Missing part of the response header,about easywebapp/koajax

Which platform are you using? Web browsers or Node.js? It aims to find out which standard API is invoked:

Lines 183 to 187 in 8a8b3cc

    
           export function request<B>(options: Request): RequestResult<B> { 
        
               return typeof globalThis.XMLHttpRequest === 'function' 
        
                   ? requestXHR<B>(options) 
        
                   : { response: requestFetch<B>(options) }; 
        
           }

Could you give me an example API to test the request？

https://stackoverflow.com/questions/8945587/xmlhttprequest-getallresponseheaders-not-returning-all-the-headers

So this issue is the duty of your API server to resolve.

Web browsers.

Now I need to record the time of a http request in the browser, so I need to get the Data value of the response header. When I print the corresponding value, I can only get Content-Length and Content-Type.
Oddly enough, I can see Data in the browser's debugging tool, and I'm not sure if the library cropped the response header.

Now I need to record the time of a http request in the browser, so I need to get the Data value of the response header.

Just write a Logger middleware:

new HTTPClient().use(async ({ request: { path } }, next) => {
    const title = `HTTP request: ${path}`;

    console.time(title);

    await next();

    console.timeEnd(title);
});

Oddly enough, I can see Data in the browser's debugging tool, and I'm not sure if the library cropped the response header.

I never crop standard HTTP headers:

KoAJAX/source/HTTPRequest.ts

Line 107 in 8a8b3cc

headers: parseHeaders(request.getAllResponseHeaders()),

KoAJAX/source/HTTPRequest.ts

Lines 66 to 78 in 8a8b3cc

    
           export function parseHeaders(raw: string): Response['headers'] { 
        
               return Object.fromEntries( 
        
                   Array.from( 
        
                       raw.trim().matchAll(/^([\w-]+):\s*(.*)/gm), 
        
                       ([_, key, value]) => { 
        
                           key = key.replace(/(^[a-z]|-[a-z])/g, char => 
        
                               char.toUpperCase() 
        
                           ); 
        
                           return [key, headerParser[key]?.(value) ?? value]; 
        
                       } 
        
                   ) 
        
               );
