Can't set request header in json format

{"a":"b""c"}
这不是一个合法的json格式吧?
试试{"a":"b""c"}
以{开始的header,feign会认为是表达式,会按照
https://datatracker.ietf.org/doc/html/rfc6570#section-3.2.2
的规则处理的

Regardless of whether the json format is correct or not, the example I gave above already shows that the header has been parsed as the wrong string, my problem is that the header should support json format, and should not be parsed as a template even if it has {}. In addition, the link you gave is the URI Template specification, not the HTTP Header specification which is showed here: https://datatracker.ietf.org/doc/html/rfc2616#section-4.2
