The POST method cannot be used in Uniapp. In most cases, it is because the uni-ajax plug-in is not installed. The uni-ajax plug-in is a plug-in for sending HTTP requests in Uniapp. You can use this plug-in to send HTTP requests very conveniently.

The second step, after installing the uni-ajax plug-in, you need to introduce and register the uni-ajax plug-in in the app.vue file. Add the following code in the app.vue file.

import Vue from 'vue'
import App from './App'

import uniAjax from './uni-ajax/uni-ajax.js'
Vue.prototype.$uniAjax = uniAjax

Vue.config.productionTip = false

App.mpType = 'app'

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

The third step is to send HTTP requests through this.$uniAjax.post() method on any page. An example is as follows:

export default {
  data () {
    return {

    }
  },
  methods: {
    postTest () {
      this.$uniAjax.post('https://api.apiopen.top/getJoke?page=1&count=2&type=video', {
        data: ''
      }, function(res) {

  }
}
