首先呢，项目共差不多10个接口，测试均不会出现该异常。部署到服务器上，也并未在实际业务操作上 发生异常。
在...服务运行一段时间后，抛出该异常。这是阿里服务会有一个定时的自身检测吗？端口检测？菜鸟渣渣不懂
Springboot2.4.5 + Apache Tomcat/9.0.45 + JDK1.8.0_251
以下是最近几次的日志：

查看了对应的异常方法Http11InputBuffer.parseRequestLine，解析请求头 第二行的时候，
if (this.parsingRequestLinePhase == 2) {问题是这里抛出来的，这是啥呀呀
if (!HttpParser.isToken(this.chr)) {
this.request.protocol().setString("HTTP/1.1");
String invalidMethodValue = this.parseInvalid(this.parsingRequestLineStart, this.byteBuffer);
throw new IllegalArgumentException(sm.getString("iib.invalidmethod", new Object[]{invalidMethodValue}));
}
该部分完整的源代码
if (this.parsingRequestLinePhase == 2) {
space = false;
while(true) {
while(!space) {
if (this.byteBuffer.position() >= this.byteBuffer.limit() && !this.fill(false)) {
return false;
}
pos = this.byteBuffer.position();
this.chr = this.byteBuffer.get();
if (this.chr != 32 && this.chr != 9) {
if (!HttpParser.isToken(this.chr)) {
this.request.protocol().setString("HTTP/1.1");
String invalidMethodValue = this.parseInvalid(this.parsingRequestLineStart, this.byteBuffer);
throw new IllegalArgumentException(sm.getString("iib.invalidmethod", new Object[]{invalidMethodValue}));
}
} else {
space = true;
this.request.method().setBytes(this.byteBuffer.array(), this.parsingRequestLineStart, pos - this.parsingRequestLineStart);
}
}
this.parsingRequestLinePhase = 3;
break;
}
}
Invalid character found in method name [0x160x030x010x020x000x010x000x010xfc0x030x030xf20x990xe20xa40x190xd20xfc0x1b0x80^G0xc50xef0x1d0xb30x830x0b0x070x92meF0x1a_`0xfci0x0f0xc3~0xfd0x95] ，这个咋解析呀
后来按照网络的方式，增加了http-post缓冲区，无效的呀。
server:
port: 6013
tomcat:
# java.lang.IllegalArgumentException: Invalid character found in method name [0x030x000x00/*0xe00x000x000x000x000x00Cookie:]. HTTP method names must be tokens
# 可能解决的方案：设置max-http-form-post-size，默认2MB。
max-http-form-post-size: 10MB
最后：这怎么排查到底是哪个请求出的问题？ww
这个问题不用去管，其实就是客户端发起的HTTP请求不规范，请求数据没有按照要求编码。服务器没法解析，就给了这个DEBUG信息。你也没法去管，毕竟你没办法控制客户通过TCP往服务器提发送什么数据。
