quperagent

Superagent like HTTP client for QML

Add to project:

Add quperagent.pri to your .pro file:

include(path/to/quperagent.pri)

And then import quperagent.js into your qml file:

import "qrc:/quperagent.js" as HTTPC

Usage:

HTTP requests:

a simple quperagent request can be look like the following:

        HTTPC.request()
        .get(`https://example.test`)
        .end((res) => {}, (err) => {});

end() function gets two callbacks to deliver success response or failure response and also quperagent will serialize response if possible. Each success response and failure response objects will have the following properties:

• status => HTTP response status
• text => HTTP raw response
• body => Serialized response, if content-type header of response equal to application/json

What about the other HTTP methods:

        HTTPC.request()
        .post(`https://example.test`)

        HTTPC.request()
        .put(`https://example.test`)

        HTTPC.request()
        .del(`https://example.test`)

Add headers to request:

You can use the set() method for adding headers to the request like the following, note that, quperagent will add application/json to the content-type if not any header set to the request:

        HTTPC.request()
        .post(`https://example.test`)
        .set({
                 "Content-type": "application/json",
                 "Authorization": `Basic `
             })
        .end((res) => {}, (err) => {});

Add query string to the request:

You can add a query string to the some HTTP request like GET and DELETE easily with the query() method:

        HTTPC.request()
        .get(`https://example.test`)
        .query({
                   "search": "foo",
                   "sort": "bar",
                   "groupby": ["foo", "bar"]
                })
        .end((res) => {}, (err) => {});

Also, you may need to send a raw query string in some cases, so you can pass a simple string to the query():

        HTTPC.request()
        .get(`https://example.test`)
        .query("search=foo&sort=bar&groupby=foo&groupby=bar")
        .end((res) => {}, (err) => {});

Send HTTP data on body:

You can send payload on request body by passing a javascript object to the send() method:

        HTTPC.request()
        .post(`https://example.test`)
        .send({
                   "search": "foo",
                   "sort": "bar"
                })
        .end((res) => {}, (err) => {});

ququperagent will serialized payload based on the content-type header automatically:

• if content-type set to the application/json then quperagent will send body as a JSON string
• if content-type set to the application/x-www-form-urlencoded then quperagent will send body as an url encoded data
• else, quperagent will send payload as a raw data
