数据都对的,和后台联调,接口一直返回验签失败,和后端对了一下午,都没找出问题。。。
仔细比对了报文,发现我这边请求的文本里面的=变成了\u003d\u003d,而后端贴给我的报文是==
查看了几个帖子,发现问题:
我这边数据转成JSON使用的是google的Gson,Gson默认是进行HTML ESCAPE,也就是转码,因此对象中有=时,Gson就会把=转码,所以我本地的请求体中的报文是带有\u003d\u003d;而后端接收到请求之后是把数据封装成JSONObject,封装成object会将\u00
在进行web开发时,例如编写web网站,爬取网站时,经常会遇到一些字符变成了unicode码的情形。如"<"变成\u003c等,这样处理起来非常麻烦,用str.replace()函数也处理不了。为了解决这个问题,我们查找了unicode的编码机制,编写了进行转换的函数。/*

问题场景:发现json序列化之后,本来预期json ky的值为{"url":"xxx.com?param=xxx"},结果打印日志发现变成了{"url":"xxx.com?param\u003dxxx"},且代码本身并没有对“=”进行decode操作,经过排除法发现是gson序列化问题,上网搜索得知,Gson默认是进行HTML ESCAPE,也就是转码,因此对象中有=时,Gson就会把=转码;
解决方案、
1.gson设置不用HTML ESCAPE
2.使用fastjson

例如:"\

u0031\
u002D\
u0033\
u0020\
u0031\
u003A\
u0030\
u0031"是怎么转换?
现转一篇有网文,有帮助理解和自行记录
这个dao是uncode编码方dao式版 解码方式如下:权
String a ="\
u003C\
u0066\
u0072\
u006F\
u006D\
u003E";
System.out.println(new String(a.getBytes(),“utf-8”));
在Java中,比较操作符>(大于)、<(小于)、>=(大于等于)和<=(小于等于)用于比较两个值的大小。这些操作符可以用于比较基本数据类型(如int、double等)以及字符串。当对基本数据类型进行比较时,它们会根据数值的大小返回一个布尔值(true或false)。比较字符串时,它们会根据字典顺序来确定字符串的大小。
引用中提到的“>>>”运算符实际上不是比较操作符,而是位移操作符。它用于对整数进行无符号右移操作,将数值向右移动指定的位数,并在空出的高位填入0。该运算符不会区分正负数,所以它适用于处理无符号位移的情况,而不是比较大小。
综上所述,Java中的比较操作符>、<、>=和<=用于比较两个值的大小,而“>>>”运算符用于进行无符号右移操作。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
