r - 搜索 Scopus 搜索 API 时出错并将结果批量保存到 xml 文件中

Question

我正在尝试使用 rscopus 和从https://github.com/christopherBelter/scopusAPI获得的函数从 Scopus 中提取摘要

我有使用我的大学帐户的 API 密钥，但是在尝试将数据保存为 xml 时，使用：

theXML <- searchByString(string = query, outfile = "testdata.xml")

我收到一个错误：

Error in searchByString(string = query, outfile = "testdata.xml") : Unauthorized (HTTP 401).
    3. stop(http_condition(x, "error", task = task, call = call))
    2. httr::stop_for_status(theURL) at scopusAPI.R#12
    1. searchByString(string = query, outfile = "testdata.xml")

自“：未经授权（HTTP 401）”以来，我的 API 密钥有问题吗？

Answer 1

Have you tried validating your string outside of the script?

The Elsevier Developer Portal would be a good place to try out your string to confirm it works or to refine it so it works
