使用zlib.js解压缩python zlib压缩

标签: javascript python zlib

在服务器端,我使用python zlib压缩字符串,如下所示:

import zlib

s = '{"foo": "bar"}'
compress = zlib.compress(s)
print compress

上一代码的结果如下

xœ«VJËÏW²RPJJ,Rª

在客户端,我使用zlib.js解压缩

var s = "xœ«VJËÏW²RPJJ,Rª"
var data = new Array(s.length);
for (i = 0, il = s.length; i < il; ++i) {
    data[i] = s.charCodeAt(i);
}
var inflate = new Zlib.Inflate(data);

我收到以下错误

zlib_and_gzip.min.js:1 Uncaught Error: invalid fcheck flag:28
    at new tb (zlib_and_gzip.min.js:48)
    at <anonymous>:1:15

我做错了什么?

答案 0 :(得分:0)

问题在于编码。在python中我用base64编码。

>>> import zlib

>>> s = '{"foo": "bar"}'
>>> compress = zlib.compress(s)
>>> print compress.encode('base64')

>>> "eJyrVkrLz1eyUlBKSixSqgUAIJgEVA=="

在客户端:

var s = atob("eJyrVkrLz1eyUlBKSixSqgUAIJgEVA==");

var data = new Array(s.length);
for (i = 0, il = s.length; i < il; ++i) {
    data[i] = s.charCodeAt(i);
}

var inflate = new Zlib.Inflate(data);
var decompress = inflate.decompress();
var plain = new TextDecoder("utf-8").decode(decompress);

plain 
"{"foo": "bar"}"

非常感谢你的帮助
