从 http 内部函数返回数据 [英] Return data from http inside function
问题描述
我正在使用 this 和 this 参考,从 http 请求返回数据在函数内部:
I'm using this and this reference, to return data from an http-request inside a function:
function getdetails(id) {
var datafordetails = {
data1: {
item1: "",
item2: ""
},
data2: {
item3: "",
ID: id
}
};
var jsonDataDetails = JSON.stringify(datafordetails);
return $http({
url: "http://...",
method: "POST",
data: jsonDataDetails,
dataType: "json",
timeout: 5000,
contentType: 'application/json; charset=utf-8'
})
.then(function (res) {
var data = res.data;
responsedata=data.d;
return responsedata;
},function (error) {
$scope.status = status;
console.log("Unable to update. No internet?");
})
}
我的目标是 var testing = getdetails('12345');
为我提供该 ID 的响应数据,但我正在返回 Promise {$$state: Object...
My goal is that var testing = getdetails('12345');
gives me the responsedata for that ID, but I'm getting back Promise {$$state: Object...
我做错了什么?非常感谢!
What am I doing wrong? Thanks a lot!
推荐答案
你得到的输出只不过是一个由 $http.get
方法返回的 promise 对象.基本上,您需要将 .then
函数放在 getdetails2
函数上,以便在 resolve
/reject
时从承诺对象中获取数据>.
The output you are getting is nothing but a promise object which has been returned by the $http.get
method. Basically you need to put .then
function over getdetails2
function for getting data from the promise object when it resolve
/reject
.
代码
getdetails2('12345').then(function(data){ //success callback
//you will get data here in data parameter of function,
var testing = data;
}, function(error){ //error callback
console.log(error)
})
