Question

我正在构建Chrome扩展程序，该扩展程序应该编辑Google电子表格中的单元格。我设法读取工作表内容但无法编辑单元格。目前我的错误是“400（错误请求）”。知道我在这里做错了吗？

我在此处查看了Google表格API文档和其他已发布的问题，但无法找到任何解决方案。

以下是我用来获取工作表内容的代码（这可行）：

function loadSpreadsheet(token) {

    var y = new XMLHttpRequest();
    y.open('GET', 'https://spreadsheets.google.com/feeds/list/1NE8g7kyk-Z6Sci9_w6mdY2KV8542a3TJd9lIbucHZiU/default/private/values?access_token=' + token);
    y.onload = function() {
        console.log(y.response);
    };
    y.send();

}

这是我尝试编辑（PUT）新单元格的代码（给我“400 - 错误请求”）：

function add_title(message, token) {

    url = 'https://spreadsheets.google.com/feeds/cells/1NE8g7kyk-Z6Sci9_w6mdY2KV8542a3TJd9lIbucHZiU/default/private/full/cell?access_token=' + token;

    function constructAtomXML(foo){
        var atom = ["<?xml version='1.0' encoding='UTF-8'?>",
            '<entry xmlns="http://www.w3.org/2005/Atom" xmlns:gs="http://schemas.google.com/spreadsheets/2006">',
            '<id>https://spreadsheets.google.com/feeds/cells/1NE8g7kyk-Z6Sci9_w6mdY2KV8542a3TJd9lIbucHZiU/default/private/full/R2C4</id>',
            '<link rel="edit" type="application/atom+xml" href="https://spreadsheets.google.com/feeds/cells/1NE8g7kyk-Z6Sci9_w6mdY2KV8542a3TJd9lIbucHZiU/default/private/full/R2C4"/>',
            '<gs:cell row="2" col="4" inputValue="',foo,'"/>',
            '</entry>'].join('');
        return atom;
    };

    var params = constructAtomXML(message);

    var z = new XMLHttpRequest();
    z.open("PUT", url);
    z.setRequestHeader("Content-type", "application/atom+xml");
    z.setRequestHeader("GData-Version", "3.0");
    z.send(params);

}

在评论的帮助下，我终于明白了：我必须将 OAuth 和 If-Match 添加到请求的标题中。

最终代码应如下所示：

function add_title(token, message) {

    url = 'https://spreadsheets.google.com/feeds/cells/1NE8g7kyk-Z6Sci9_w6mdY2KV8542a3TJd9lIbucHZiU/default/private/basic/R2C4?access_token=' + token;

    function constructAtomXML(foo){
        var atom = ["<?xml version='1.0' encoding='UTF-8'?>",
            '<entry xmlns="http://www.w3.org/2005/Atom" xmlns:gs="http://schemas.google.com/spreadsheets/2006">',
            '<id>https://spreadsheets.google.com/feeds/cells/key/private/basic/R2C4</id>',
            '<link rel="edit" type="application/atom+xml" href="https://spreadsheets.google.com/feeds/cells/key/default/private/basic/R2C4"/>',
            '<gs:cell row="2" col="4" inputValue="' + foo + '"/>',
            '</entry>'].join('');
        return atom;
    };

    var params = constructAtomXML(message);

    var z = new XMLHttpRequest();
    z.open("PUT", url);
    z.setRequestHeader("Content-type", "application/atom+xml");
    z.setRequestHeader("GData-Version", "3.0");
    z.setRequestHeader("Authorization", "GoogleLogin auth=" + token);
    z.setRequestHeader("If-Match", "*");
    z.send(params);

}
