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

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