Uri字符串太长-对于我的POST方法的输入参数

Question

I use fiddler to call my method, and for small strings it works perfectly. However, my input parameter may be the content of a 250 MB file.

Here's how I call it:

POST

http://localhost:23234/api/myfiles

User-Agent: Fiddler
Host: localhost:23234
Content-Type: application/json
Content-Length: 317210

And in the Request Body part, I have the content of a file which has 5.000 lines.

The method isn't getting hit. Instead, I get error 500, and the error messsage is: The Uri string is too long.

What can I do to make this work?

Answer 1

If you are hosting your API in IIS you should increase the maximum allowed request size (which by default is 4MB) by adding the following to your web.config:

<system.web>
    <!-- The value is in KB -->
    <httpRuntime maxRequestLength="1048576" />
</system.web>

and if you are using Integrated pipeline mode:

<system.webServer>
    <security>
        <requestFiltering>                          
            <!-- The value is in bytes -->
            <requestLimits maxAllowedContentLength="1073741824" />
        </requestFiltering>
    </security>
</system.webServer>

This will allow requests of 1GB to be sent.

Also you seem to have set the Content-Type to application/json so you should make sure that you are POSTing a valid JSON payload. Last but not least, ensure that you have selected POST in the Fiddler combobox with the verbs (the default is GET).
