[WebAPI] The webapi receives the json string of the post

[Copy link]

WebAPI is actually very powerful, I saw many articles on the Internet, when receiving the JSON string of POST, it is all received with String,


Then, why bother with the object。。。。。。


I think webapi can directly convert json strings into objects, otherwise webapi has no meaning of existence...


The code is as follows:


WebAPI Controller:




The json string we posted looks like this:

{"name":"Architecthttp://www.itsvse.com","age":5}


Notes:

When we post the json string to the interface, we need to set the request header: "Content-Type:application/json"

Setting: Content-Type:x-www-form-urlencoded The background object will be empty and will not be received at all

Setting: Content-Type:text/plain will directly report the following error:

{
    "Message": "An error occurred." ,
    "ExceptionMessage": "Unable to read an object of type "apitest" from a content with media type "text/plain" with no MediaTypeFormatter available. ",
    "ExceptionType": "System.InvalidOperationException",
    "StackTrace": " xxx"
}

Attached is a model validation filter for the webapi interface



Note that if the parameter passed by the reference type is empty, the model validation will pass! Please note that it is empty
