【问题描述】：
我正在尝试使用 Scopus API 来检索由 scopus 分配给作者的唯一作者标识符号。在某些情况下，一个名字会产生多个作者 ID。我的麻烦在于读取 json 格式，以便我可以解析出 'dc:identifiers'
这是我的代码：
import requests
import json
url = "http://api.elsevier.com/content/search/author"
querystring = {"apiKey":"xxxxxxxxxxxxx","query":["AUTHLASTNAME(Volaire)","AUTHFIRST(F)"]}
headers = {
'cache-control': "no-cache",
'postman-token': "5c0df5ad-2645-8e88-0f8a-10795757b4ec"
}
response = requests.request("GET", url, headers=headers, params=querystring)
results = response.json()
然后我得到以下输出：
{
"search-results": {
"opensearch:totalResults": "3",
"opensearch:startIndex": "0",
"opensearch:itemsPerPage": "3",
"opensearch:Query": {

我需要做的是解析这个，以便获得被拉起的“dc:identifiers”。在这种情况下，有 3 个。
理想情况下，我想把它放到我有的表中 AUTHLASTNAME / AUTHFIRST / DCIDENTIFER（列）
任何建议表示赞赏。
【问题讨论】：
-
发布的代码与问题无关（关于处理它产生的数据）；这是正确的吗？
-
@ScottHunter：没错，只是它告诉你我是如何得到 json 输出的。
-
您如何获得数据无关紧要；并且您发布的输出不完整。
