javascript - 不允许 Django + Angular 方法 PUT 和 POST

Question

我用 Django/Django-Rest 和 AngularJS 1.4.9 重构了一个项目。我的所有 GET 请求都工作正常，但 PUT 和 POST 请求却不能。我收到“405(不允许使用方法)”错误。

我所有的 http 请求都是 Ajax 并且工作正常，但是我现在更改为 $http 并遇到了这个麻烦。怎么了？

app.js

'use strict';
angular.module('myapp', [], function($interpolateProvider, $httpProvider) {
    $interpolateProvider.startSymbol('{[{');
    $interpolateProvider.endSymbol('}]}');
    $httpProvider.defaults.xsrfCookieName = 'jxcsrf';
    $httpProvider.defaults.xsrfHeaderName = 'X-CSRFToken';
}).run(function($http) {
    $http.defaults.headers.common['Content-Type'] = "application/json";
});

更新显示 django View (但我认为不是 django 问题，因为使用了 ajax)

这是标题。

尝试使用 django Rest 框架的通用 View 之一:

http://www.django-rest-framework.org/api-guide/generic-views/

例如，如果您想接受 get 和 put，请使用 RetrieveUpdateAPIView:

from rest_framework import generics

class MusicAction(generics.RetrieveUpdateAPIView):
    #code...
