Briefly describe the problem

The content string returned by the calling interface is spliced and cannot be converted to json format normally:

"{\"ReturnCode\":1,\"Message\":\"\"}"

question:

Double quotes are added on both sides of the character bed", should be braces{}
In the key-value pair, the parameter name and value are double quoted, so many escaped slashes appear.\

deal with

Using the hutool tool is more convenient, and different symbols on both sides can also be defined. Discover specific functions by yourself

String string = StrUtil.strip(httpResponse.body(), "\"");
