How to implement stock quotes and fund statistics in uniapp

uniapp is a cross-platform application framework developed based on Vue.js, which can quickly and efficiently develop mobile applications. It is a very common requirement to implement stock quotes and fund statistics in uniapp. Specific code examples will be given below to help you realize this function.

First, we need to obtain stock market data. In uniapp, you can obtain real-time stock market data by calling third-party APIs. The following is a code example for obtaining stock quotes:

// 导入uni-app的网络请求模块
import { request } from '@flyio/uni-app'

// 获取股票行情数据
export function getStockQuotes() {
  return new Promise((resolve, reject) => {
    request({
      method: 'GET',
      url: 'http://api.stockquotes.com/quotes',
      success: (res) => {
        resolve(res.data)
      },
      fail: (err) => {
        reject(err)
      }
    })
  })
}

In the above example, the @flyio/uni-app module of uni-app is used to send network requests and obtain stock quotes data. The specific request method and URL will be modified according to the actual situation.

Next, we need to implement the function of fund statistics. Fund statistics mainly count users' assets or transaction records, and perform corresponding calculations and displays. The following is a simple code example of fund statistics:

// 获取用户资产
export function getUserAssets() {
  return new Promise((resolve, reject) => {
    request({
      method: 'GET',
      url: 'http://api.stockquotes.com/user/assets',
      success: (res) => {
        resolve(res.data)
      },
      fail: (err) => {
        reject(err)
      }
    })
  })
}

// 获取用户交易记录
export function getUserTransactions() {
  return new Promise((resolve, reject) => {
    request({
      method: 'GET',
      url: 'http://api.stockquotes.com/user/transactions',
      success: (res) => {
        resolve(res.data)
      },
      fail: (err) => {
        reject(err)
      }
    })
  })
}

// 计算用户资金统计
export function calculateUserStatistics() {
  return new Promise((resolve, reject) => {
    Promise.all([getUserAssets(), getUserTransactions()])
      .then(([assets, transactions]) => {
        // 进行资金统计计算
        let totalAssets = 0
        let totalTransactions = 0

        // 对资产进行统计计算
        assets.forEach(asset => {
          totalAssets += asset.value
        })

        // 对交易记录进行统计计算
        transactions.forEach(transaction => {
          totalTransactions += transaction.amount
        })

        resolve({
          totalAssets,
          totalTransactions
        })
      })
      .catch(err => {
        reject(err)
      })
  })
}

In the above example, we use the getUserAssets() and getUserTransactions() functions to obtain the user's assets and transaction records respectively. Then use the Promise.all() function to merge the two asynchronous requests into a Promise object, and use the .then() and .catch() methods to handle the return result or error. In the calculateUserStatistics() function, we perform statistical calculations on the user's assets and transaction records and return the calculation results.

Finally, use the above function in the Vue component to display stock quotes and financial statistics:

<template>
  <div>
    <h1>股票行情</h1>
    <ul>
      <li v-for="quote in stockQuotes" :key="quote.id">
        {{quote.name}} - {{quote.price}}
      </li>
    </ul>
    <h1>资金统计</h1>
    <p>总资产：{{statistics.totalAssets}}</p>
    <p>交易总额：{{statistics.totalTransactions}}</p>
  </div>
</template>

<script>
import { getStockQuotes, calculateUserStatistics } from '@/api'

export default {
  data() {
    return {
      stockQuotes: [],
      statistics: {}
    }
  },
  mounted() {
    // 获取股票行情数据
    getStockQuotes()
      .then(data => {
        this.stockQuotes = data
      })
      .catch(err => {
        console.error(err)
      })

    // 获取用户资金统计
    calculateUserStatistics()
      .then(statistics => {
        this.statistics = statistics
      })
      .catch(err => {
        console.error(err)
      })
  }
}
</script>

In the above example, we obtain the stock quotes data by calling the getStockQuotes() function, and Save the data in stockQuotes array. Then call the calculateUserStatistics() function to obtain user fund statistics and save the data in the statistics object. Finally, use v-for instructions and data binding in the HTML template to display stock quotes and financial statistics.

The above are specific code examples to implement stock quotes and fund statistics in uniapp. Through the above examples, we can see that uniapp provides very convenient network request and data binding functions, which can help us quickly implement complex functions. I hope to be helpful!
