Description
Our .net client stores a long id of 5. Before saving the id however, we convert it to big endian byte[] of 12 in length (to be the same size of mongo object id) for future proofing. This however should not matter as the following is clearly self explanatory.
See "steps to reproduce"
I actually use these JS functions as a work-around which allows me to call:
mongos> BinData(0, hexToBase64(pad((5).toString(16), 24, 0)))
|
BinData(0,"AAAAAAAAAAAAAAAF")
|
|
|
//custom JS function definition begins:
|
|
|
function pad(n, width, z) {
|
z = z || '0';
|
n = n + '';
|
return n.length >= width ? n : new Array(width - n.length + 1).join(z) + n;
|
}
|
|
|
function btoa(bin) {
|
var tableStr = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";
|
var table = tableStr.split("");
|
for (var i = 0, j = 0, len = bin.length / 3, base64 = []; i < len; ++i) {
|
var a = bin.charCodeAt(j++), b = bin.charCodeAt(j++), c = bin.charCodeAt(j++);
|
if ((a | b | c) > 255) throw new Error("String contains an invalid character");
|
base64[base64.length] = table[a >> 2] + table[((a << 4) & 63) | (b >> 4)] +
|
(isNaN(b) ? "=" : table[((b << 2) & 63) | (c >> 6)]) +
|
(isNaN(b + c) ? "=" : table[c & 63]);
|
}
|
return base64.join("");
|
};
|
|
|
function hexToBase64(str) {
|
return btoa(String.fromCharCode.apply(null,
|
str.replace(/\r|\n/g, "").replace(/([\da-fA-F]{2}) ?/g, "0x$1 ").replace(/ +$/, "").split(" "))
|
);
|
}
