angular post带参数后台取不到值

解决方法1：配置$httpProvider；

var myApp = angular.module('app',[]);  
 myApp.config(function($httpProvider){  

   $httpProvider.defaults.transformRequest = function(obj){  
     var str = [];  
     for(var p in obj){  
       str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));  
     }  
     return str.join("&");  
   }  

   $httpProvider.defaults.headers.post = {  
        'Content-Type': 'application/x-www-form-urlencoded'  
   }  

});  

解决方法2：在post中配置；

$http({  
   method:'post',  
   url:'post.php',  
   data:{name:"aaa",id:1,age:20},  
   headers:{'Content-Type': 'application/x-www-form-urlencoded'},  
   transformRequest: function(obj) {  
     var str = [];  
     for(var p in obj){  
       str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));  
     }  
     return str.join("&");  
   }  
}).success(function(req){  
       console.log(req);  
})  

或者3：写在服务中

wmApp.factory('httpConf',function(){
    var httpConf={};
    httpConf.post={
        headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
        transformRequest: function (data) {
            return $.param(data);
        }}
    return httpConf;
});
