Angularjs中$http以post請求通過消息體傳遞參數的實現方法

本文實例講述了Angularjs中$http以post請求通過消息體傳遞參數的方法。分享給大家供大家參考，具體如下：

Angularjs中，$http以post在消息體中傳遞參數，需要做以下修改，以確保消息體傳遞參數的正確性。

一、在聲明應用的時候進行設置：

var httpPost = function($httpProvider) {
  /*******************************************
  說明：$http的post提交時，糾正消息體
  ********************************************/
  // Use x-www-form-urlencoded Content-Type
  $httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded;charset=utf-8';
  /*
   * The workhorse; converts an object to x-www-form-urlencoded serialization.
   * @param {Object} obj
   * @return {String}
   */
  var param = function(obj) {
    var query = '', name, value, fullSubName, subName, subValue, innerObj, i;
    for (name in obj) {
      value = obj[name];
      if (value instanceof Array) {
        for (i = 0; i < value.length; ++i) {
          subValue = value[i];
          fullSubName = name + '[' + i + ']';
          innerObj = {};
          innerObj[fullSubName] = subValue;
          query += param(innerObj) + '&';
        }
      } else if (value instanceof Object) {
        for (subName in value) {
          subValue = value[subName];
          fullSubName = name + '[' + subName + ']';
          innerObj = {};
          innerObj[fullSubName] = subValue;
          query += param(innerObj) + '&';
        }
      } else if (value !== undefined && value !== null)
        query += encodeURIComponent(name) + '=' + encodeURIComponent(value) + '&';
    }
    return query.length ? query.substr(0, query.length - 1) : query;
  };
  // Override $http service's default transformRequest
  $httpProvider.defaults.transformRequest = [
    function(data) {
      return angular.isObject(data) && String(data) !== '[object File]' ? param(data) : data;
    }
  ];
};
var ngApp = angular.module('wtApp', ['ngCookies'], httpPost);

二、調用$http post

$http({
  method: 'POST',
  url: 'GetData.ashx',
  params: { id: '1002' },//params作為url的參數
  data: { keyName: 'qubernet' }//作為消息體參數
}, function (data) {
});
