在后Restangular不设置页眉 [英] Restangular not setting headers on post

问题描述

我试图设置使用restangular一个POST请求头，但该请求被发送以纯文本格式，而不是JSON。
我已阅读文档这里以及一<一href=\"http://stackoverflow.com/questions/21292052/setting-headers-and-http-params-for-a-single-request-in-restangular\">similar问题。
我按照prescribed方法，但都无济于事。

I am trying to set the header for a single post request using restangular but the request is being sent as plain text instead of json. I have read the documentation here as well as a similar question. I have followed the prescribed methods but to no avail.

在服务器端，我用防爆preSS 4.x和使用MongoDB的所谓Moongoose一个ORM通信。

On the server side am using Express 4.x and communicating with Mongodb using an ORM called Moongoose.

服务器端：使用前press.js server.js 4.0

'use strict';

var express = require('express'),
    morgan  = require('morgan'),
    port =process.env.PORT || 3000,
    bodyParser  = require('body-parser'),
    methodOverride = require('method-override'),
    app = express();


app.use(morgan('dev'));             
app.use(bodyParser());              
app.use(methodOverride());          
app.use(express.static(__dirname+"/app"));

require('./config/models');
require('./config/user_ctrl');
require('./config/comt_ctrl');
require('./config/routes')(app);

app.listen(port);   
console.log('Magic happens on port: '+port); 

//Server side: routes.js
var pips = require('./user_ctrl');

module.exports = function(app){

    app.get('/api/pipplez',pips.getPipplez); //Gets all users in collection
    app.post('/api/pipplez/wan',pips.getPipplezById); //Gets the specified user

    app.all('/api/*', function(req, res) {
        res.send(404);
    });

    app.get('/*', function(req, res){
       res.send('index.html'); 
    });
};

在客户端我有这个。

客户端：配置后app.js

Client side: app.js after config

.factory('userServ',function(Restangular){

  var ol = Restangular.withConfig(function(conf){
    conf.setBaseUrl('/api/')
  });

  var an = Restangular.withConfig(function(conf){
    conf.setBaseUrl('/api/users/')
  });
    return{
          oldem: ol.one('users').getList(),
          wandem: an.one('one')
    }
});

客户端：userCtr.js

Client side: userCtr.js

'use strict';

ting.controller('userCtrl', function($scope, userServ){

    $scope.pip = {
       name: ''
    };

    $scope.getOlPips = function(){

    userServ.oldem.then(function(rez){

        if(rez!=='null'){
            $scope.dem = rez;
            console.log($scope.dem);
        }
    }, function(err){
        console.log('Error!!!\n', err );
    })  
};

$scope.getWanPip = function(pip){
    //console.log(pip);
    RestServ.wandem.post(pip, {}, {'Content-Type':'application/json'}).then(function(res){
        console.log(res)      
    }, function(err){
        console.log('Error!!!\n', err);
    })
};

$scope.getOlUzas();    
});

在HTML的一部分

part of the html

<form>
    <input ng-model='pip.unm' maxlength= '20' placeholder='Search for user...'>
    <button class="btn btn-primary" ng-click = 'getWanPip(pip)'>Find</button>
</form>

我已经广泛使用后端<一个href=\"https://chrome.google.com/webstore/detail/postman-rest-client/fdmmgilgnpjigdojojpjoooidkmcomcm?hl=en\"相对=nofollow>邮递员。后端运行正常。该应用程序能够从数据库中获取所有记录但是当我做POST请求，我收到了404，因为请求的格式为纯文本，而不是JSON发送。我怎样才能得到这个工作？

I have extensively tested the back end using postman. The back end is functioning. The application is able to get all the records from the database however when I make the post request I get a 404 because the format of the request is sent as plain text instead of json. How can I get this to work?

推荐答案

在网络上摸索后，我发现restangular默认表单数据发送到服务器的JSON格式。笔者从铬的开发者工具误导。为了disect http请求我建议小提琴手
如果一个人想格式化restangular头发送从形式提出的请求，你可以做到以下几点：

After groping around the web, I found that restangular sends form data to the server in json format by default. I was misguided by the developer tools from chrome. In order to disect http requests I recommend fiddler If one wants to format the header in restangular being sent as a request from the form you can do the following:

//From the previous example....
//Assuming restangular did not not send form data in json format by default

    $scope.getWanPip = function(pip){

        RestServ.wandem.post(pip, {},{}, {'Content-Type':'application/json'}).then(function(res){
            console.log(res)      
        }, function(err){
            console.log('Error!!!\n', err);
        })

请注意两个空的大括号，而不是一...
我仍然不能执行职务，但，这是因为数据正在而不是单独发送的URL的一部分。这就需要另外一个问题...

Note the two empty curly braces instead of one... I can't still perform the post but this is because the data is being sent as part of the url instead of separately. This calls for another question...
