我正在尝试从我们正在使用的 API 中提取数据并将其放入 Google 表格中。我从 FastFedora 获得了这段代码（见下面的代码），但不幸的是，这些东西目前无法正常工作或传递凭据。
我目前在 Google 表格中调用它的方式是利用以下命令：
=ImportJSONBasicAuthentication("https://WEBSITE.com/builds/ids?include_shares=true&app_id=*","noInherit,noTruncate,rawHeaders")
在 script.google 中，但它返回“代码 401”错误。任何帮助表示赞赏。我也很乐意回答任何问题。

A library for importing JSON feeds into Google spreadsheets. Functions include:
ImportJSON For use by end users to import a JSON feed from a URL
ImportJSONAdvanced For use by script developers to easily extend the functionality of this library
Future enhancements may include:
- Support for a real XPath like syntax similar to ImportXML for the query parameter
- Support for OAuth authenticated APIs
Or feel free to write these and add on to the library yourself!
------------------------------------------------------------------------------------------------------------------------------------
Changelog:
1.1 Added support for the noHeaders option
1.0 Initial release
*====================================================================================================================================*/
/**
* Imports a JSON feed and returns the results to be inserted into a Google Spreadsheet. The JSON feed is flattened to create
* a two-dimensional array. The first row contains the headers, with each column header indicating the path to that data in
* the JSON feed. The remaining rows contain the data.
*
* By default, data gets transformed so it looks more like a normal data import. Specifically:
*
* - Data from parent JSON elements gets inherited to their child elements, so rows representing child elements contain the values
* of the rows representing their parent elements.
* - Values longer than 256 characters get truncated.
* - Headers have slashes converted to spaces, common prefixes removed and the resulting text converted to title case.
*
* To change this behavior, pass in one of these values in the options parameter:
*
* noInherit: Don't inherit values from parent elements
* noTruncate: Don't truncate values
* rawHeaders: Don't prettify headers
* noHeaders: Don't include headers, only the data
* debugLocation: Prepend each value with the row & column it belongs in
*
* For example:
*
* =ImportJSON("http://gdata.youtube.com/feeds/api/standardfeeds/most_popular?v=2&alt=json", "/feed/entry/title,/feed/entry/content",
* "noInherit,noTruncate,rawHeaders")
*
* @param {url} the URL to a public JSON feed
* @param {query} a comma-separated lists of paths to import. Any path starting with one of these paths gets imported.
* @param {options} a comma-separated list of options that alter processing of the data
*
* @return a two-dimensional array containing the data, with the first row containing headers
* @customfunction

/**
* An advanced version of ImportJSON designed to be easily extended by a script. This version cannot be called from within a
* spreadsheet.
*
* Imports a JSON feed and returns the results to be inserted into a Google Spreadsheet. The JSON feed is flattened to create
* a two-dimensional array. The first row contains the headers, with each column header indicating the path to that data in
* the JSON feed. The remaining rows contain the data.
*
* Use the include and transformation functions to determine what to include in the import and how to transform the data after it is
* imported.
*
* For example:
*
* =ImportJSON("http://gdata.youtube.com/feeds/api/standardfeeds/most_popular?v=2&alt=json",
* "/feed/entry",
* function (query, path) { return path.indexOf(query) == 0; },
* function (data, row, column) { data[row][column] = data[row][column].toString().substr(0, 100); } )
*
* In this example, the import function checks to see if the path to the data being imported starts with the query. The transform
* function takes the data and truncates it. For more robust versions of these functions, see the internal code of this library.
*
* @param {url} the URL to a public JSON feed
* @param {query} the query passed to the include function
* @param {options} a comma-separated list of options that may alter processing of the data
* @param {includeFunc} a function with the signature func(query, path, options) that returns true if the data element at the given path
* should be included or false otherwise.
* @param {transformFunc} a function with the signature func(data, row, column, options) where data is a 2-dimensional array of the data
* and row & column are the current row and column being processed. Any return value is ignored. Note that row 0
* contains the headers for the data, so test for row==0 to process headers only.
*
* @return a two-dimensional array containing the data, with the first row containing headers
