我正在从 batdongsan 应用程序中抓取数据。我设法找到了api链接并尝试使用curl来获取数据

curl -H \'Content-Type:application/x-www-form-urlencoded\' -H \'charset:utf-8\' -H \'Content-Length:182\' -H \'Origin:http://batdongsan.com.vn\' -H \'Accept:application/json\' -H \'User-Agent:Dalvik/2.1.0 (Linux; U; Android 8.0.0; SM-G9500 Build/R16NW)\' -H \'Host:apimap.batdongsan.com.vn\' -H \'Connection:Keep-Alive\' -H \'Accept-Encoding:gzip\' -X POST \'http://apimap.batdongsan.com.vn/api/p_sync\' --data-binary \'ptype=38&cate=0&city=HN&dist=0&maxarea=0&minarea=0&maxprice=0&minprice=0&ward=-1&street=-1&room=-1&direct=-1&projectid=-1&sort=0&page=3&searchType=0&client=android&m=list&pagesize=21\'\n

但解码后的 gzip 是我无法理解的字符。返回文本预计为越南语字符。

有什么想法吗？

编辑1：\n我发现这是base64编码，并且我得到以下字节字符串。但仍然不知道如何解码为字符串。尝试过UTF-8

该程序的目的是解码嵌入有“embed”的img。图像 ( ) 与main.gobu.png位于同一目录中。

package main

import (
    "bytes"
    _ "embed"
    "image"
)

var (
    //go:embed bu.png
    img []byte
)

func main() {

    a  := bytes.NewBuffer(img)
    a, b, e := image.Decode()
    println(e.Error())
    //  image: unknown format

    println(b)
    //

    println(a)
    // (0x0,0x0)

    // println(string(img))
    // the text of the image seem a little different between nano

}
