我正在尝试使用 python SimpleHTTPServer 构建一个简单的 REST 服务器。我在从帖子消息中读取数据时遇到问题。如果我做得对，请告诉我。
from SimpleHTTPServer import SimpleHTTPRequestHandler
import SocketServer
import simplejson
class S(SimpleHTTPRequestHandler):
def _set_headers(self):
self.send_response(200)
self.send_header('Content-type', 'text/html')
self.end_headers()
def do_GET(self):
print "got get request %s" % (self.path)
if self.path == '/':
self.path = '/index.html'
return SimpleHTTPRequestHandler.do_GET(self)
def do_POST(self):
print "got post!!"
content_len = int(self.headers.getheader('content-length', 0))
post_body = self.rfile.read(content_len)
test_data = simplejson.loads(post_body)
print "post_body(%s)" % (test_data)
return SimpleHTTPRequestHandler.do_POST(self)
def run(handler_class=S, port=80):
httpd = SocketServer.TCPServer(("", port), handler_class)
print 'Starting httpd...'
httpd.serve_forever()
index.html 文件
<html>
<title>JSON TEST PAGE</title>
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript">
JSONTest = function() {
var resultDiv = $("#resultDivContainer");
$.ajax({
url: "http://128.107.138.51:8080",
type: "POST",
data: {txt1: $("#json_text").val()},
dataType: "json",
success: function (result) {
switch (result) {
case true:
processResponse(result);
break;
default:
resultDiv.html(result);
}
},
error: function (xhr, ajaxOptions, thrownError) {
alert(xhr.status);
alert(thrownError);
}
});
};
</script>
</head>
<body>
<h1>My Web Page</h1>
<div id="resultDivContainer"></div>
<form>
<textarea name="json_text" id="json_text" rows="50" cols="80">
[{"resources": {"dut": "any_ts", "endpoint1": "endpoint", "endpoint2": "endpoint"}},
{"action": "create_conference", "serverName": "dut", "confName": "GURU_TEST"}]
</textarea>
<button type="button" onclick="JSONTest()">Generate Test</button>
</form>

SimpleJson 无法从 POST 消息中加载 json。我不熟悉网络编码，我什至不确定我所做的是否适合创建一个简单的 REST API 服务器。 我感谢您的帮助。

感谢 matthewatabet 提出 klein 的想法。我想出了一种使用 BaseHTTPHandler 来实现它的方法。下面的代码。
from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer
import SocketServer
import simplejson
import random
class S(BaseHTTPRequestHandler):
def _set_headers(self):
self.send_response(200)
self.send_header('Content-type', 'text/html')
self.end_headers()
def do_GET(self):
self._set_headers()
f = open("index.html", "r")
self.wfile.write(f.read())
def do_HEAD(self):
self._set_headers()
def do_POST(self):
self._set_headers()
print "in post method"
self.data_string = self.rfile.read(int(self.headers['Content-Length']))
self.send_response(200)
self.end_headers()
data = simplejson.loads(self.data_string)
with open("test123456.json", "w") as outfile:
simplejson.dump(data, outfile)
print "{}".format(data)
f = open("for_presen.py")
self.wfile.write(f.read())
return
def run(server_class=HTTPServer, handler_class=S, port=80):
server_address = ('', port)
httpd = server_class(server_address, handler_class)
print 'Starting httpd...'
httpd.serve_forever()
if __name__ == "__main__":
from sys import argv
if len(argv) == 2:
run(port=int(argv[1]))
else:
run()
以及对应的html页面
<form action="/profile/index/sendmessage" method="post" enctype="application/x-www-form-urlencoded">
<div class="upload_form">
<dt id="message-label"><label class="optional" for="message">Enter Message</label></dt>
<dd id="message-element">
<textarea cols="80" rows="50" id="message" name="message">
[{"resources": {"dut": "any_ts", "endpoint1": "multistream_endpoint", "endpoint2": "multistream_endpoint"}},
{"action": "create_conference", "serverName": "dut", "conferenceName": "GURU_SLAVE_TS"},
{"action": "dial_out_ep", "serverName": "dut", "confName": "GURU_SLAVE_TS", "epName": "endpoint1"}
]
</textarea></dd>
<dt id="id-label"> </dt>
<dd id="id-element">

<dt id="send_message-label"> </dt>
<dd id="send_message-element">

</div>
</form>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript">
$("input.sendamessage").click(function(event) {
event.preventDefault();
var message = $('textarea#message').val();
var id = $('input#id').val();
url = "http://128.107.138.51:8080"
var posting = $.post(url, message)
posting.done(function( data ) {
alert(message);
});
});
</script>
关于python - 从 SimpleHTTPServer Post 数据中读取 JSON，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31371166/
