‘y’]
right = code_element.size[‘width’] + left
height = code_element.size[‘height’] + top
im = Image.open(file_name)
# crop的作用是按照一定的坐标裁剪
img = im.crop((left, top, right, height))
img.save(file_name) # 只有一个文件
time.sleep(2)

# 解析图片获取验证码
