我正在尝试使用TM1 REST API和Python请求运行get请求，但是收到ConnectionResetError / MaxRetryError / ProxyError。这是我的代码：
headers = {'Accept' : 'application/json; charset=utf-8',
'Content-Type': 'text/plain; charset=utf-8'
}
login = b64encode(str.encode("{}:{}:{}".format(user, password, namespace))).decode("ascii")
headers['Authorization'] = 'CAMNamespace {}'.format(login)
s = requests.Session()
r = s.get(url+query, headers=headers, proxies=urllib.request.getproxies())
我已尝试使用代理身份验证/无身份验证/无代理的get请求但我得到相同的3个错误。
作为参考，相同的网址是https，适用于JavaScript / jQuery：
function updateTable(){
$.ajax({
async:false,
headers: {
'Accept' : 'application/json; charset=utf-8',
'Content-Type': 'text/plain; charset=utf-8',
'Authorization' : 'CAMNamespace ' + btoa('username' + ':' + 'password' + ':' + 'namespace')
},
url: 'url_is_here',
success: function(data){data_is_here}
}
这是TraceBack：

答案 0 :(得分：0)
有几个人帮我解决了我的问题。我在环境变量中设置的http和https代理导致了这个问题。我删除了它们/重新启动/然后能够查询api。
