另一篇請求接口簡單封裝在api下的index.js

本片資源下載地址

本片封裝了post get put請求，重點在request.js文件

1.新增四個文件

2.根目錄下的utils下的request.js封裝uni.request()請求

注意 ：需要根據自己接口的 statusCode 狀態碼 、數據狀態碼 return_code 和提示信息 return_message 做對應替換
需要更改公共地址
需要注意store的token獲取
需要注意 封裝了get post put請求 需要其他的請求自行繼續封裝

3.pages/api/modules.js
注意：api下 一個模塊js文件 存放一個模塊的接口方法

/*data為 {}請求參數，params為 {}, 最后更改為url傳參opts為 {loading: false,hasToken: false}其中loading為false不顯示loading框hasToken為false, 請求不需要tokenreturn $https.get({url,data,params,...opts})return $https.post({url,data,params,...opts})*/ import { $https } from '../../utils/request' // 獲取學生列表 export function getStudentList(params) {return $https.get({url: `main/stuWork/answersBySerial`,params,loading: false,}) } // 獲取練習下題目信息 export function getQuestionByWorkId(params) {return $https.get({url: `main/work/queStatus/${params.workId}`,}) } // 獲取練習下所有題目批改信息 暫不使用 export function getQuestionCorrectByWorkId(params) {return $https.get({url: 'main/resource/getQuestion',params,}) }// 提交單道題目批改結果 export function submitCorrectAnswer(data) {return $https.post({url: `main/correction/subCorrResult`,data,loading: false,}) }// 動態id獲取練習信息 export function getExerciseInfo(id) {return $https.get(`main/interaction/start/${id}`) } // 直接get獲取 export function getProductcategory() {return $https.get({url: `api/v1/accident/productcategory/list`,}) } // get參數獲取 export function getInsurancecompany(params) {return $https.get({url: `api/v1/accident/insurancecompany/list`,params,}) } // post參數請求 export function postInsurance(data) {return $https.post({url: `api/v1/accident/insurance/list`,data,}) }

4.請求vue頁面

5.成功接口請求：

6.失敗接口：
404提示：

接口調用成功200 但是data的狀態碼返回異常 做提示:
