var encoder = require('qs-iconv/encoder')('shift_jis'); var shiftJISEncoded = qs.stringify({ a: 'こんにちは！' }, { encoder: encoder }); assert.equal(shiftJISEncoded, 'a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I');
这也适用于解码查询字符串：
var decoder = require('qs-iconv/decoder')('shift_jis'); var obj = qs.parse('a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I', { decoder: decoder }); assert.deepEqual(obj, { a: 'こんにちは！' });
RFC 3986 and RFC 1738 space encoding
RFC3986 used as default option and encodes ' ' to %20 which is backward compatible. In the same time, output can be stringified as per RFC1738 with ' ' equal to ‘+'.
assert.equal(qs.stringify({ a: 'b c' }), 'a=b%20c'); assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC3986' }), 'a=b%20c'); assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC1738' }), 'a=b+c');
