/ / Please paste the code text below (do not replace the code with pictures)
it"s just the code for me to convert the string to byte and then construct the ArrayBuffer array to send it to websocket.
function stringToByte(str) {
var bytes = new Array();
var len, c;
len = str.length;
for (var i = 0; i < len; iPP) {
c = str.charCodeAt(i);
if (c >= 0x010000 && c <= 0x10FFFF) {
bytes.push(((c >> 18) & 0x07) | 0xF0);
bytes.push(((c >> 12) & 0x3F) | 0x80);
bytes.push(((c >> 6) & 0x3F) | 0x80);
bytes.push((c & 0x3F) | 0x80);
} else if (c >= 0x000800 && c <= 0x00FFFF) {
bytes.push(((c >> 12) & 0x0F) | 0xE0);
bytes.push(((c >> 6) & 0x3F) | 0x80);
bytes.push((c & 0x3F) | 0x80);
} else if (c >= 0x000080 && c <= 0x0007FF) {
bytes.push(((c >> 6) & 0x1F) | 0xC0);
bytes.push((c & 0x3F) | 0x80);
} else {
bytes.push(c & 0xFF);
}
}
return bytes;
}then the string is garbled in Chinese
function byteToString(arr) {
if (typeof arr === "string") {
return arr;
}
var str = "", _arr = arr;
for (var i = 0; i < _arr.length; iPP) {
var one = _arr[i].toString(2), v = one.match(/^1+?(?=0)/);
if (v && one.length == 8) {
var bytesLength = v[0].length;
var store = _arr[i].toString(2).slice(7 - bytesLength);
for (var st = 1; st < bytesLength; stPP) {
store += _arr[st + i].toString(2).slice(2);
}
str += String.fromCharCode(parseInt(store, 2));
i += bytesLength - 1;
} else {
str += String.fromCharCode(_arr[i]);
}
}
return str;
}
what result do you expect? What is the error message actually seen?
is there any solution?
