Flask-Restful API和JSON問題中的Unicode

Question

我遇到了與Flask-Restful API服務器的ajax請求中的unicode相關的奇怪問題。 問題僅出現在一台計算機上，而不是另一台計算機上。

我有一個寧靜的課。 您可能會注意到字符字段設置為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__()

我的問題是，當我在BODY中發送帶拉丁字符的ajax請求時，服務器會回復400錯誤。

Request URL:
Request Method:POST
Status Code:400 BAD REQUEST

但是當數據采用cyrilic字母表時，服務器會正​​確管理請求。

使用jquery的ajax方法完成請求生成

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);

你以前遇到過類似的問題嗎？ 怎么解決這個問題？ 我想在發送到服務器之前，拉丁字符也必須編碼為unicode。 我怎么能強制jquery將所有內容編碼為unicode？

提前致謝！

我使用跟隨代碼，我沒有這個問題和輸出問題

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)
...
