无法解析的StackExchange API响应

Question

我编写了一个小程序来分析StackExchange API中的配置文件数据,但是api会向我发送unsarse-/unreadable数据.

收到的数据:(使用c#自行下载)

\ u001f\B\0\0\0\0\0\U0004\0mRMo0\F /:d $ C'^ {/\u0006\u0018G> \我\ u0015\U0004݀d> GRL'o\u0004G%JP\u001c-EM> 0Xbm〜\u0018tk\u0014M] rdLGv0〜FJ = 1\u00031I> kTRA \"(/ +; NL\u0018 2 H\u0014P藄XaLw#3\U0002 +\u007f\u0010\u000fp】v\u007f \吨ڧ\nf "\ u0018 \00ƺ 1x#j ^- c AX\t \u001aT @ qj \u001aU7 \u0014 \"\ a ^ \b #\ u001eQG%Y \吨חq00K\AV\u0011 {ظ\ u0005 \"\ u001d + |\u007f'\ u0016〜 8\u007f\U0001-H] O\u007fVo\u007f\U0001〜Y\U0003\U0002\0\0

想要的数据:(从我的浏览器复制粘贴)

{ "物品":[{ "badge_counts",{ "青铜":987, "银":654, "金":321}, "ACCOUNT_ID" 123456789 "is_employee":假"LAST_MODIFIED_DATE":1250612752" last_access_date ":1250540770,"年龄":0," reputation_change_year ":987," reputation_change_quarter ":654," reputation_change_month ":321," reputation_change_week ":98," reputation_change_day ":76,"信誉":9876," CREATION_DATE" :1109670518,"user_type":"registered","user_id":123456789,"accept_rate":0,"location":"Australia","website_url":" http://example.org ","link":" http://example.org/username " "profile_image":" http://example.org/username/icon.png ", "DISPLAY_NAME": "用户名"}], "has_more":假"quota_max" :300, "quota_remaining":300}

我写了这个(扩展)方法从互联网上下载字符串:

public static string DownloadString(this string link)
{
    WebClient wc = null;
    string s = null;
    try
    {
        wc = new WebClient();
        wc.Encoding = Encoding.UTF8;
        s = wc.DownloadString(link);
        return s;
    }
    catch (Exception)
    {
        throw;
    }
    finally
    {
        if (wc != null)
        {
            wc.Dispose();
        }
    }
    return null;
}

然后我搜索了互联网,找到了一种下载字符串的方法,使用其他一些策略:

public string DownloadString2(string link)
{
    WebClient client = new WebClient();
    client.Encoding = Encoding.UTF8;
    Stream data = client.OpenRead(link);
    StreamReader reader = new StreamReader(data);
    string s = reader.ReadToEnd();
    data.Close();
    reader.Close();
    return s;
}

但是这两种方法都返回相同的(未读/不可解析的)数据.

如何从API获取可读数据？有什么遗漏？

在我看来,输出是压缩的.您可以使用GZipStream可以找到的内容System.IO.Compression来解压缩字节.

public static string DownloadString(this string link)
{
    WebClient wc = null;
    try
    {
        wc = new WebClient();
        wc.Encoding = Encoding.UTF8;
        byte[] b = wc.DownloadData(link);

        MemoryStream output = new MemoryStream();
        using (GZipStream g = new GZipStream(new MemoryStream(b), CompressionMode.Decompress))
        {
            g.CopyTo(output);
        }

        return Encoding.UTF8.GetString(output.ToArray());
    }
    catch
    {

    }
    finally
    {
        if (wc != null)
        {
            wc.Dispose();
        }
    }
    return null;
}
