在Azure Web App中的nuget更新之后，Web API返回HttpResponseMessage对象 [英] Web API returning HttpResponseMessage object after nuget updates in Azure Web App

问题描述

我使用的是Web API 5，它运行良好，我返回了一个Content = new StringContent("content here")的HttpResponseMessage对象，并在调用该API时获得了预期的内容.

I'm using Web API 5, it's has been working fine, I return a HttpResponseMessage object with Content = new StringContent("content here") and get the expected content when calling the API.

[HttpPost]
    public async Task<HttpResponseMessage> GetData([FromBody]DataObject input)
    {
      .....
      return new HttpResponseMessage(HttpStatusCode.OK)
            {
                Content = new StringContent(JsonConvert.SerializeObject(returnModel))
            };
    }

但是，我最近更新了许多MVC和.NET NuGet程序包，现在，尽管项目在本地编译并可以正常运行，但是当我部署到Azure Web App时，调用API会返回不包含任何内容的实际HttpResponseMessage对象，而不是内容:

However, I recently updated a number of MVC and .NET NuGet packages, and now, while the project compiles and runs fine locally, when I deploy to an Azure Web App, calling the API returns the actual HttpResponseMessage object with no content, rather than the content:

{
"Version": {
    "_Major": 1,
    "_Minor": 1,
    "_Build": -1,
    "_Revision": -1
},
"Content": {
    "Headers": [
        {
            "Key": "Content-Type",
            "Value": [
                "text/plain; charset=utf-8"
            ]
        }
    ]
},
"StatusCode": 200,
"ReasonPhrase": "OK",
"Headers": [],
"RequestMessage": null,
    "IsSuccessStatusCode": true
}

通常，同一调用将返回Content对象的JSON字符串.是否有一些奇怪的依赖问题发生，关于如何在不回滚所有nuget更新的情况下进行修复的任何想法?还是我需要更新Azure Web App上的设置(已经设置了.NET 4.7).

Normally this same call would return a JSON string of the Content object. Is there some odd dependency issue happening, any ideas on how to fix without rolling back all of the nuget updates? Or do I need to update a setting on the Azure Web App (already have .NET 4.7 set).

推荐答案

假设ApiController，可以将操作重构为使用最新建议的语法.

Well assuming an ApiController, the action can be refactored to use the more recent advised syntax.

[HttpPost]
public async Task<IHttpActionResult> GetData([FromBody]DataObject input) {

    //.....code awaited here and gets 'returnModel'

    return Ok(returnModel);
}
