Question

我执行了这段代码以连接最常见的api-

    import requests
    response = requests.get("http://api.open-notify.org/iss-now.json")
    print(response.status_code)

但它显示此错误-

    runfile('C:/Users/sanchit.joshi/use case of unassigned tickets/Api try 
    out.py', wdir='C:/Users/sanchit.joshi/use case of unassigned tickets')
    Traceback (most recent call last):

    File "<ipython-input-17-39bcdc5917ae>", line 1, in <module>
    runfile('C:/Users/sanchit.joshi/use case of unassigned tickets/Api try

    File "C:\ProgramData\Anaconda3\lib\site- 
    packages\spyder_kernels\customize\spydercustomize.py", line 668, in

    File "C:\ProgramData\Anaconda3\lib\site-

    File "C:/Users/sanchit.joshi/use case of unassigned tickets/Api try

    response = requests.get("http://api.open-notify.org/iss-now.json")

    return session.request(method=method, url=url, **kwargs)

    line 512, in request
    resp = self.send(prep, **send_kwargs)

    File "C:\ProgramData\Anaconda3\lib\site-packages\requests\sessions.py", 
    line 622, in send
    r = adapter.send(request, **kwargs)

    File "C:\ProgramData\Anaconda3\lib\site-packages\requests\adapters.py", 
    line 513, in send
    raise ConnectionError(e, request=request)

    ConnectionError: HTTPConnectionPool(host='api.open-notify.org', 
    port=80): Max retries exceeded with url: /iss-now.json (Caused by 
    NewConnectionError('<urllib3.connection.HTTPConnection object at 
    0x000001E8E5BCBE80>: Failed to establish a new connection: [Errno 11002] 
    getaddrinfo failed'))

我尝试更改最大重试值，但不起作用。更令人沮丧的是，这是连接到api的最简单代码。任何帮助表示赞赏。

Answer 1

使用JSON和urllib.request库

import json
import urllib.request

file = urllib.request.urlopen("http://api.open-notify.org/iss-now.json")
data = json.loads(file.read())
print(data)

产生

{'message': 'success', 'timestamp': 1541059187, 'iss_position': {'longitude': '13.6813', 'latitude': '47.8641'}}

您的代码没有错，该代码应该可以工作。

您遇到代理问题。如果您在Windows上，则可以通过以下步骤将URL添加到代理例外中：Internet浏览器中的设置菜单，然后依次选择Internet选项，连接，局域网设置，并将URL添加到例外中。在公司环境或您的学校中，管理员通常会把您置于代理之后。

或者，您可以使用this Q/A在请求中设置代理
