无法在 Angular 1 应用程序中设置对变量的 api 调用结果

我正在尝试调用 api，并将结果设置为变量。当我将其记录在控制台中时，我能够成功进行调用并查看数据，但后来当我尝试使用该变量时，它是未定义的。

这是相关代码：

        var postParams = {
            "code": input.Code,
            "number": input.Number
        }

        var result;

        try {
            $http.post("/api/DetailAPI/GetDetails?code=" + input.Code + "&number=" + input.Number, postParams).success(function (details) {
                console.log(details);
                result = JSON.parse(details);
            });
        }
        catch (error) {
            console.log(error);
        }

        console.log(result);

第一个 console.log(details) 显示我期望列为“对象”的数据。当调用 console.log(result) 时，结果是未定义的。

我尝试过使用和不使用 JSON.parse() 并得到相同的结果。

我知道 api 调用正在工作，因为我可以在控制台中看到数据。问题是我无法将此数据存储在结果变量中。

如何让 Angular 真正将从 api 调用获得的数据放入变量中？

I am trying to call an api, and set the results to a variable. I am able to successfully make the call and see the data when I log it in the console, but later when I try to use the variable it is undefined.

Here is the relevant code:

        var postParams = {
            "code": input.Code,
            "number": input.Number
        }

        var result;

        try {
            $http.post("/api/DetailAPI/GetDetails?code=" + input.Code + "&number=" + input.Number, postParams).success(function (details) {
                console.log(details);
                result = JSON.parse(details);
            });
        }
        catch (error) {
            console.log(error);
        }

        console.log(result);

The first console.log(details) shows the data I am expecting listed as "Object". When console.log(result) is called result is undefined.

I have tried with and without JSON.parse() and get the same result either way.

I know the api call is working, since I can see the data in the console. The issue is that I cannot store this data in my result variable.

How do I get Angular to actually put the data I get from the api call into a variable?
