Http response Truncated

Question

I deployed an application under the IIS site of Sharepoint as the API site of my Web Part, as shown in the figure

But when I request data from this site, I often find that the requested body is truncated. There is no rule to summarize (same request)
However, when I did not place the API site under the Sharepoint site, this problem did not occur. I would like to ask whether the Sharepoint site has a length or character limit for this kind of data request?
The truncation situation is shown in the figure
Looking forward to your reply, thank you

Answer 1

I suggest you use a packet capture tool(like fidder) to capture the request,then compare the difference between the fetched return value and the return value on the page.
