Is a very simple example, but how also won't return JSON,
Environment: the.net 5.0 webapi

First to Startup file

Public void ConfigureServices (IServiceCollection services)
{
services.AddControllers();
}

Public void the Configure (IApplicationBuilder app, IWebHostEnvironment env)
{
If (env. IsDevelopment ())
{
App. UseDeveloperExceptionPage ();
}
App. UseHttpsRedirection ();
App. UseDefaultFiles ();
App. UseRouting ();
App. UseStaticFiles ();

App. UseEndpoints (endpoints=& gt;
{
Endpoints. MapControllers ();

});
}


And then the controller
[HttpGet]
Public stringGet ()
{
Return XXX. ToJson (); Here in directing a conversion of data, debugging is normal json structure ok
}

But running F12 found out is the text of the content-type is text/plan

Then add [Produces the controller (" application/json ")], was transformed

But json is received after forced to escape the json, can use


[HttpGet]
Public JsonResult the Get ()
{

Return new JsonResult (xxxObject);//xxxObject class object is the original
}


Try to find is indeed a json, but the json object is empty, only a large number, and {}

Then try to return objects directly

[HttpGet]
Public xxxObjectGet ()
{

Return xxxObject;//xxxObject class object is the original
}

Find it empty and JsonResult, json {}

Seek advice on how to use the.net 5 to create a simple get request, can return the json,

Thank you, I feel so can achieve a simple function, some depressed,

On the Internet looking for example is essentially a few years ago WEB Form, with no

Thank you,

Try

 

[httpGet] 
Public dynamic Test () 
{
Return new {id=1}; 
}

 public string the Get () 
{
Return JsonConvert. SerializeObject (result); 
} 
//receipt of each other, JsonConvert. DeserializeObject
