Question

我正在通过带有HttpClient的mvc控制器来使用外部web api。我的web api确实返回了json格式的内容。

如何在使用web api时在我的mvc控制器中返回相同的json格式的web api响应内容？我期待这样的事情。

public async JsonResult GetUserMenu()
{
    using (HttpClient client = new HttpClient())
    {
        client.BaseAddress = new Uri(url);
        HttpResponseMessage response = await client.GetAsync(url);

        if (response.IsSuccessStatusCode)
        {
             return await response.Content.ReadAsJsonAsync();
        }
    }
}

Answer 1

使用Json.Net你可以这样做：

public async Task<JsonResult> GetUserMenu()
{
    string result = string.Empty;

    using (HttpClient client = new HttpClient())
    {
        client.BaseAddress = new Uri(url);
        HttpResponseMessage response = await client.GetAsync(url);

        if (response.IsSuccessStatusCode)
        {
            result = await response.Content.ReadAsStringAsync();
        }
    }

    return Json(Newtonsoft.Json.JsonConvert.DeserializeObject<dynamic>(result));
}

下面是为操作插入日志的示例。

    [HttpPost]
    public async System.Threading.Tasks.Task<ActionResult> ChangePassword(ChangePasswordInfo model)
    {
        var omodelPwd = loginContext.UsersChangePasswordRequest(objAuthModel.oUsers.iID);

        TempData[LKTransferDashboardCommon.Notification] = JsonConvert.SerializeObject(new Response { Success = false, ResponseString = "Invalid Old Password!" });
        var auditLog = LKTransferDashboardCommon.PrepareAuditLogData(
                                           "ChangePassword-Fail",
                                           objAuthModel.oUsers.iID,
                                           nameof(ChangePassword),
                                           Request.ServerVariables["REMOTE_ADDR"],
                                           "AdministrationController",
                                           objAuthModel.oUsers.Name
                                       );
         await AuditLogHelper.ExecuteAsync(auditLog, null, null, null, null, null).ConfigureAwait(false);

         return View(model);
     }

从mvc控制器消耗web api时返回json结果
