Multiple interceptors arcgis 4.x

Hi,

Arcgis 4.x JSAPI

esriConfig.request.interceptors support multiple interceptors?

It takes an array of interceptors, each can intercept a different URL, so yes, it can.

You need to specify the "urls" string so the interceptor knows which URL should be intercepted. the way you have it set up the "urls" is null or undefined, so the first one overwrites the second.

Thanks you! it's working!

Apparently Arcgis Experience Builder already add interceptor at file

client\dist\jimu-arcgis\index.js (it's built minified)

(e=re.request.interceptors)||void 0===e||e.push({after:e=>{var t,i;(null===(t=null==e?void 0:e.url)||void 0===t?void 0:t.indexOf("/rest/info"))&&(null===(i=null==e?void 0:e.data)||void 0===i?void 0:i.owningSystemUrl)&&this.registOAuthInfo(e.data.owningSystemUrl)}}),

but they add interceptor without urls property

so even if I add urls

esriConfig.request.interceptors.push({ urls: /FeatureServer\/\d+/, after: function (response) { response.data.supportedQueryFormats = "JSON"; } });

It's not intercept.

I tried to add urls to the first interceptor

esriConfig.request.interceptors[0].urls = /.*?/

esriConfig.request.interceptors[0].urls = /.*/

also not working

But

when tried

esriConfig.request.interceptors[0].urls = /blalba.*/

It's seems like if hit the first interceptor it's not continue to the second one.

Meanwhile I do

esriConfig.request.interceptors.push({ urls: /FeatureServer\/\d+/, after: function (response) { debugger; response.data.supportedQueryFormats = "JSON"; } }); esriConfig.request.interceptors.reverse();

Any suggestions?
