This is just JS string escaping, which can be said to be UTF-16 encoding. Just like "A" can be written as "x41", it can also be written as "u0041". It’s just that x is followed by two digits, and u is followed by 4 digits. In ES6, curly brackets can be added for more than 4 digits. "u{10FFF}""x41" 一样，也可以写成"u0041"一样。只是 x后面跟两位是数字，u 跟4位。ES6 里面对于多余4位的可以加大括号。"u{10FFF}"
这样写是为了防止直接写{"code":1003,"msg":"缺少参数"} This is written to prevent garbled characters caused by not setting the appropriate encoding in the http header when writing {"code":1003,"msg":"missing parameters"} directly (this cannot be like Write the same as <meata charset="UTF8"> in the HTML file).

Unicode encoded
Chinese
{"code":1003,"msg":"缺少参数"}json_encode($a, JSON_UNESCAPED_UNICODE)
See the manual - http://php.net/manual/zh/function.json-encode.php
No need to worry about it, you can use it directly
Somewhat like the JSON RPC model

So, it’s written like this! 🎜{"code":1003,"msg":"缺少参数"}This is written to prevent garbled characters caused by not setting the appropriate encoding in the http header when writing
{"code":1003,"msg":"missing parameters"}directly (this cannot be like Write the same as <meata charset="UTF8"> in the HTML file).Unicode encoding. . The Chinese meaning of its parameters is: missing parameters.
Unicode, just use it
