问题描述
我试图从角度到前preSS发布的数据,但是,我eachtime使POST请求我得到这个错误。
选项的http://本地主机/后/净:: ERR_CONNECTION_REFUSED(匿名函数)@ angular.js:11209s @ angular.js:11002克@ angular.js:10712(匿名函数)@ angular.js:15287米$ @的eval angular.js:。16554米$ @消化angular.js:16372米$ @适用angular.js:16662(匿名函数)@ angular.js:24283m.event.dispatch @的jQuery .js文件:// @ 4670r.handle的jquery.js:4338
controller.js:29
和errorCallback响应对象是:
对象{数据:空,状态:-1,配置:对象,状态文本:}
我做了一些调整,在寻找上的其他类似的问题,如添加标题,内容类型等,但没有运气。
什么似乎是这里的问题。
谢谢
Controller.js
word.add =功能(){
的console.log(word.name); $ HTTP({
方法:POST,
网址:的http://本地主机/后/',
数据:word.name,
标题:{内容类型:应用/ JSON'}
})。然后(函数successCallback(响应){
的console.log(响应);
的console.log(成功);
},功能errorCallback(响应){ 的console.log(响应);
的console.log(失败);
});
};
从相关code摘录 app.js
VAR路线=要求('./路线/指数');
app.all('/ *',函数(请求,响应下一个){
response.header(访问控制允许原产地,*);
response.header(访问控制允许的方法,GET,PUT,POST,DELETE');
response.header(访问控制允许报头,X-请求-着,内容类型);
下一个();
});app.use(记录器('开发'));
app.use(bodyParser.json());
app.use(bodyParser.urlen codeD({延长:假}));
app.use('/后,路线);
index.js
VAR前preSS =要求('前preSS');
VAR路由器=前press.Router();
router.post('/后',函数(请求,响应){
的console.log(request.body.name);
response.send('后达成');
});module.exports =路由器;
编辑:
我已经尝试过,并在我的回应添加的内容类型标题。
不过,这是同样的错误。
在同一code,而我用这个方法后正常工作。
$ http.post('/后',{数据:word.name})。成功(功能(响应){
的console.log(成功);
})错误(功能(错误){
的console.log(失败)
});
您必须在服务器上启用CORS。由于端口都是同一服务器上的不同,将像对待一个跨域请求。
I'm trying to post data from angular to express, however, eachtime I make the post request I get this error.
OPTIONS http://localhost/post/ net::ERR_CONNECTION_REFUSED(anonymous function) @ angular.js:11209s @ angular.js:11002g @ angular.js:10712(anonymous function) @ angular.js:15287m.$eval @ angular.js:16554m.$digest @ angular.js:16372m.$apply @ angular.js:16662(anonymous function) @ angular.js:24283m.event.dispatch @ jquery.js:4670r.handle @ jquery.js:4338
controller.js:29
and the errorCallback response object is:
Object {data: null, status: -1, config: Object, statusText: ""}
I did some tweaking looking at other similar questions on SO, like adding header, content-type etc. But no luck there.
What seems to be the problem here.Thanks
Controller.js
word.add = function(){
console.log(word.name );
$http({
method:'POST',
url:'http://localhost/post/',
data :word.name,
headers: {'Content-Type': 'application/json'}
}).then(function successCallback(response){
console.log(response);
console.log("Successful");
},function errorCallback(response){
console.log(response);
console.log("Unsuccessful");
});
};
Relevant code excerpt from app.js
var routes = require('./routes/index');
app.all('/*', function (request, response, next) {
response.header("Access-Control-Allow-Origin", "*");
response.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
response.header("Access-Control-Allow-Headers", "X-Requested-With, Content-Type");
next();
});
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use('/post', routes);
index.js
var express = require('express');
var router = express.Router();
router.post('/post', function(request, response){
console.log(request.body.name);
response.send('Reached post');
});
module.exports = router;
Edit: Hi, I've already tried and added the content-type header in my response.Still,It's the same error.
The same code works fine while I use this method to post.
$http.post('/post',{data: word.name}).success(function(response) {
console.log("success");
}).error(function(err){
console.log("failure")
});
You must enable CORS on your server. Since the port is different on the same server it will treat it like a cross domain request.
