如何将Google电子表格的工作表字符串ID转换为整数索引(GID)？

Question

要将Google电子表格的单个工作表导出为CSV,需要传递整数工作表索引(GID).

https://spreadsheets.google.com/feeds/download/spreadsheets/Export?key=%s&gid=%d&exportFormat=csv

但是,那些信息在哪里？使用gdata.spreadsheets.client,我可以找到工作表的一些字符串id,如"oc6,ocv,odf".

client = gdata.spreadsheets.client.SpreadsheetsClient()
feed = client.GetWorksheets(spreadsheet, auth_token=auth_token)

它返回原子XML下面.(一部分)

</entry>

我也尝试使用sheet参数但是因"Invalid Sheet"错误而失败.

https://spreadsheets.google.com/feeds/download/spreadsheets/Export?key=%s&sheet=XXX&exportFormat=csv

我想应该有一些神奇的功能,但找不到它.我怎样才能将它们转换为整数id？或者我可以导出带有字符串ID的工作表吗？

编辑:我刚刚用python制作了转换表.很脏但工作:-(

Answer 1

我发现你的问题正在寻找同一问题的解决方案,并且惊讶于那些工作表ID实际上与1:1对应gids- 我最初认为它们是独立分配的,而不是混淆的练习.

我通过对他们用来从表中生成工作表ID的公式进行逆向工程,找到了一个稍微清晰的解决方案:

worksheetID = (gid xor 31578) encoded in base 36

所以,一些Python从工作表ID转到gid:

def to_gid(worksheet_id):
    return int(worksheet_id, 36) ^ 31578

这仍然很脏,但是对于高于99的GID而言不需要巨型表格.至少只要它们不改变生成逻辑(它们可能不会改变它们,因为它会破坏人们已经使用的现有ID).

Answer 2

此代码适用于新的Google表格.

// Conversion of Worksheet Ids to GIDs and vice versa
// od4 > 2
function wid_to_gid(wid) {
    var widval = wid.length > 3 ? wid.substring(1) : wid;
    var xorval = wid.length > 3 ? 474 : 31578;
    return parseInt(String(widval), 36) ^ xorval;
}
// 2 > od4
function gid_to_wid(gid) {
    var xorval = gid > 31578 ? 474 : 31578;
    var letter = gid > 31578 ? 'o' : '';
    return letter + parseInt((gid ^ xorval)).toString(36);
}

Answer 3

我无法在Wasilewski的帖子中添加评论,因为显然我缺乏声誉所以这里是基于Wasilewski答案的Javascript中的两个转换函数:

// Conversion of Worksheet Ids to GIDs and vice versa
// od4 > 2
function wid_to_gid(wid) {
    return parseInt(String(wid),36)^31578
}
// 2> 0d4
function gid_to_wid(gid) {
    // (gid xor 31578) encoded in base 36
    return parseInt((gid^31578)).toString(36);
}
