报错：

java.lang.IllegalArgumentException: a header name can only contain “token” characters, but found invalid character 0x7b at index 0 of header ‘{’.

分析

这是一个非常经典的 HTTP 协议格式错误。

原因分析： HTTP 协议（以及 PyCharm 的 .http 文件格式）强制要求在 请求头（Headers） 和 请求体（Body） 之间必须有一个空行。

你当前的代码中，Content-Type: application/json 紧接着就是 {。服务器解析器没有读到空行，所以它认为 { 也是一个 HTTP Header 的名字，但 { (ASCII 0x7b) 是非法字符，所以报错。

解决方法： 在 Content-Type 和 JSON 的第一个 { 之间加一个空行。

出现java.lang.IllegalArgumentException: Invalid character found in the request target应该如何解决

今天遇到一个问题: 原因： 查了资料，大部分都说是新的标准中，请求不支持“{}”,但是把大括号转义之后还是出现同样的问题，后来把中括号转义后就可以了。找到问题的原因了： 由于json中带有“[]”，请求会被tomcat拦截。 所以解决办法 1.可以使用低版本的tomcat解决该问题 2.如果使用高版本的tomcat 则需要再tomcat的config文件下的catalina.properties中加上一句 tomcat.util.http.parser.HttpParser.reque
