错误“405方法不允许”使用body参数在Postman中调用Put方法时 [英] Error "405 Method Not Allow" When Calling Put method in Postman with body parameter

问题描述

我试图通过Postman调用Put方法并且总是收到错误：405 Method Not Allow和Message：请求的资源不支持http方法'PUT'。

I was trying to call the Put method through Postman and always getting error:
"405 Method Not Allow" and "Message": "The requested resource does not support http method 'PUT'."

我正在使用DocumentDB和C＃。这是我的代码：

I'm using DocumentDB and C#. Here is my code:

[Route("multilanguage/Resources/{id}/{Language}")]
[HttpPut]
public async Task<IHttpActionResult> UpdateResource(string Id, string Language, string text)
{
    client = new DocumentClient(new Uri(EndPoint), AuthKey);
    var collectionLink = UriFactory.CreateDocumentCollectionUri(DatabaseId, CollectionId);

    var query = new SqlQuerySpec("SELECT * FROM MultiLanguage as m where m.id = @pmId", 
    new SqlParameterCollection(new SqlParameter[] { new SqlParameter { Name = "@pmId", Value = Id } }));

    Document doc = client.CreateDocumentQuery<Document>(
            collectionLink, query).AsEnumerable().FirstOrDefault();

    List<Models.Translations> d = doc.GetPropertyValue<List<Models.Translations>>("Translations");
    Models.Translations temp = d.Find(p => p.Language == Language);

    temp.Content = text;
    temp.LastModified = DateTimeOffset.Now;
    temp.ModifiedBy = "admin";
    doc.SetPropertyValue("Translations", d);

    Document updated = await client.ReplaceDocumentAsync(doc);

    return Ok();
}

当我通过Postman调用Put方法时，我称之为 http：// localhost：XXXX / multilanguage / resources / 2 / En 。 2和En是我代码中的前两个参数。我还使用x-www-form-urlencoded类型在Postman请求Body中指定text参数值：key = text，value = Test！这个put方法假设将temp.Content值更新为Test！。但是，它始终因上面提到的错误而失败。


我在这里错过了什么吗？

When I call the Put method throught Postman, I call "http://localhost:XXXX/multilanguage/resources/2/En". "2" and "En" are the first two parameters in my code. And I also specify the "text" parameter value in the Postman request Body with x-www-form-urlencoded type: key = text, value = Test! This put method suppose to update the temp.Content value to "Test!". However, it always failed with the error I mentioned above.

Did I miss anything here?

推荐答案

执行PUT时出现405错误对web api的请求是一个众所周知的主题。您可以在此<找到许多解决方案/ a>或这个 SO题。

The 405 error when performing a PUT request to web api is a well known topic. You can find many solutions in this or this SO question.

对于控制器的设计：

PUT设计有一个正文，就像POST一样在你的情况下
你应该发送身体中的所有参数。

PUT are designed to have a body, just like POST and in your case you should send all parameters in the body instead.

您应该创建一个包含要发送到服务器的对象的类：

You should create a class which contains the objects you want to send to the server:

public class resourceClass
{
    public string Id { get; set; }
    public string Language { get; set; }
    public string text { get; set; }
}

然后指定没有属性路由的路由并从请求中获取对象正文

Then specify the route without the attribute routing and get the object from the request body

[Route("multilanguage/Resources/PutResource")]
[HttpPut]
public async Task<IHttpActionResult> UpdateResource([FromBody] resourceClass obj)
{
    client = new DocumentClient(new Uri(EndPoint), AuthKey);
    var collectionLink = UriFactory.CreateDocumentCollectionUri(DatabaseId, CollectionId);

    var query = new SqlQuerySpec("SELECT * FROM MultiLanguage as m where m.id = @pmId", 
    new SqlParameterCollection(new SqlParameter[] { new SqlParameter { Name = "@pmId", Value = Id } }));

    Document doc = client.CreateDocumentQuery<Document>(
            collectionLink, query).AsEnumerable().FirstOrDefault();

    List<Models.Translations> d = doc.GetPropertyValue<List<Models.Translations>>("Translations");
    Models.Translations temp = d.Find(p => p.Language == Language);

    temp.Content = text;
    temp.LastModified = DateTimeOffset.Now;
    temp.ModifiedBy = "admin";
    doc.SetPropertyValue("Translations", d);

    Document updated = await client.ReplaceDocumentAsync(doc);

    return Ok();
}

从客户端您可以将对象添加到Content-Type的PUT请求中application / json喜欢这个

From the client you could add an object to the PUT request of Content-Type application/json like this

var data = {
    Id: clientId,
    Language: clientLanguage,
    text: clientText
};

在将json添加到http请求时，不要忘记对json进行字符串化

Don't forget to stringify the json when adding it to the http request

data: JSON.stringify(data),

然后将通过 http：// localhost：XXXX / multilanguage访问PUT控制器/资源/ putresource 。
