我有以下REST
服务,我必须访问POST
方法,
我可以通过jQuery
访问它,但我不知道如何使用AngularJS
(v1)
<string xmlns = "http://schemas.microsoft.com/2003/10/Serialization/">
<script id = "tinyhippos-injected" />
{
"volumeResult": {
"gyydt": "9771241.17704773",
"gytotal": "29864436.1770477",
"gybudgeted": "29864436.1770477",
"lyydt": "10197350",
"lytotal": "27859381",
"lybudgeted": "10197350",
"cyytd": "6992208",
"lastUpdate": "March-2017"
},
"valueResult": {
"gyydt": "26862094",
"gytotal": "68217952",
"gybudgeted": "68232952",
"lyydt": "0",
"lytotal": "0",
"lybudgeted": "0",
"cyytd": "68217952",
"lastUpdate": "March-2017"
},
"trucksResult": {
"gyydt": "165951",
"gytotal": "497879",
"gybudgeted": "497879",
"lyydt": "168822",
"lytotal": "468814",
"lybudgeted": "168822",
"cyytd": "119442",
"lastUpdate": "March-2017"
}
}
</string>
这是我的 controller.js :
angular.module('starter.controllers', [])
.controller('DashCtrl', ['$scope', '$http', function ($scope, $http) {
$http({
//headers: {'Content-Type':'application/x-www-form-urlencoded; charset=UTF-8'},
headers: {'Content-Type' : 'application/json'},
url: 'https://myurl../api/getHPData',
method: 'POST',
// data: data,
params: {
"stationId": 263,
"crusherId": 27,
"monthYear": '2016-04'
}
})
.then(function (response) {
console.log(response);
})
// I don't have to use .success and .error function as they are [depricated][2]
//.success(function (data, status, headers, config) {
// $scope.greeting = data;
// var Result = JSON.stringify(data);
// var Result = JSON.parse(data);
//})
//.error(function (error, status, headers, config) {
// console.log("====================== Error Status is: " + error);
// console.log("====================== Status is: " + status);
// console.log("====================== Error occured");
//})
}]) // eof controller DashCtrl
.controller('MapsCtrl', function($scope) {})
.controller('AccountCtrl', function($scope) {
$scope.settings = {
enableFriends: true
};
});
我想要的是: 的&#34; volumeResult&#34; &GT; &#34; gytotal&#34;
问题:
对象{数据:&#34; {&#34;结果&#34;:&#34; false&#34;}&#34;,状态:200,配置:对象,statusText:&#34;确定& #34;,header:function}
和
当我在没有引号的情况下传递monthYear
时,它将(算术)处理为(2016-04 = 2012)
由于服务是POST
,但当我在Chrome Developers Tool
中进行分析时,我得到:(查询字符串,这不是故意POST)
ionic.bundle.js:25005 XHR完成加载:POST &#34; https://myurl../api/getHPData?crusherId=27&monthYear=2016-4&stationId=263&#34;
可能的解决方案: 要么我使用错误的标题:
headers: {
'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8',
'Accept': 'application/json'
},
或标题可能是,
headers: {
'Content-Type': 'application/json',
'Accept': 'application/json'
},
或者根据我的朋友说:
当我更改您的代码以使用上面的代码时,我收到此错误:
"{"Message":"The requested resource does not support http method 'OPTIONS'."}"
这意味着存在CORS (Cross-origin Resource Sharing)问题。 Chrome正试图进行预检&#34;要求允许 CORS,但服务器不知道如何处理它。
但我不认为这是因为我正在收到:
对象{数据:&#34; {&#34;结果&#34;:&#34; false&#34;}&#34;,状态:200,配置:对象, statusText:&#34; OK&#34;,headers:function}
来自服务器。注意:{"result":"false"}
是服务器在找不到数据或传递错误的参数时显示的消息。另外,jQuery代码证明我可以访问服务器。 :)
修改
jQuery Snippet:
<script>
$(document).ready(function() {
get_homepage_data(263, 27, '2016-04');
function get_homepage_data(stationIds, crusherIds, date) {
var url = "https://myurl..";
var data_to_send = {
'stationId': stationIds,
'crusherId': crusherIds,
'monthYear': date
};
console.log("Value is: " + JSON.stringify(data_to_send));
//change sender name with account holder name
// console.log(data_to_send)
$.ajax({
url: url,
method: 'post',
dataType: 'json',
//contentType: 'application/json',
data: data_to_send,
processData: true,
// crossDomain: true,
beforeSend: function () {
}
, complete: function () {}
, success: function (result1) {
// I know I can do it in one line but lazy enough to edit it here :p
var Result = JSON.parse(result1);
var value_data = Result["valueResult"];
var foo = value_data["gyydt"];
console.log("Log of foo is: " + foo);
var foo2 = 0;
// 10 lac is one million.
foo2 = foo / 1000000 + ' million';
console.log(JSON.stringify(value_data["gyydt"]) + " in million is: " + foo2);
}
, error: function (request, error) {
return false;
}
});
}
}); // eof Document. Ready
</script>
以上脚本的输出是脚本:
价值是:{&#34; stationId&#34;:263,&#34; crusherId&#34;:27,&#34; monthYear&#34;:&#34; 2016-04&#34;} XHR完成加载:POST&#34; https://myurl../api/getHPData&#34;。 foo的日志是:26862094 &#34; 26862094&#34;百万是:26.862094万 这确实很完美。 :)

尝试以这种方式使用$ http ..
$http.post("https://myurl../..",JSON.stringify({
stationId: 263,
crusherId: 27,
monthYear:'2016-04'
})).then(function(res){
console.log(res);
}).catch(function(errors){
console.log(errors);
})

我得到了答案。 Whao。
谢谢你georgeawg的回答:
他说:
发布经过网址编码的表单数据时,请使用$httpParamSerializer service转换请求:
$http({
headers: {'Content-Type':'application/x-www-form-urlencoded; charset=UTF-8'},
url: 'https://myurl..',
method: 'POST',
transformRequest: $httpParamSerializer,
transformResponse: function (x) {
return angular.fromJson(angular.fromJson(x));
},
data: {
"stationId": 263,
"crusherId": 27,
"monthYear": '2016-04'
}
})
.then(function(response) {
console.log(response);
$scope.res = response.data;
console.log($scope.res);
});
通常$http
服务会自动解析JSON编码对象的结果,但此API返回一个已从对象进行双重序列化的字符串。 transformRespons
e函数修复了这个问题。
现在我可以将gytotal
的值设为:
var myData = parseFloat(response.data.valueResult.gytotal);
console.log(myData);
