Question

如何将具有逗号的文本文件转换为由这些逗号分隔的数组？例如，我使用

General:
Request URL: http://192.168.0.23/login.php
Request Method: POST
Status Code: 200 OK
Remote Address: 192.168.0.23:80
Referrer Policy: no-referrer-when-downgrade

Response Headers:
Connection: Keep-Alive
Content-Encoding: gzip
Content-Length: 135
Content-Type: text/html; charset=UTF-8
Date: Sat, 10 Nov 2018 22:01:13 GMT
Keep-Alive: timeout=5, max=100
Server: Apache/2.4.10 (Raspbian)
Vary: Accept-Encoding

Request Headers:
POST /login.php HTTP/1.1
Host: 192.168.0.23
Connection: keep-alive
Content-Length: 41
Cache-Control: max-age=0
Origin: http://192.168.0.23

Form Data:
username: admin
password: letmein
Login: Login

这显然会显示以下内容： var = importdata(filename) disp(var)

然后如何使'please, help, me'成为数组，以便可以使用类似于var的东西提取单个单词？

Answer 1

使用strsplit（要求≥R2013a）或split（要求≥R2016b）将字符数组var{1}拆分为一个单元格数组，该单元格数组在单独的单元格中包含这些单词。

v = strsplit(var{1},', ');   %or v = split(var{1},' ,');

现在v{1}，v{2}和v{3}分别给'please'，'help'和'me'。
使用var{1}是因为必须从importdata返回单元格数组var。如果var不是单元格数组而是字符数组，那么您将不会在disp的输出中得到单引号。
