flask使用url_open与redirect实现endpoint带参数的跳转

Search部分

from flask_restful import Resource, reqparse
from flask import url_for, redirect

class SearchAPI(Resource):
    def __init__(self):
        self.parser = reqparse.RequestParser()
        self.parser.add_argument('q', type=str, help='query info', ignore=False)
        super(SearchAPI, self).__init__()

    def get(self):
        args = self.parser.parse_args()
        info = args.get('q')
        # 查询的info为asset_id，所以通过url_for定下跳转的url(endpoint为asset，所有对应参数为asset_id, page, tag)
        response = redirect(url_for('asset', asset_id=info, page=2, tag='balances'))
        print type(response)
        return response

Asset部分

from flask_restful import Resource, reqparse, abort
from manager import AssetManager

# 由url部分得知endpoint为'asset'
# (blockmeta.asset.api.AssetAPI, ('/api/asset/<string:asset_id>',), {'endpoint': 'asset'})
class AssetAPI(Resource):
    def __init__(self):
        self.manager = AssetManager()
        self.parser = reqparse.RequestParser()
        self.parser.add_argument('page', type=int, help='page number of txs/balances')
        self.parser.add_argument('tag', type=str, help='txs/balances')
    # 传入参数有三个asset_id表现在url上，而page和tag表现在?以后
    def get(self, asset_id):
        asset_id.strip().lower()
        args = self.parser.parse_args()
        page = args.get('page')
        tag = args.get('tag')
        page = 1 if page is None or not isinstance(page, int) or page <= 0 else page
        tag = 'txs' if tag is None or not isinstance(tag, str) or tag not in ['txs', 'balances'] else tag
        result = self.manager.handle_asset(asset_id, page, tag)
        if len(result) == 0:
            abort(404, message="asset not found")
        return result

url部分

# -*- coding: utf-8 -*-
from flask_restful import Api
import blockmeta.asset.api

# modules = [(handle, urls, args)]
# endpoint 为 'asset'
MODULES = [
    (blockmeta.asset.api.AssetAPI, ('/api/asset/<string:asset_id>',), {'endpoint': 'asset'}),
]

def register_api(app):
    api = Api(app)
    for handle, urls, args in MODULES:
        api.add_resource(handle, *urls, **args)

浏览器自动跳转至
