How to set ip address in uniapp

With the popularity and development of mobile Internet, the demand for mobile applications is increasing, and developers are also looking for more efficient and convenient development methods. As a cross-platform application development framework, UniApp can quickly develop applications that run on multiple platforms such as iOS, Android, and H5 at the same time.

During the development process, UniApp provides a function to use Websocket for data transmission. In this case, we need to set up a server for transmitting data, and we need to set the IP address of the server. In this article, I will explain in detail how to set the IP address in UniApp.

In UniApp, we can choose to use uni-ajax components to achieve data interaction with the server. When using this component for data transmission, we need to create an ajax instance. In this example, we need to set the server's address. The following is a simple example code:

import Vue from 'vue'
import App from '@/App'
import uView from 'uview-ui'

Vue.use(uView)

Vue.prototype.$ajax = function(url, method, data) {
  return new Promise((resolve, reject) => {
    uni.request({
      url: 'http://your_server_ip:your_server_port' + url,
      method: method,
      data: data,
      header: {
        'Content-Type': 'application/json'
      },
      success: (res) => {
        resolve(res.data)
      },
      fail: (err) => {
        reject(err)
      }
    })
  })
}

Vue.config.productionTip = false

App.mpType = 'app'

const app = new Vue({
  ...App,
})
app.$mount()

In this code, we can see that in the uni.request() method, the address of the server needs to be set. If you are using a local development environment, you need to set the server address to your local IP address.

In UniApp, we can also use the uni-ws component to implement Websocket communication. When using this component for data transmission, we also need to set the IP address of the server. The following is a simple example code:

import Vue from 'vue'
import App from '@/App'
import uView from 'uview-ui'

Vue.use(uView)

Vue.prototype.$ws = function(url) {
  return new Promise((resolve, reject) => {
    uni.connectSocket({
      url: 'ws://your_server_ip:your_server_port' + url,
      success: () => {
        resolve()
      },
      fail: (err) => {
        reject(err)
      }
    })
  })
}

Vue.config.productionTip = false

App.mpType = 'app'

const app = new Vue({
  ...App,
})
app.$mount()

In this code, we can see that in the uni.connectSocket() method, the IP address of the server also needs to be set.

In this article, we introduce how to set the IP address in UniApp. Whether you are using the uni-ajax component or the uni-ws component, setting the IP address of the server is necessary. In actual development, please set it according to your specific situation.
