python-2.7 – 无法使用python和请求发布到solr服务器

import requests
import tornado.ioloop
import tornado.web
import tornado.autoreload
import json

class MainHandler(tornado.web.RequestHandler):
        def get(self):
            payload = [{"id" : "978-0641723445","cat" : ["book","hardcover"],"name" : "The Lightning Thief","author" : "Rick Riordan","series_t" : "Percy Jackson  Olympians","sequence_i" : 1,"genre_s" : "fantasy","inStock" : True,"price" : 12.50,"pages_i" : 384}]
            url = 'http://localhost:8983/solr/update/json'
            headers = {'content-type' : 'application/json'}
            # files = {'file': ('books.json',open('books.json','rb'))}
            timeline = requests.post(url,data = json.dumps(payload),headers = headers)
            self.write(timeline.text)
class QueryHandler(tornado.web.RequestHandler):
        def get(self):
            # timeline = requests.get('http://localhost:8983/solr/collection1/select?q=a&wt=json&indent=true')
            payload = {'q' : 'a','wt' : 'json','indent' : True}
            timeline = requests.get('http://localhost:8983/solr/collection1/select',params = payload)
            self.write(timeline.json())
application = tornado.web.Application([
    (r"/",MainHandler),(r"/query",QueryHandler)
])

if __name__ == "__main__":
    application.listen(8888)
    io_loop = tornado.ioloop.IOLoop.instance()
    tornado.autoreload.start(io_loop)
    io_loop.start()

我能够在localhost：8888 / query上查询solr服务器
但是在localhost：8888我试图发布数据,我从solr得到这个回复： –

{
responseHeader: {
status: 0,QTime: 46
}
}

数据未发布到solr服务器.

有什么建议 ？？
