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

*/

private String getContentType(String ext) {

switch (ext) {
