ExpressJS AngularJS POST [英] ExpressJS AngularJS POST
问题描述
我正在学习AngularJS,我想知道如何使用ExpressJS正确地连接Node。
这是我的控制器:
app.controller('view1Ctrl',function($ scope,$ http){
$ scope.sub = function ){
console.log(desc);
$ http.post('/ view1',desc)
then(function(response){
console.log发布成功);
})。catch(function(response){
console.error(error in posting);
})
}
} );
这是我的server.js:
app.post('/ view1',function(req,res){
console.log(res.desc);
res.end();
});
我没有使用body-parser。当我在控制器中使用一个函数时,我不知道如何使用body-parser从html中获取表单值。在使用body-parser时单击提交时,从html中获取的值是否从我将表单值作为参数传递的函数获取值。请告诉我如何完成。
编辑:这是我的html:
<形式>
< input type =textng-model =descplaceholder =输入desc/>
< button class =btn btn-primaryng-click =sub(desc)> Submit< / button>
< / form>

full server.js code: / p>
var express = require('express'),
http = require('http'),
path = require('path'),
bodyParser = require('body-parser');
var app = express();
app.set('port',3000);
app.use(express.static(path.normalize(__ dirname +'/')));
app.use(bodyParser.json()); // for parsing application / json
app.use(bodyParser.urlencoded({extended:true})); // for parsing application / x-www-form-urlencoded
app.get('/ main',function(req,res){
var name ='MyNameFromServer';
res.send(name);
});
app.post('/ view1',function(req,res){
console.log(res.body.desc);
res.end();
});
http.createServer(app).listen(app.get('port'),function(){
console.log('Express server listening on port'+ app.get 'port'));
});

编辑的控制器app.js < ($ view,$ http){
$ scope.sub = function( ){
console.log($ scope.formData);
$ http.post('/ view1',$ scope.formData)
success(function(data){
console.log(posted successfully);
})。error(function(data){
console.error(error in posting);
})
};
});
Node.js(Express )可以将您的表单中的每个数据都从一个名为 req.body
的对象中获取,所以如果你有一个 $ scope
对象定义您可以直接注入的表单数据,以便在req.body上复制相同的属性:
Angular:
app.controller('view1Ctrl',function($ scope,$ http){
$ scope.sub = function(){
$ http .post('/ view1',$ scope.formData)
then(function(response){
console.log(posted successfully);
})catch响应){
console.error(posting中的错误);
})
}
});
HTML:
code><形式>
< input type =textng-model =formData.descplaceholder =输入desc/>
< input type =textng-model =formData.titleplaceholder =输入标题/>
< button type =submitclass =btn btn-primaryng-click =sub()> Submit< / button>
< / form>
现在,当您通过 $ http.post('/ view1) ,$ scope.formData)
您将获得相同的对象,例如:
app.post ('/ view1',function(req,res){
console.log(req.body.desc);
res.end();
});
相反,点击提交按钮,您还可以使用 ng-submit
在表单元素中,如下所示:
< form ng-submit =sub ()>
I'm learning AngularJS and I want to know how to correctly wire it with Node with ExpressJS.
This is my controller:
app.controller('view1Ctrl', function($scope, $http) {
$scope.sub = function(desc) {
console.log(desc);
$http.post('/view1', desc).
then(function(response) {
console.log("posted successfully");
}).catch(function(response) {
console.error("error in posting");
})
}
});
And this is my server.js:
app.post('/view1', function(req, res) {
console.log(res.desc);
res.end();
});
I have not used body-parser. I don't get how body-parser is used to get the form values from the html when I am using a function in controller. Does the values got from the html on clicking submit when using body-parser or does the values are got from the function on which I am passing the form values as arguments. Please tell me how it is done .
EDIT: this is my html:
<form>
<input type="text" ng-model="desc" placeholder="Enter desc" />
<button class="btn btn-primary" ng-click="sub(desc)">Submit</button>
</form>
EDIT 2: full server.js code:
var express = require('express'),
http = require('http'),
path = require('path'),
bodyParser= require('body-parser');
var app = express();
app.set('port', 3000);
app.use(express.static(path.normalize(__dirname + '/')));
app.use(bodyParser.json()); // for parsing application/json
app.use(bodyParser.urlencoded({ extended: true })); // for parsing application/x-www-form-urlencoded
app.get('/main', function(req, res) {
var name = 'MyNameFromServer';
res.send(name);
});
app.post('/view1', function(req, res) {
console.log(res.body.desc);
res.end();
});
http.createServer(app).listen(app.get('port'), function() {
console.log('Express server listening on port ' + app.get('port'));
});
EDIT 3: Edited Controller app.js
app.controller('view1Ctrl', function($scope, $http) {
$scope.sub = function() {
console.log($scope.formData);
$http.post('/view1', $scope.formData).
success(function(data) {
console.log("posted successfully");
}).error(function(data) {
console.error("error in posting");
})
};
});
The body-parser module for Node.js (Express) can get every data from your form post into a single object called req.body
, so if you have a $scope
object to define your form data you can inject directly that to have the same properties copied on req.body:
Angular:
app.controller('view1Ctrl', function($scope, $http) {
$scope.sub = function() {
$http.post('/view1',$scope.formData).
then(function(response) {
console.log("posted successfully");
}).catch(function(response) {
console.error("error in posting");
})
}
});
HTML:
<form>
<input type="text" ng-model="formData.desc" placeholder="Enter desc" />
<input type="text" ng-model="formData.title" placeholder="Enter title" />
<button type="submit" class="btn btn-primary" ng-click="sub()">Submit</button>
</form>
Now when you submit it via $http.post('/view1', $scope.formData)
you will get the same object, for example:
app.post('/view1', function(req, res) {
console.log(req.body.desc);
res.end();
});
Instead having an ng-click on the submit button, you could also use ng-submit
in the form element like this:
<form ng-submit="sub()">
