Flask-Restful API和JSON问题中的Unicode

Question

我遇到了与Flask-Restful API服务器的ajax请求中的unicode相关的奇怪问题。 问题仅出现在一台计算机上，而不是另一台计算机上。

我有一个宁静的课。 您可能会注意到字符字段设置为unicode。

class PostListApi(Resource):
def __init__(self):
        self.reqparse = reqparse.RequestParser()
        self.reqparse.add_argument('body', type = unicode, required = True, help = 'No description provided', location = 'json')
        self.reqparse.add_argument('longitude', type = float, required = False, help = 'Unknown address', location = 'json')
        self.reqparse.add_argument('latitude', type = float, required = False, help = 'Unknown address', location = 'json')
        self.reqparse.add_argument('address', type = unicode, required = True, help = 'No address specified', location = 'json')
        self.reqparse.add_argument('scheduled', type = str, required = True, help = 'Not scheduled correctly', location = 'json')
        super(PostListApi, self).__init__()

我的问题是，当我在BODY中发送带拉丁字符的ajax请求时，服务器会回复400错误。

Request URL:

但是当数据采用cyrilic字母表时，服务器会正​​确管理请求。

使用jquery的ajax方法完成请求生成

function ajaxRequest(uri, method, data){
    var request = {
                url: uri,
                type: method,
                contentType: "application/json; charset=utf-8",
                accepts: "application/json",
                cache: false,
                dataType: 'json',
                //data: data != null?((method == 'GET') ? $.param(data): utf8_encode(JSON.stringify(data))):null,
                data: data != null?((method == 'GET') ? $.param(data): JSON.stringify(data)):null,
                beforeSend: function (xhr) {},
                error: function(jqXHR) {
                    console.log("ajax error " + jqXHR.status);
                }
            };
    return $.ajax(request);

你以前遇到过类似的问题吗？ 怎么解决这个问题？ 我想在发送到服务器之前，拉丁字符也必须编码为unicode。 我怎么能强制jquery将所有内容编码为unicode？

提前致谢！

我使用跟随代码，我没有这个问题和输出问题

import sys
reload(sys)
sys.setdefaultencoding('utf-8')
from flask import Flask
from flask.ext.restful import Api
from flask.ext.restful.representations.json import output_json
output_json.func_globals['settings'] = {'ensure_ascii': False, 'encoding': 'utf8'}
app = Flask(__name__)
api = Api(app)
...
