使用 $http POST Content-Type application/x-www-form-urlencoded 访问 API [英] Accessing API with $http POST Content-Type application/x-www-form-urlencoded
问题描述
我正在尝试访问这个 REST API，它接受三个参数:stationId、crusherId、monthYear我在 AngularJS 中这样做:
I am trying to access this REST API, which accepts three parameters:
stationId, crusherId, monthYear
I am doing it like this in AngularJS as:
$http({
//headers: {'Content-Type':'application/x-www-form-urlencoded; charset=UTF-8'},
//headers: {'Content-Type': 'application/json; charset=UTF-8'},
headers: {
'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8',
'Accept': 'application/json'
},
url: 'https://myurl../api/getHPData',
method: 'POST',
data: {
stationId: 263,
crusherId: 27,
monthYear: '2016-4'
}
})
.then(function(data, status, headers, config) {
//console.log(JSON.stringify(response));
console.log(data);
})
.catch(function(error){
//console.log("Error: " + JSON.stringify(error));
console.log(error);
})
但我总是得到这个:
Object {data: "{"result":"false"}", status: 200, config: Object, statusText: "OK", headers: function}
Object {data: "{"result":"false"}", status: 200, config: Object, statusText: "OK", headers: function}
或
{"data":"{\"result\":\"false\"}","status":200,"config":{"method":"POST","transformRequest":[null],"transformResponse":[null],"headers":{"Content-Type":"application/x-www-form-urlencoded;charset=UTF-8","Accept":"application/json"},"url":"https://myurl../api/getHPData","data":{"stationId":263,"crusherId":27,"monthYear":"2016-4"}},"statusText":"OK"}
{"data":"{\"result\":\"false\"}","status":200,"config":{"method":"POST","transformRequest":[null],"transformResponse":[null],"headers":{"Content-Type":"application/x-www-form-urlencoded; charset=UTF-8","Accept":"application/json"},"url":"https://myurl../api/getHPData","data":{"stationId":263,"crusherId":27,"monthYear":"2016-4"}},"statusText":"OK"}
如果我将 header Content-Type 更改为:
If I change header Content-Type to:
headers: {'Content-Type': 'application/json; charset=UTF-8'},
它给出:
Object {data: null, status: -1, config: Object, statusText: "",headers: function}
Object {data: null, status: -1, config: Object, statusText: "",headers: function}
或
{"data":null,"status":-1,"config":{"method":"POST","transformRequest":[null],"transformResponse":[null],"headers":{内容类型":应用程序/json；charset=UTF-8","Accept":"application/json, text/plain,/"},"url":"https://myurl../api/getHPData","data":{"stationId":263,"crusherId":27,"monthYear":"2016-4"}},"statusText":""}
{"data":null,"status":-1,"config":{"method":"POST","transformRequest":[null],"transformResponse":[null],"headers":{"Content-Type":"application/json; charset=UTF-8","Accept":"application/json, text/plain, /"},"url":"https://myurl../api/getHPData","data":{"stationId":263,"crusherId":27,"monthYear":"2016-4"}},"statusText":""}
我做错了什么，请帮助我.

注意:我可以在 jQuery 中做到这一点:
Note:
I can do it in jQuery as:
<script>
$(document).ready(function() {
get_homepage_data(263, 27, '2016-04');
function get_homepage_data(stationIds, crusherIds, date) {
var url = "https://myurl../api/getHPData";
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) {
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 script 是:
Output of above script is script is:
- 值为:{"stationId":263,"crusherId":27,"monthYear":"2016-04"}
- XHR 完成加载:POST"https://myurl../api/getHPData.
- foo 的日志是:26862094
- 26862094"百万为:2686.2094万
这是完美的.:)
推荐答案
发布 URL 编码的表单数据时，使用 $httpParamSerializer 服务:
When posting form data that is URL encoded, transform the request with the $httpParamSerializer service:
$http({
headers: {'Content-Type':'application/x-www-form-urlencoded; charset=UTF-8'},
url: 'https://fnrc.gov.ae/roayaservices/api/getHPData',
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 服务会自动解析来自 JSON 编码对象的结果，但此 API 返回的是从对象中双重序列化的字符串.transformResponse 函数解决了这个问题.
Normally the $http service automatically parses the results from a JSON encoded object but this API is returning a string that has been doubly serialized from an object. The transformResponse function fixes that problem.
