You mentioned you're using Ruby on Rails as a backend. You didn't post the code for the relevant method, but my guess is that it looks something like this:

<pre><code>def create
 post = Post.create params[:post]
 respond_to do |format|
 format.json { render :json =&gt; post }
 end
end
</code></pre>

Change it to:

<pre><code>def create
 post = Post.create params[:post])
 render :json =&gt; post
end
</code></pre>

And it will solve your problem. It worked for me :)

You can also receive a 406 response when invalid cookies are stored or referenced in the browser - for example, when running a Rails server in Dev mode locally.

If you happened to run two different projects on the same port, the browser might reference a cookie from a different localhost session.

This has happened to me...tripped me up for a minute. Looking in browser > Developer Mode > Network showed it.

blocks|key|1922252|text|“有时”，这可能意味着服务器有一个内部错误，并希望以错误消息响应(例如:+500，JSON有效负载)，但由于请求头部没有说明它接受JSON，所以它返回一个406。去想一想。(在本例中:+spring+boot+webapp)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1922253|在这种情况下，您的操作确实失败了。但失败消息被另一个消息掩盖了。|1922254|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

"Sometimes" this can mean that the server had an internal error, and wanted to respond with an error message (ex: 500 with JSON payload) but since the request headers didn't say it accepted JSON, it returns a 406 instead. Go figure. (in this case: spring boot webapp).

In which case, your operation did fail. But the failure message was obscured by another.

blocks|key|1922301|text|如果您使用的是'request.js‘，则可以使用以下内容：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1922302|var+options+=+{

In my case for a API in .NET-Core, the api is set to work with XML (by default is set to response with JSON), so I add this annotation in my Controller : 

<pre><code>[Produces("application/xml")]

Thank you for putting me on the path !

In my Ruby on Rails application I tried to upload an image through the POSTMAN <a href="http://en.wikipedia.org/wiki/Representational_State_Transfer">REST</a> client in <a href="http://en.wikipedia.org/wiki/Base64">Base64</a> format. When I POST the image I am getting a 406 Not Acceptable Response. When I checked my database, the image was there and was successfully saved.

What is the reason for this error, is there anything I need to specify in my header?

My request:

URL --- <code>http://localhost:3000/exercises.json</code>

Header:

<pre><code>Content-Type - application/json
</code></pre>

Raw data:

<pre><code>{
 "exercise": {
 "subbodypart_ids": [
 "1",
 "2"
 ],
 "name": "Exercise14"
 },
 "image_file_name": "Pressurebar Above.jpg",
 "image":"******base64 Format*******"
}
</code></pre>

What is "406-Not Acceptable Response" in HTTP?

数据库

服务器

JSON

在我的Ruby on Rails应用程序中，我尝试通过POSTMAN 客户端上传格式的图像。当我发布这张图片时，我得到了406不可接受的回复。当我检查我的数据库时，图像就在那里并且被成功地保存了。这个错误的原因是什么，我需要在我的头中指定什么吗？我的要求是：URL - http://localhost:3000/exe...
