Steps to reproduce this issue

When the HTTP header Content-Type: multipart/form-data; charset=utf-8; boundary=__X_PAW_BOUNDARY__, a parsing exception will occur.

What you expected to happen

Correctly parse HTTP header

Anything else

contentType should be split to list, not just substring

dubbo/dubbo-remoting/dubbo-remoting-http12/src/main/java/org/apache/dubbo/remoting/http12/message/DefaultHttpRequest.java

Lines 242 to 257 in 403e127

	public String charset() {
	String charset = this.charset;
	if (charset == null) {
	String contentType = contentType();
	if (contentType == null) {
	charset = StringUtils.EMPTY_STRING;
	} else {
	int index = contentType.lastIndexOf(HttpUtils.CHARSET_PREFIX);
	charset = index == -1
	? StringUtils.EMPTY_STRING
	: contentType.substring(index + 8).trim();
	}
	this.charset = charset;
	}
	return charset.isEmpty() ? null : charset;
	}
