post request - errors

Hi Vani_metamicro ,

SPHttpClient class getWebUrlFromRequestUrl(requestUrl) method attempts to infer the SPWeb URL associated with the provided REST URL, by looking for common SharePoint path components such as "_api", "_layouts", or "_vit_bin". So, if the requestUrl is "http://example.com/_layouts/service", the returned URL would be "http://example.com".

But here, the url generated is 

const postURl = "

";

So, it could not infer any SPWebUrl from it. So, instead of SPHttpClient, use HttpClient class. Also, the flow will be triggered by a HttpRequest.

The modified code is:

private _getListData(): Promise<any> {
const spOpts:IHttpClientOptions= {headers: { 'Content-Type': 'value' }, body:"value" };
const postURl = "

";
return this.context.HttpClient
.post(postURl, HttpClient.configurations.v1, spOpts)
.then((response: any) => {
console.log('Post request is success', response);
return response.json();
});
}
