send()

Description​

Sends a necessary HTTP request to the server and returns a promise with or without data depending on the request

All requests to the server are made with the send() method which is a part of the RestDataProvider service.

Usage​

send(
    url: string,
    method: "GET" | "POST" | "PUT" | "DELETE" | string,
    data?: object,
    headers?: object,
): Promise<obj[]>

Parameters​

NameTypeDescription
urlstringRequired. A path to the server where a request is sent to.
methodstringRequired. An HTTP method type (Get, Post, Put, Delete)
dataobjectOptional. Parameters that are sent to the server. By default, parameters of the fired event are sent. But you are free to add additional parameters with the custom object.
headersobjectOptional. A default header is the Content-Type header set to application/json. More optional headers can be added with the customHeaders parameter. See the example below.

Returns​

The method returns the promise object with or without data depending on the request.

A promise is returned in response to the success request status. In case of the failed request (response.status == 500), an exception with an error text is thrown.

Examples​

The following examples demonstrate how to add more headers to the send() method.

const customHeaders = {
    "Authorization": "Bearer",
    "Custom header": "some value",
};

api.intercept("add-row", obj => {
    restDataProvider.send("", "POST", obj, customHeaders);
});
