传输数字和字母的json字符串都可以解析有个中文的硬件那边就解析不了替换一下发数据的处理函数即可
1 原先字符串转化函数
const stringToBytes (msg) {const buffer new ArrayBuffer(msg.length)const dataView new DataView(buffer)for (var i 0; i msg.length; i) {dataView.setUint8(i, msg.charAt(i).charCodeAt())}return buffer}2 新的字符串替换函数
const stringToBytes (msg) {const bytes [];for (let i 0; i msg.length; i) {const charCode msg.charCodeAt(i);if (charCode 0x80) {bytes.push(charCode);} else if (charCode 0x800) {bytes.push(0xC0 | (charCode 6), 0x80 | (charCode 0x3F));} else if (charCode 0x10000) {bytes.push(0xE0 | (charCode 12),0x80 | ((charCode 6) 0x3F),0x80 | (charCode 0x3F));} else if (charCode 0x200000) {bytes.push(0xF0 | (charCode 18),0x80 | ((charCode 12) 0x3F),0x80 | ((charCode 6) 0x3F),0x80 | (charCode 0x3F));} else if (charCode 0x4000000) {bytes.push(0xF8 | (charCode 24),0x80 | ((charCode 18) 0x3F),0x80 | ((charCode 12) 0x3F),0x80 | ((charCode 6) 0x3F),0x80 | (charCode 0x3F));} else {bytes.push(0xFC | (charCode 30),0x80 | ((charCode 24) 0x3F),0x80 | ((charCode 18) 0x3F),0x80 | ((charCode 12) 0x3F),0x80 | ((charCode 6) 0x3F),0x80 | (charCode 0x3F));}}const buffer new Uint8Array(bytes).buffer;return buffer;}真的很神奇
