我要照一个文件所述的需求,完成一个功能,如下: 我实在愚笨 看了好几天仍不能了解它encode,decode规则是如何...orz 这是用在websocket send/recievd binary data时要求的: Where binary data is returned from this API, it is encoded as follows: It is converted to a string by converting each byte in turn using these rules: a. Bytes 0x20 to 0x24 inclusive are mapped to the corresponding characters U+0020 to U+0024 inclusive. b. Bytes 0x26 to 0x7E inclusive are mapped to the corresponding characters U+0026 to U+007E inclusive. c. Other bytes are mapped to the three character sequence consisting of a percent character followed by two uppercase hex characters, e.g. byte 0 maps to “%00” and byte 0xAB maps to “%AB”. Where binary data is passed into this API, it is passed as a string which is decoded as follows: a. Characters U+0020 to U+0024 inclusive are mapped to the corresponding bytes 0x20 to 0x24 inclusive. b. Characters U+0026 to U+007E inclusive are mapped to the corresponding bytes 0x26 to 0x7E inclusive. c. The three character sequence consisting of a percent character followed by two uppercase hex characters maps to the corresponding byte, e.g. “%00” maps to byte 0 and “%AB” maps to byte 0xAB. d. A percent character that is not followed by two uppercase hex characters means the string is malformed. e. If the string contains a character outside the range U+0020 to U+007E inclusive then the string is malformed 可否各位强者能给我一些意见, 上网找了一些编码资料仍一头雾水... Thanks --
