问题（angularjs（$ HTTP））

Question

与POST请求的执行问题（angularjs（$ HTTP））

我试图执行一个POST请求，但出现以下错误：

Error: Unexpected request: POST http://192.168.88.54:3000 
No more request expected

at HTMLButtonElement.<anonymous> (file:///Users/vasyasemenov/workspace/tamua/ogogo-frontend/build/vendor/angular/angular.js:17690:21) 

我执行POST请求：

angular.module('App') 
.config(['$httpProvider', 
    function($httpProvider) { 
     $httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded'; 
    } 
]) 
.service('API', function API($http, $q, PROD, PROD_HOST, DEV_HOST, API_TOKEN) { 
    var self = this; 

    self.host = (PROD ? PROD_HOST : DEV_HOST); 

    self.performRpcCall = { 
     post: function(url, params) { 
      var deferred = $q.defer(); 
      var data = { 
       jsonrpc: '2.0', 
       params: params, 
       method: url 
      }; 
      $http.post(self.host, data).success(function(data) { 
       if(data.result) { 
        deferred.resolve(data.result); 
       }else{ 
        deferred.reject(data.error); 
       } 
      }).error(function(data, status, headers, config) { 
       deferred.reject(data); 
      }); 
      return deferred.promise; 
     } 
    }; 

    self.registerUser = function(params) { 
     params.token = API_TOKEN; 
     return self.performRpcCall.post('/api/users', params); 
    }; 
}); 

哪里错误？谢谢

不知道这是不是问题，但之前将对象作为数据参数传递给$http.post之前遇到了麻烦。

要更正我用jQuery的$.params(data)在过去或...

data = { 
    someVar : someVal, 
    anotherVar : anotherVal 
}; 
return $http({ 
     method : 'POST', 
     url : 'someURL/path/to/api/script', 
     params : data, 
     headers : {'Content-Type' : 'application/x-www-form-urlencoded'} 
    }).success(function(response){ 
     return (angular.isDefined(response.data.result)) ? response.data.result : response.data.error; 
    }).error(function(response){ 
     return { data : response.data, status : response.status }; 
    }); 

数据传递$http配置对象时得到JSONified为params变种。当然，您已经与供应商一起设置了标头。还有一个数据配置属性，我没有使用过，但我认为它也是一样的，但不是将数据JSON化成字符串，而是将它作为消息数据合并到头中。
