AngularJS的POST请求的空？ [英] AngularJS POSTs empty requests?

问题描述

我在AngularJS一个新手，当我试图与AngularJS一个POST请求，并帖子没有与它的参数我所面临的问题。我用西纳特拉作为一个RESTful接口。

I'm a newbie in AngularJS and I've faced an issue when I try to make a POST request with AngularJS and it POSTs no parameters with it. I use Sinatra as a RESTful interface.

这是我的西纳特拉后端的外观：

That's how my Sinatra backend looks:

post '/layer/:layer_id' do
  @layer = PageLayer.where(id: params[:layer_id]).first
  @layer.content = params[:content]
  @layer.save
end

如果尝试用邮差Chrome扩展到邮政 - 它的作品！西纳特拉妥善保存的内容。所以我敢肯定，后端的工作，因为它应该。

If try to POST with Postman chrome extension - it works! Sinatra saves the content properly. So I'm sure that the backend works as it should.

这是我的角度测试code的外观：

That's how my angular test code looks:

TestCtrl = ($scope, $routeParams, $http, $resource) ->
    $scope.layer = []

    Layer = $resource('/layer/:id', {id:'@id'})

$scope.layer = Layer.get {id: $routeParams.layerId}, ->
    console.log "Got you!"

$scope.saveContent = ->
    $scope.layer.$save()
    console.log "Saved!"

angular.module('appDirectives', []).directive "test", ->
    return (scope, element, attrs) ->
        element.bind "blur", ->
            console.log("blur!")
            scope.saveContent()

和HTML的code：

And HTML-code:

<div>Content: {{layer.content}}</div>

<div>
    <form>
        <input type="text" test ng-model="layer.content">
    </form>
</div>

所以，唯一的问题是：怎么了？为什么我能做出正确的请求，与邮递员，但不与angularJS？角返回空的内容，所以西纳特拉将其保存为，每一次。

So, the only question is: What's wrong? Why I can make correct request with Postman but not with angularJS? Angular returns empty "content" so Sinatra saves it as "" every time.

我还附上了一层的结构：

I've also attached a structure of a layer:

g {id: 27245, page_id: 2302, external_id: 26518, original_upload: null…}
content: "dfgdfg"
external_id: 26518
id: 27245
layerNumber: 8
page_id: 2302

我怎样才能登录究竟角的帖子吗？

How can I log what exactly angular POSTs?

推荐答案

好吧，我已经解决了这个问题。不知怎的，西纳特拉没有得到正确的角职位和未自动把它们变成PARAMS。
所以，如果我们手动解析请求 - 它的作品。这样的：

All right, I've solved the issue. Somehow Sinatra was not properly getting POSTs from Angular and was not automatically putting them into params. So if we parse the request manually - it works. Like that:

post '/layer/:layer_id' do
  @updated_layer = JSON.parse(request.body.string)
  @layer = PageLayer.where(id: params[:layer_id]).first
  @layer.content = @updated_layer['content']
  @layer.save 
end
