我也遇到过类似的问题，我想知道这个是否也有用:https://stackoverflow.com/a/11443066

var xsrf = $.param({fkey: "key"});
$http({
    method: 'POST',
    url: url,
    data: xsrf,
    headers: {'Content-Type': 'application/x-www-form-urlencoded'}
})

问候,

It's not angular's fault. Angular is designed to work in JSON world. So when $http service send AJAX request, it send all your data as a payload, not as form-data so that your backend application can handle it. But jQuery does some things internally. You instruct jQuery's $ajax module to bind form-data as JSON but before sending AJAX request, it serialized JSON and add application/x-www-form-urlencoded header. This way your backend application able to received form-data in form of post parameters and not JSON.

但是你可以修改angular $http服务的默认行为

添加标题 序列化json

$httpParamSerializerJQLike是angular的内置服务，它以同样的方式序列化json。jQuery的参数。

$http({
    method: 'POST',
    url: 'request-url',
    data: $httpParamSerializerJQLike(json-form-data),
    headers: {
      'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8;'
    }
});

如果你需要一个插件先将表单数据序列化成JSON，可以使用这个插件https://github.com/marioizquierdo/jquery.serializeJSON

问候,

在我的例子中，我是这样解决问题的:

var deferred = $q.defer();

$http({
    method: 'POST',
    url: 'myUri', 
    data: $.param({ param1: 'blablabla', param2: JSON.stringify(objJSON) }),
    headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
}).then(
    function(res) {
        console.log('succes !', res.data);
        deferred.resolve(res.data);
    },
    function(err) {
        console.log('error...', err);
        deferred.resolve(err);
    }
);
return deferred.promise;

您需要使用JSON。为每个包含JSON对象的参数进行stringify，然后使用"$. stringify "构建数据对象。param”:-)

注意:我的“objJSON”是一个JSON对象，包含数组，整数，字符串和html内容。他的总大小是>3500个字符。

我喜欢使用函数将对象转换为post参数。

myobject = {'one':'1','two':'2','three':'3'}

Object.toparams = function ObjecttoParams(obj) {
    var p = [];
    for (var key in obj) {
        p.push(key + '=' + encodeURIComponent(obj[key]));
    }
    return p.join('&');
};

$http({
    method: 'POST',
    url: url,
    data: Object.toparams(myobject),
    headers: {'Content-Type': 'application/x-www-form-urlencoded'}
})

这段代码为我解决了这个问题。它是一个应用级解决方案:

moduleName.config(['$httpProvider',
  function($httpProvider) {
    $httpProvider.defaults.transformRequest.push(function(data) {
        var requestStr;
        if (data) {
            data = JSON.parse(data);
            for (var key in data) {
                if (requestStr) {
                    requestStr += "&" + key + "=" + data[key];
                } else {
                    requestStr = key + "=" + data[key];
                }
            }
        }
        return requestStr;
    });
    $httpProvider.defaults.headers.post["Content-Type"] = "application/x-www-form-urlencoded";
  }
]);
