Additional Information
The Web Map Service (WMS) spec never standardized XML encoding for the post body, so GetMap requests as XML is not supported when sent as POST since the XML may be different for each server. Regarding always sending GetMap requests as GET, we decided against that as well, since we do not want to break existing layers where the server responds correctly. As an alternative, this request interceptor always makes a GET request: esriConfig.request.interceptors.push({ urls: "https://host/path", async before(params) { if (params.requestOptions.responseType === "image") { const url = new URL(params.url); url.search = new URLSearchParams([ ...Array.from(url.searchParams.entries()), ...Object.entries(params.requestOptions.query || {}) ]).toString(); const img = new Image() img.crossOrigin = "anonymous"; img.src = url.href; await img.decode() return img; } } });Steps to Reproduce
