.NET MVC 4 WebAPI POST不起作用 [英] .NET MVC 4 WebAPI POST not working

问题描述

核心问题:GET有效，POST不起作用.我是WebAPI的新手，所以我可能在做一些愚蠢的事情，但是我在网上搜寻了很多，试图弄清为什么它不起作用.

Core problem: GET works, POST doesn't. I'm new to WebAPI so I'm probably doing something stupid, but I've poked around quite a bit on the 'net trying to figure out why this isn't working.

相当简单的WebAPI C#应用程序.我试图将其归结为非常简单的路线:

Fairly simple WebAPI C# app. I've tried to get this down to very simple routes:

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );

        // Add a route where action is supplied, i.e. api/csv/LoadToSQL
        config.Routes.MapHttpRoute(
            name: "ActionApi",
            routeTemplate: "api/{controller}/{action}"
        );

控制器类:

public class CsvController : ApiController
{
    // GET api/csv
    public IEnumerable<string> Get()
    {
        return new string[] { "value1", "value2" };
    }

    // GET api/csv/name
    public string Get(string csvName)
    {
        return "value";
    }

    // POST - api/csv/LoadToSQL
    // Load a CSV to SQL
    [HttpPost]
    [ActionName("LoadToSQL")]
    public HttpResponseMessage LoadToSQL(
        string storageAccount,
        string accessKey,
        string containerName,
        string csvFileName,
        string connectionString,
        string targetDatabaseName,
        string targetTableName)
    {
        try
        {
            // Retrieve storage account from connection string.
            CloudStorageAccount blobStorage = CloudStorageAccount.Parse(storageAccount);

在本地启动并连接Fiddler.尝试GET;作品:

Start it up locally and connect Fiddler. Try a GET; works:

尝试POST-失败:

我最初的实现只有

    // POST - api/csv
    // Load a CSV to SQL
    public HttpResponseMessage Post(

但是没有用，所以我开始尝试添加特定的路线和动词修饰.

but that didn't work so I started trying to add specific routes and verb decorations.

无论我做什么，似乎都没有看到针对此控制器的POST动作.

It just doesn't seem to see the POST action against this controller no matter what I do.

有什么想法吗?

更新-以下每个答案的正确答案是:

UPDATE - per answer below, the correct route to make this work is:

        // Add a route where action is supplied, i.e. api/csv/LoadToSQL
        config.Routes.MapHttpRoute(
            name: "ActionApi",
            routeTemplate: "api/{controller}/{action}/{storageAccount}/{accessKey}/{containerName}/{csvFileName}/{connectionString}/{targetDatabaseName}/{targetTableName}"
        );

这显示了POST请求的所有参数.

This shows all the parameters to the POST request.

推荐答案

如果愿意，您可以替换您的方法以使其更清晰，更干净

You can replace your method to be more clear and clean if you like so

1-使用您的选项声明一个类

1- declare a class with your options

public class LoadToSqlData
{
   public string storageAccount {get; set;}
   public string accessKey {get; set;}
   public string containerName {get; set;}
   public string csvFileName {get; set;}
   public string connectionString {get; set;}
   public string targetDatabaseName {get; set;}
   public string targetTableName {get; set;}
}

2-声明您的方法是:

2- Declare your method to be :

[HttpPost]
[ActionName("ActionApi")]
[Route("api/Csv/LoadToSQL")]
public HttpResponseMessage LoadToSQL([FromBody]LoadToSqlData data)

注意[Route],[ActionName]和[FromBody]属性的用法.
