how to custom request method and params for GeoJSONLayer

Question

we can only use method of get and a url to get GeoJSON data for GeoJSONLayer,

It's too inflexible.

if params is too long，

there will be problems.

i want to load a GeoJSONLayer by GeoJSON data by other custom request ，

how i can i do？

or how  can i custom request method and params by official method?

You don't have to do anything. The GeoJSONLayer uses esriRequet to fetch the data. If your url query params are more 2000 characters, the esriRequest switches to post automatically. So the GeoJSONLayer will fetch the data no matter how long the url is.

Sorry I didn't read the document carefully enough .Is there a way to specify the request method?

Hi there,

The esriRequest automatically switches to POST if URL is too long. The maxUrlLength controls when requests switch to POST. So you don't have to anything. 🙂

Hope this helps,
