角度$资源删除不会将body发送到express.js服务器 [英] angular $resource delete won't send body to express.js server

问题描述

hye，

我正在服务器端使用angular.js和node.js（Express.js）构建一个应用程序。

由于某些原因，我在处理删除请求时遇到问题。没有身体正在服务器端。

这是我的angular.js资源代码：

  $ scope.deleteProject = function（projectName）{
 var postData = {username：'name'，projectName：projectName}; 
 Project.deleteProject.delete（{}，postData，
 function（res）{
 alert（'Project Deleted'）; 
}，
函数（err） {
 alert（err.data）; 
}）; 
} 
  

在服务器端我有这个：

  var deleteProject = function（req，res）{
 console.log（req.body）; 
 console.log（req.params）; 
 if（req.body.projectName）{
 // do something 
 return res.send（200）; 
} 
 else 
 return res.send（400，'没有指定项目名称'）; 
} 
  

现在由于某种原因，没有任何身体！它是空的
i将路由定义为app.delete。如果我将node.js中的路由更改为post，并在angular.js中保存，则该路由可以正常运行。

我在这里错过了什么（撞上我的头）。

谢谢。

解决方案

根据这个堆栈溢出问题和 $ http 服务源代码，一个 DELETE 请求使用 $ http 不允许在请求正文中发送数据。 DELETE请求的规范对于是否有一个应该允许请求机构，但Angular不支持它。

允许请求机构的唯一方法是 POST ， PUT 和 PATCH 。所以这个问题并不在您的代码中，而是在Angular的 $ http 服务中。

我的建议是使用通用的 $ http（...）函数并传递正确的方法$ {

$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ '，
data：{...}，
标题：{'Content-Type'：'application / json; charset = utf-8'}
}）

hye,

i am building an app with angular.js and node.js (Express.js) on the server side.

for some reason i am having a problem handling a delete request. no body is getting to the server side.

this is my angular.js resource code:

$scope.deleteProject = function(projectName){
    var postData = {username: 'name', projectName: projectName};
    Project.deleteProject.delete({}, postData,
        function(res){
            alert('Project Deleted');
        },
        function(err){
            alert(err.data);
    });
}

on the server side i have this:

var deleteProject = function(req, res){
    console.log(req.body);
    console.log(req.params);
    if (req.body.projectName){
        //do something
        return res.send(200);
    }
    else
        return res.send(400, 'no project name was specified');
}

now for some reason there is no body at all!! it is empty. i have defined the route as app.delete.

if i change the route in node.js to post and in angular.js to save it works fine.

what am i missing here (banging my head).

thanks.

解决方案

As per this stack overflow question and the $http service source code, a DELETE request using $http does not allow for data to be sent in the body of the request. The spec for a DELETE request is somewhat vague on whether or not a request body should be allowed, but Angular does not support it.

The only methods that allow for request bodies are POST, PUT, and PATCH. So the problem is not anywhere in your code, its in Angular's $http service.

My suggestion would be to use the generic $http(...) function and pass in the proper method:

$http({
    method: 'DELETE',
    url: '/some/url',
    data: {...},
    headers: {'Content-Type': 'application/json;charset=utf-8'}
})
