In the previous blog, RSA and AES were used to complete the encryption and decryption of the interface, but in the actual test process, occasionally there will be problems of `HTTP method names must be tokens`, `Connection prematurely closed BEFORE response`

The road to solution

Puzzled, Google and Baidu have been searched, but still can’t solve it, it’s useless to change the size of the request header, for example: SpringBoot: Invalid character found in method">SpringBoot: Invalid character found in methodmethod name. HTTP method names must be tokens_Moshow Zheng Kai's Blog-CSDN Blog_invalid character found in method

Another example: The problem caused by the header parameter Content-length——The understanding of HTTP long connection- Short book (

Later, by chance, I saw some ideas on deleting the request header in Gateway on stackoverflow, and after trying N times, I found that it was solved.

The solution


#Dependent base image jdk8FROM openjdk:8u275-slim#The port that needs to be exposed is the port of my project#EXPOSE 8000#author informationMAINTAINER xxxENV TZ GMT+8ENV JAR_NAME nxx.jarADD /target/$JAR_NAME $JAR_NAMEENV JAVA_OPTS -Dname=$JAR_NAME -server -Xmx512m -Xms512m -Xmn256m -Xss256k -XX:+UseConcMarkSweepGC -XX:+CMSParallelRemarkEnabled -XX:+UseFastAccessorMethods -XX:+UseCMSInitiatingOccupancyOnly -XX:CMSInitiatingOccupancyFraction=80 -XX:MetaspaceSize=256m -XX:MaxMetaspaceSize=256m -Duser.timezone=GMT+8# After starting the container, the default run command#ENTRYPOINT java $JAVA_OPTS -jar $JAR_NAME# Solution: Connection prematurely closed BEFORE response, step 1ENTRYPOINT java $JAVA_OPTS -Dreactor.netty.pool.leasingStrategy=lifo -jar $JAR_NAME


spring:cloud:# Solution: Connection prematurely closed BEFORE response, step 2gateway:# Solution: HTTP method names must be tokens I don't know whyfilter:remove-hop-by-hop:headers: Connection


So far I don’t know why, but it is solved. I hope that the passing master will answer it and give me advice.
