序
本文主要研究一下spring boot tomcat的maxHttpFormPostSize參數(shù)
parseParameters
tomcat-embed-core-9.0.37-sources.jar!/org/apache/catalina/connector/Request.java
/**
* Parse request parameters.
*/
protected void parseParameters() {
parametersParsed = true;
Parameters parameters = coyoteRequest.getParameters();
boolean success = false;
try {
// Set this every time in case limit has been changed via JMX
parameters.setLimit(getConnector().getMaxParameterCount());
// getCharacterEncoding() may have been overridden to search for
// hidden form field containing request encoding
Charset charset = getCharset();
boolean useBodyEncodingForURI = connector.getUseBodyEncodingForURI();
parameters.setCharset(charset);
if (useBodyEncodingForURI) {
parameters.setQueryStringCharset(charset);
}
// Note: If !useBodyEncodingForURI, the query string encoding is
// that set towards the start of CoyoyeAdapter.service()
parameters.handleQueryParameters();
if (usingInputStream || usingReader) {
success = true;
return;
}
String contentType = getContentType();
if (contentType == null) {
contentType = "";
}
int semicolon = contentType.indexOf(';');
if (semicolon >= 0) {
contentType = contentType.substring(0, semicolon).trim();
} else {
contentType = contentType.trim();
}
if ("multipart/form-data".equals(contentType)) {
parseParts(false);
success = true;
return;
}
if( !getConnector().isParseBodyMethod(getMethod()) ) {
success = true;
return;
}
if (!("application/x-www-form-urlencoded".equals(contentType))) {
success = true;
return;
}
int len = getContentLength();
if (len > 0) {
int maxPostSize = connector.getMaxPostSize();
if ((maxPostSize >= 0) && (len > maxPostSize)) {
Context context = getContext();
if (context != null && context.getLogger().isDebugEnabled()) {
context.getLogger().debug(
sm.getString("coyoteRequest.postTooLarge"));
}
checkSwallowInput();
parameters.setParseFailedReason(FailReason.POST_TOO_LARGE);
return;
}
byte[] formData = null;
if (len < CACHED_POST_LEN) {
if (postData == null) {
postData = new byte[CACHED_POST_LEN];
}
formData = postData;
} else {
formData = new byte[len];
}
try {
if (readPostBody(formData, len) != len) {
parameters.setParseFailedReason(FailReason.REQUEST_BODY_INCOMPLETE);
return;
}
} catch (IOException e) {
// Client disconnect
Context context = getContext();
if (context != null && context.getLogger().isDebugEnabled()) {
context.getLogger().debug(
sm.getString("coyoteRequest.parseParameters"), e);
}
parameters.setParseFailedReason(FailReason.CLIENT_DISCONNECT);
return;
}
parameters.processParameters(formData, 0, len);
} else if ("chunked".equalsIgnoreCase(
coyoteRequest.getHeader("transfer-encoding"))) {
byte[] formData = null;
try {
formData = readChunkedPostBody();
} catch (IllegalStateException ise) {
// chunkedPostTooLarge error
parameters.setParseFailedReason(FailReason.POST_TOO_LARGE);
Context context = getContext();
if (context != null && context.getLogger().isDebugEnabled()) {
context.getLogger().debug(
sm.getString("coyoteRequest.parseParameters"),
ise);
}
return;
} catch (IOException e) {
// Client disconnect
parameters.setParseFailedReason(FailReason.CLIENT_DISCONNECT);
Context context = getContext();
if (context != null && context.getLogger().isDebugEnabled()) {
context.getLogger().debug(
sm.getString("coyoteRequest.parseParameters"), e);
}
return;
}
if (formData != null) {
parameters.processParameters(formData, 0, formData.length);
}
}
success = true;
} finally {
if (!success) {
parameters.setParseFailedReason(FailReason.UNKNOWN);
}
}
}tomcat request解析表單參數(shù)
maxPostSize
主要是下面這段
if ((maxPostSize >= 0) && (len > maxPostSize)) {
Context context = getContext();
if (context != null && context.getLogger().isDebugEnabled()) {
context.getLogger().debug(
sm.getString("coyoteRequest.postTooLarge"));
}
checkSwallowInput();
parameters.setParseFailedReason(FailReason.POST_TOO_LARGE);
return;
}如果大于maxPostSize，則會(huì)設(shè)置FailReason.POST_TOO_LARGE，如果開(kāi)啟debug日志則會(huì)打印coyoteRequest.postTooLarge的內(nèi)容
postTooLarge
coyoteRequest.postTooLarge=Parameters were not parsed because the size of the posted data was too big. Use the maxPostSize attribute of the connector to resolve this if the application should accept large POSTs.
400
對(duì)于spring boot來(lái)說(shuō)，請(qǐng)求會(huì)報(bào)400，也就是參數(shù)丟失的錯(cuò)誤，比如

}The maximum size in bytes of the POST which will be handled by the container FORM URL parameter parsing. The limit can be disabled by setting this attribute to a value less than zero.

}The maximum number of request body bytes (excluding transfer encoding overhead) that will be swallowed by Tomcat for an aborted upload. An aborted upload is when Tomcat knows that the request body is going to be ignored but the client still sends it. If Tomcat does not swallow the body the client is unlikely to see the response. If not specified the default of 2097152 (2 megabytes) will be used. A value of less than zero indicates that no limit should be enforced.
小結(jié)
tomcat提供了maxPostSize及maxSwallowSize兩個(gè)參數(shù)，其中maxPostSize用于限制post表單請(qǐng)求大小，默認(rèn)2M，而maxSwallowSize用于限制aborted upload能夠swallowed的大小。在springboot的2.3.3版本的話，通過(guò)server.tomcat.max-http-form-post-size來(lái)指定maxPostSize大小。
