Question

我希望修改字符串的值如果字符串中的某些位置是特定值，例如我有一个邮政编码L65 OBH，我需要执行以下操作：

（1）

如果字符串第一部分中的第一个值（由空格分割）= L则需要将其更改为T.这将给出：

T65 OBH

（2）

然后，如果字符串第一部分中的第二个值（由空格分割）= 6，则需要将其更改为7.这将给出：

T75 OBH

（3）

然后，如果字符串第二部分中的第一个值（由空格分割）= O，则需要将其更改为2.这将给出：

T75 2BH

（4）

然后，如果字符串第二部分中的第3个值（由空格分割）= H，则需要将其更改为P.这将给出：

T75 2BP

我假设我需要使用replaceall和一些IF语句，但我正在努力解决这个问题，特别是如何将邮政编码的两个不同部分分开，将它们视为单独的enteties ....有人请帮忙

我会为替换规则编写辅助方法：

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

Answer 2

def strVal= "L65 OBH"
strVal.replaceFirst(/^L/, "T")

def strVal1= "L65 OBH"
strVal1.replaceFirst(/^6/, "7")

等使用相同的replaceFirst()方法
