$httpProvider.defaults.transformRequest

将形如 中的数据转换为form数据提交

$http.post("/url", {
      id: 1,
      name: "greengerong"
    }
});

效果等同

$http.post("/url", {
      id: 1,
      name: "greengerong"
    }, {
      transformRequest: function(request) {
        return $.param(request);
    }
});

跨域的话,如下

    $httpProvider.defaults.useXDomain = true;  
       delete $httpProvider.defaults.headers.common['X-Requested-With'];  
    // Use x-www-form-urlencoded Content-Type  
     $httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';  
     $httpProvider.defaults.headers.put['Content-Type'] = 'application/x-www-form-urlencoded';
