这是我要实现的代码：-

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()

我可以在 localhost:8888/query 上查询 solr 服务器，但是在我尝试发布数据的 localhost:8888 上，我从 solr 得到以下响应：-

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

数据未发布到 solr 服务器。

有什么建议么 ？？

该代码不包含commitWithin标题中的信息。该参数以毫秒为单位。只有在提交之后，数据才可用于从 Solr 进行搜索。以下可以作为 POST 数据到 solr 的示例。将 JSON 标头连同commitWithin时间和数据作为 JSON 字符串添加到data参数

requests.post("http://localhost:8983/solr/collection1/update?wt=json", headers={"Content-Type":"application/json"}, data='{"add":{ "doc":{"id" : 14, "log_type" : "debug", "log_text" : "A transaction of debug from Kimy"},"boost":1.0,"overwrite":true, "commitWithin": 1000}}')

回复 ：

{"responseHeader":{"status":0,"QTime":128}}
