环境： node， python3.6
使用node.js 的request模块发送 post请求，请求参数放在body中。服务端使用python3 http.server搭建服务。
nodejs 请求
var request = require('request');
var qs = require('querystring')
var xml_data = "<note><to>George</to><from>John</from><heading>Reminder</heading><body>Don't forget the meeting!</body></note>"
var data = qs.stringify({q: xml_data})
request({
url: 'http://127.0.0.1:7700/parse',
method: 'POST',
body: data,
}, function(error, resp, body){
try {
var r = JSON.parse(body)
if (r.returncode == 0) {
console.log("success !");
} else {
console.log("ERROR ", r.message);
}
} catch (e) {
console.log("error");
}
});
发送的请求参数在body中。
python3 server：
import json
import http.server
import socketserver
from urllib.parse import urlparse, parse_qs, unquote
PORT = 7700
class HandleServer(http.server.BaseHTTPRequestHandler):
def do_POST(self):
query = urlparse(self.path)
returncode, msg = 0, "success"
if query.path.strip("/") == urlparse("/parse/").path.strip("/") :
if True:
qdata = self.rfile.read(int(self.headers['content-length'])).decode("utf-8")
params = parse_qs(unquote(qdata))
q = params.get("q", [""])[0]
except Exception as e:
print(e)
returncode, msg = 2000, "ERROR"
else:
returncode, msg = 1000, "url path should be /parse"
self.send_response(200)
self.send_header('Content-type','text/html')
self.end_headers()
output = {"returncode": returncode, "message": msg}
self.wfile.write(json.dumps(output).encode("utf-8"))
handler = HandleServer
with socketserver.TCPServer(("", PORT), handler) as httpd:
print("server starting..", PORT)
httpd.serve_forever()
说明：
对于post中，参数放在请求url后面的，使用 self.path 来获取。
关于读取请求中的body数据： rfile - An io.BufferedIOBase input stream, ready to read from the start of the optional input data.
