Question

当我从http://localhost:5086/发出GET请求时效果很好，发送到 api / FileBrowser ，但当我尝试从http://localhost:5086/Home/Index向api发出请求时，添加到网址controller主页和请求发送到 / Home / api / FileBrowser

请帮助我做错了什么？

带有2种方法的ApiController

public FileBrowserModel Get()
    {
        var result = new FileBrowserModel();
        List<string> drives = new List<string>();
        foreach (var drive in DriveInfo.GetDrives())
        {
            var path = drive.Name;
            FileManagerCounter fmCounter = new FileManagerCounter(path);
            result.CountTo10Mb += fmCounter.CountTo10Mb;
            result.Countfrom10To50Mb += fmCounter.Countfrom10To50Mb;
            result.CountFrom100Mb += fmCounter.CountFrom100Mb;
            drives.Add(path);
        }
        result.SubDirectories = new List<string>(drives);
        return result;
    }
    [CacheOutput(ServerTimeSpan = 150)]
    [System.Web.Http.HttpGet]
    public FileBrowserModel Get(string path)
    {
        var result = new FileBrowserModel();

        try
        {
            try
            {
                result.ParentPath  = Directory.GetParent(path).FullName;
            }
            catch (Exception)
            {

            }

            var files = Directory.GetFiles(path).ToList();
            result.Files = new List<string>(files);
            result.CurrentPath = path;
            FileManagerCounter fmCounter = new FileManagerCounter(path);
            result.CountTo10Mb = fmCounter.CountTo10Mb;
            result.Countfrom10To50Mb = fmCounter.Countfrom10To50Mb;
            result.CountFrom100Mb = fmCounter.CountFrom100Mb;

            var subDirectories = Directory.GetDirectories(path).ToList();
            result.SubDirectories = new List<string>(subDirectories);
        }
        catch (Exception ex)
        {
            throw new HttpResponseException(HttpStatusCode.InternalServerError);
        }

        return result;
    }

    $scope.getFileBrowsing = function (path) {
        $scope.isLoading = true;

Answer 1

编辑：War10ck的答案是简单的解决方案。

以下是正确构建相对网址的替代解决方案

问题是，您将url值硬编码为“api / FileBrowser”。因此，基于当前页面，此值将会更改。如果您在主页上，它将是Home/api/FileBrowser。

你应该做的是建立正确的相对网址。由于您使用的是asp.net mvc页面，因此您可以使用Url.Action帮助程序方法来构建正确的相对URL。您可以在剃刀视图中生成应用程序路径的值，并将其传递给角度控制器/数据服务并使用它。

所以在你的剃刀视图中，

<script>
    var myApp = myApp || {};
    myApp.Urls = myApp.Urls || {};
    myApp.Urls.baseUrl = '@Url.Content("~")';       
</script>
<script src="~/Scripts/AngularControllerForPage.js"></script>
<script>
    var a = angular.module("FileBrowserApp").value("appSettings", myApp);
</script>

在角度控制器中，您可以访问此appSettings。

var app = angular.module("FileBrowserApp", []);
var ctrl = function (appSettings) {

    var vm = this;

    vm.baseUrl = appSettings.Urls.baseUrl;
    //build other urls using the base url now
    var fileBrowserUrl= vm.baseUrl + "api/FileBrowser";
    alert(fileBrowserUrl);
    //You can use this variable value for your http call now
    $http({
            url: fileBrowserUrl+ "?path=" + encodeURIComponent(path),
            method: "GET"
        }).success(function (data) {
            $scope.fileBrowserModel = data;
            $scope.isLoading = false;
        });

};
app.controller("fileBrowserController", ctrl)

您可以在您的数据服务和指令等中访问它，并使用它来构建正确的网址。

您也可以考虑将您的http调用从角度控制器移动到数据服务。

Answer 2

如果您完全确定您的Web API图层将始终存在于根域之上的一层，那么您可以将ajax调用中的网址更改为：

url: "/api/..."

无论网站的结构如何，都会相对于根域调用api。
