Angularjs + GAE + 端点

Question

我正在尝试将 angularjs 与 google 应用引擎和端点一起使用。我有一个带有小 API 的小型测试应用程序，我正在使用它来使用 angular 和带有 GAE 的端点。 “用户”输入文本并单击“提交”以让条目返回结束。当我从 google 的应用引擎平台执行它时它有效，但我正在努力在客户端实现它。非常感谢任何帮助。

我在你的代码中没有看到你实际调用了你的端点方法。

你必须有这样的东西：

gapi.client.cv.about(message).execute(function(resp) {
                    if (!resp.code) {
                        //ok -- do something    
                    } else {
                        console.log(resp.code);
                    }
            });

在你的插入函数中。

更新。从一开始就。首先你需要加载 client.js

               function loadGoogleClient() {
                    var script = document.createElement("script");
                    script.src = "https://apis.google.com/js/client.js?onload=init";
                    document.body.appendChild(script);
                }
                $(function() {
                    loadGoogleClient();
                });

接下来，您需要加载 api：

function init() {

var endpoint = window.location.origin + '/_ah/api'; 
gapi.client.load('cv', 'v1', '', endpoint); //third argument is a callback

}

然后您可以调用 api 的方法。

愚蠢的我忘了导入和使用 ndb。目前，在 angularjs 中，我已经放弃使用 google-client，直到我学会了正确的实现。这是使用 angular 的 ngResource 依赖项的 "non-google-client" 答案。使用 this github 示例作为指导。

main.py

import webapp2
import settings
import endpoints

from protorpc import message_types
from protorpc import messages
from protorpc import remote

from settings import render_template
from google.appengine.api import users
from google.appengine.ext import ndb

class MainHandler(webapp2.RequestHandler):
    def get(self):
        self.response.write(render_template('base.html'))

#for endpoint
class About(messages.Message):
    about_x = messages.StringField(1)

class AboutModel(ndb.Model):
    about_x = ndb.StringProperty()

@endpoints.api(name='cv', version='v1', description='yup yup yup')
class CvApi(remote.Service):

    @endpoints.method(
        About, 
        About,
        name='about.insert',
        path='about',
        http_method='POST')

    def insert_text(self, request):
        AboutModel(about_x=request.about_x).put()
        return request


api = endpoints.api_server([CvApi])

app = webapp2.WSGIApplication([
    ('/', MainHandler),

], debug=True)

base.html

<div class="container">
    <div id="myCtrl" ng-controller="myCtrl" >
        <form ng-submit="insert()">
            <div><h2>Grilla</h2></div>
            <div><textarea name="texto" ng-model="info"></textarea></div>
            <div><input id="post_this" type="submit" class="btn btn-small" value="Submit"></div>
        </form>
    </div>
</div>

controller.js

var app = angular.module('colinmk', ['ngResource']);

app.config(['$interpolateProvider', function($interpolateProvider) {
  $interpolateProvider.startSymbol('<<');
  $interpolateProvider.endSymbol('>>');
}]);

app.factory('apiResource', function($resource){
    var apiResource = $resource('/_ah/api/cv/v1/about', {
      save:   {method:'POST'}
      // query: {method: 'GET', isArray: false},
      // update: {method: 'PUT'}
    });
    return apiResource;
})

app.controller('myCtrl', ['$scope', 'apiResource',

  function($scope, apiResource) {

    $scope.insert = function() {
      $scope.about = [];
      var r = new apiResource();
      r.about_x = $scope.info;
      r.$save();
      $scope.about.push(r);
      $scope.info = '';
      console.log(r);
    };

}]);
