String receivedParam = URLDecoder.decode(urlencodeReceivedParam, "UTF-8"); // 会输出正确的'好'字 System.out.println(receivedParam); 从上面的两个示例中,应该不难看出,之所以前端2次编码,后端1次解码不会出现乱码,是因为前端在第1次urlencode后,数据就已经变成了纯英文,而纯英文先使用UTF-8的urlencode编...

This library includes two NEON codecs: one for regular 32-bit ARM and one for the 64-bit AArch64 with NEON, which has double the amount of SIMD registers and can do full 64-byte table lookups. These codecs encode in 48-byte chunks and decode in massive 64-byte chunks, so they had...
