使用角度http.post方法发布 - xmlhttprquest无法加载服务

Angular $http.post method is not posting JSON to service (RESTFul service, node service). Showing the following error :

Angular $ http.post方法未将JSON发布到服务（RESTFul服务，节点服务）。显示以下错误：

XMLHttpRequest cannot load /some/service. Invalid HTTP status code 404

XMLHttpRequest无法加载/ some / service。无效的HTTP状态代码404

Here is the posted code

这是发布的代码

$http({method:'POST', url:'/some/service/',data:{"key1":"val1","key2":"val2"}}).success(function(result){
  alert(result);
});

The same code is working with the old version of my chrome i.e, v29...* . I updated my chrome to V30...* . Now, it is not working. Not working in the Firefox as well. Is there any problem with chrome and Firefox?

相同的代码正在使用旧版本的chrome，即v29 ... *。我将我的chrome更新为V30 ...... *。现在，它没有用。也不在Firefox中工作。 Chrome和Firefox有什么问题吗？

Can anybody help?

有人可以帮忙吗？

I came across a similar issue after updating Chrome to version 30.0.1599.101 and it turned out to be a server problem.

在将Chrome更新到版本30.0.1599.101后，我遇到了类似的问题，结果证明是服务器问题。

My server is implemented using Express (http://expressjs.com/) and the code below allowing CORS (How to allow CORS?) works well:

我的服务器使用Express（http://expressjs.com/）实现，下面的代码允许CORS（如何允许CORS？）运行良好：

var express = require("express");
var server = express();

var allowCrossDomain = function(req, res, next) {
    res.header('Access-Control-Allow-Origin', req.headers.origin || "*");
    res.header('Access-Control-Allow-Methods', 'GET,POST,PUT,HEAD,DELETE,OPTIONS');
    res.header('Access-Control-Allow-Headers', 'content-Type,x-requested-with');
    next();
}
server.configure(function () {
    server.use(allowCrossDomain);
});

server.options('/*', function(req, res){
    res.header('Access-Control-Allow-Origin', req.headers.origin || "*");
    res.header('Access-Control-Allow-Methods', 'GET,POST,PUT,HEAD,DELETE,OPTIONS');
    res.header('Access-Control-Allow-Headers', 'content-Type,x-requested-with');
    res.send(200);
});

server.post('/some_service', function (req, res) {
  res.header('Access-Control-Allow-Origin', req.headers.origin);

  // stuff here

  //example of a json response
  res.contentType('json');
  res.send(JSON.stringify({OK: true}));
});

The HTTP request looks like:

HTTP请求如下所示：

$http({
    method: 'POST',
    url: 'http://localhost/some_service',
    data: JSON.stringify({
        key1: "val1",
        key2: "val2"
    }),
    headers: {
        'Content-Type': 'application/json; charset=utf-8'
    }
}).success(
    function (data, status, headers, config) {
        //do something
    }
).error(
    function (data, status, headers, config) {
        //do something
    }
);

As pointed out in here (https://*.com/a/8572637/772020), the idea is to ensure that your server handles properly the OPTIONS request in order to enable CORS.

正如这里所指出的那样（https://*.com/a/8572637/772020），我们的想法是确保您的服务器正确处理OPTIONS请求以启用CORS。

Well, a new chrome update was released a couple of days ago. Check the patch notes from that release if they changed anything security related. My extension stopped working both in FF and Chrome a couple of days ago.

好吧，几天前发布了一个新的Chrome更新。如果他们更改了与安全性相关的任何内容，请检查该发行版中几天前，我的扩展程序停止了在FF和Chrome中的工作。
