Read Channel/s

To read existing channel records you will need to make a TLS request to the OpenHIM API for the below method and endpoint.

Read all channels

Method: GET

Endpoint: {openhim_url}:8080/channels

Read a specific channel

Method: GET

Endpoint: {openhim_url}:8080/channels/:channelId

Example

Note: In the examples below, we are using the token authentication type to authenticate requests

Before we can send our request to the OpenHIM API we need to ensure that we construct our valid HTTP headers to successfully authenticate with the OpenHIM API.

NodeJS

Copy the below code at the bottom of your nodejs script that handles the authentication of the OpenHIM headers as described in the authentication section.

Replace the openhimOptions values with the correct implementation details

// append below code to the "openhim-api.js" script containing the authentication methods.

// This is described within the authentication section

(async () => {

const openhimOptions = {

apiURL: 'https://localhost:8080',

apiEndpoint: '/channels/channelId',

username: '[email protected]',

password: 'openhim-password',

rejectUnauthorized: false

}

const headers = await genAuthHeaders(openhimOptions)

const options = { method: 'GET',

url: `${openhimOptions.apiURL}${openhimOptions.apiEndpoint}`,

rejectUnauthorized: openhimOptions.rejectUnauthorized,

headers: headers

}

request(options, (error, response, body) => {

if (error) throw new Error(error)

console.log({

statusCode: response.statusCode,

body

})

})

})()

Bash

Ensure that you have created your bash script to construct the HTTP authentication headers and send the request to the OpenHIM API as described in the authentication section.

Execute the below command in your terminal where the file is located with the required arguments. Replace the placeholder arguments with the correct implementation details.

./openhim-api.sh [email protected] openhim-password -v https://localhost:8080/channels/channelId

The response status code will be 200 if successful.
