2.利用python处理成switch语句分支
import io
file = open('content.txt')
text = ''
while(True):
line = file.readline()
words = line.split('=')
if (len(words) > 1):
w_cases = words[0].replace('.', '').replace(' ', '')
w_retrun = words[1].replace(' ', '').replace('\n', '')
text += 'case "' + w_cases + '":\r\nreturn "' + w_retrun + '";\r\n'
if not line:
break;
print(text)
file.close()
w_file = open(r't.txt', 'w')
w_file.write(text)
w_file.close()
3.生成getContentType方法
/**
* 根据文件后缀设置 content type
*
* @param ext 需要小写
* @return
*/

switch (ext) {
