从ASP.NET页面方法增加最大响应大小

Question

I've got a page method on an ASPX page that gets called by a jQuery AJAX POST request. When I try to return too many results, the request fails. Is there a web.config setting or class attribute I can use to increase the default maximum response size?

Answer 1

I am assuming you are returning JSON?

You can adjust the JSON response size in the web.config with:

<configuration>
    <system.web.extensions>
        <scripting>  
             <webServices>                                                   
                 <jsonSerialization maxJsonLength="1000000" />                 
             </webServices>
        </scripting>
    </system.web.extensions>
</configuration>

Doing a quick search, it looks like the default size is 102400.

maxJsonLength Optional attribute.

Configures the maximum length of the JSON string (the maximum number of UTF-8 characters).

The default length is 102400.
