Python：从本地主机调用另一个本地主机服务器

Question

def jsonCatch(environ,start_response):
     results = requests.get("http://localhost:8055/jsonResponse") 
     start_response('200 OK', [('Content-Type', 'application/json')])
     return results.json()

from wsgiref.simple_server import make_server
httpd = make_server('', 8050, application)
print('Serving on port 8050...')
httpd.serve_forever()

serving on port 8055

def jsonResponse(environ,start_response):
    responseData={}
    responseData['name']="alex"
    responseData['age']="12"
    start_response('200 OK',[('Content-Type', 'application/json')])    
    return json.dumps(responseData)

Edit: Changed https to http and error on server

I am trying to access a localhost server which returns a json response and is used by another localhost server. Can somebody show me an example of it?

Answer 1

I have changed the above code to

n=json.loads(results.text)
start_response('200 OK', [('Content-Type', 'text/plain')])
return n['name'].encode('utf-8')

and it returns me "alex"

Answer 2

尝试在此行上使用http://而不是https:// ： results = requests.get("https://localhost:8055/jsonResponse")
