JS access to WebService "no permission" test form can only be used for requests from local computers"

At work, I found that the WebService on the local computer called by JS is displayed normally. When someone accesses my machine, it prompts "no permission" and no data is available! Try to publish it to the server. When you deploy a website and assign the ISAPI execution permission to the website, no such problem will be prompted!
To test whether the WebService is released normally, the system prompts "the test form can only be used for requests from the Local Computer" when calling the web service. httpget and httppost are not configured in config. The configuration in <system. Web> is as follows:
<WebServices>
<Protocols>
<Add name = "httppost"/>
<Add name = "httpget"/>
</Protocols>
</WebServices>
After configuration, you can directly call the WebService on the server on other machines for testing.
