Python

Question

我一直在使用代码 python 访问这种 url https://api.elsevier.com/analytics/scival/institution/metrics?metricTypes=ScholarlyOutput&institutionIds=508175%2C508076&yearRange=5yrs&includeSelfCitations=true&byYear=true&includedDocs=AllPublicationTypes&journalImpactType=CiteScore&showAsFieldWeighted=false&apiKey=7f59af901d2d86f78a1fd60c1bf9426a

这是 public json url Elsevier Developer Portal

我一直在使用的小代码是这样的：

import requests
import json

url = "https://api.elsevier.com/analytics/scival/institution/metrics?metricTypes=ScholarlyOutput&institutionIds=508175%2C508076&yearRange=5yrs&includeSelfCitations=true&byYear=true&includedDocs=AllPublicationTypes&journalImpactType=CiteScore&showAsFieldWeighted=false&apiKey=7f59af901d2d86f78a1fd60c1bf9426a"

with requests.Session() as s:
    data = s.get(url).json()

一切正常，直到今天我的项目在执行此代码时出错，如果我只运行 s.get(url).text 然后我收到以下消息 'Request not authorized. Please specify a valid API key or HMAC signature.' 我不得不说我什至有自己的 api_key 和 access_token，但即使使用它们我也得到相同的信息。

所以，我需要一些帮助来设法提取数据，因为数据仍在 link https://api.elsevier.com/analytics/scival/institution/metrics?metricTypes=ScholarlyOutput&institutionIds=508175%2C508076&yearRange=5yrs&includeSelfCitations=true&byYear=true&includedDocs=AllPublicationTypes&journalImpactType=CiteScore&showAsFieldWeighted=false&apiKey=7f59af901d2d86f78a1fd60c1bf9426a 中（只是 google 并且会看到它）。希望一些指导来做到这一点，因为直到昨天还没有错误。

Answer 1

我已经检查了文档，您在请求中缺少 header。

以下代码有效。

import requests

url = "https://api.elsevier.com/analytics/scival/institution/metrics?metricTypes=ScholarlyOutput&institutionIds=508175%2C508076&yearRange=5yrs&includeSelfCitations=true&byYear=true&includedDocs=AllPublicationTypes&journalImpactType=CiteScore&showAsFieldWeighted=false&apiKey=7f59af901d2d86f78a1fd60c1bf9426a"

payload={}
headers = {
  'Accept': 'application/json'
}

response = requests.request("GET", url, headers=headers, data=payload)

print(response.text)

Python - 请求未通过使用请求和 json 授权

Python - Request not authorized by using requests and json

url

json

request
