Today, the editor will show you what the usage of flask and curl is. The knowledge points in the article are introduced in great detail. Friends who feel helpful can browse the content of the article with the editor, hoping to help more friends who want to solve this problem to find the answer to the problem. Let's learn more about "what is the use of flask and curl" with the editor.

Basically familiar with the use of flask and curl, so write a program:

_ _ author__ = 'hochikong'from flask import Flask,requestfrom flask.ext.restful import Resource,Api,reqparseapp = Flask (_ _ name__) api = Api (app) todos = {} parser = reqparse.RequestParser () parser.add_argument (' name',type=str,help='get the name') class TodoSimple (Resource): def get (self,todo_id): return {todo_id: todo _ id]} def put (self Todo_id): Todos [Todo _ id] = request.form ['data'] return {todo_id: Todo [Todo _ id]} 201class GetName (Resource): def post (self): args = parser.parse_args () name = {} name ['ac'] = args [' name'] return name # args = parser.parse_args () # name = args ['name'] # return nameapi.add_resource (TodoSimple,'/') api.add_resource (GetName '/ getname') if _ _ name__ = =' _ main__': app.run ()

Pay attention to the comments in the code. When using reqparse, if you write according to the comments, the following questions will appear:

Hochikong@hochikong-P41T-D3:~$ curl http://localhost:5000/getname-d "name=hochikong"-X POST-v * Hostname was NOT found in DNS cache* Trying 127.0.0.1. * Connected to localhost (127.0.0.1) port 5000 (# 0) > POST / getname HTTP/1.1 > User-Agent: curl/7.35.0 > Host: localhost:5000 > Accept: * / * > Content-Length: 14 > Content-Type: application/x-www-form-urlencoded > * upload completely sent off: 14 out of 14 bytes* HTTP 1.0 Assume close after body < HTTP/1.0 200 OK < Content-Type: application/json < Content-Length: 11 < Server: Werkzeug/0.10.1 Python/2.7.6 < Date: Sat, 21 Mar 2015 15:00:18 GMT < * Closing connection 0

Although it is 200, no data is returned.

I think the output of args ['name'] is indeed a string, but the response of flask-RESTful should be:

Content-Type: application/json

There is no way to format a single string in json format.

But once put in the python dictionary, the result of return is a legitimate json output.

I guessed wow:)
