App数据服务对象设计与实现
根据业务需求分析及API接口文档，需要构建如下数据服务对象：
AccountManagerUserManagerMessageManagerFriendManager
构建URLConfig模块
const host = 'http://60.205.141.116:'
const port = 60004;
const registerURL = host+port+'/api/register';
const loginURL = host+port+'/api/login';
const createUserURL = host+port+'/api/createUser';
const postMessageURL = host+port+'/api/postMessage';
const deleteMessageURL = host+port+'/api/deleteMessage';
const followURL = host+port+'/api/follow';
const unFollowURL = host+port+'/api/unFollow';
const getFollowURL = host+port+'/api/getFollow';
const updateUserURL = host+port+'/api/updateUser';
const getUserURL = host+port+'/api/getUser';
const getMessageURL = host+port+'/api/getMessage';
const homeMessageURL = host+port+'/api/homeMessage';
const findUserURL = host+port+'/api/findUser';
const changePasswordURL = host+port+'/api/changePassword';
const imageBaseURL = host+port+'/resource/image/';
export {
registerURL,
loginURL,
changePasswordURL,
createUserURL,
updateUserURL,
getUserURL,
postMessageURL,
getMessageURL,
homeMessageURL,
deleteMessageURL,
findUserURL,
followURL,
unFollowURL,
getFollowURL,
imageBaseURL,
}
构建AccountManager
该数据服务对象提供以下数据功能：
- 注册
- 登录
- 修改密码
- 查询登录状态
- 登出
import {
loginURL,
registerURL,
changePasswordURL
} from './URLConfig';
import axios from 'axios';
class AccountManager {
async register(email,password){
try {
const res = await axios.post(registerURL,{
email,
password
});
const result = res.data;
if (result.success === true) {
localStorage.access_token = result.data.access_token;
}
return result;
} catch (error) {
return {
success:false,
errorMessage:'网络错误'
}
}
}
async login(email,password){
try {
const res = await axios.post(loginURL,{
email,
password
});
const result = res.data;
if (result.success === true) {
localStorage.access_token = result.data.access_token;
}
return result;
} catch (error) {
return {
success:false,
errorMessage:'网络错误'
}
}
}
async changePassword(old_password,new_password){
try {
const access_token = localStorage.access_token;
const res = await axios.post(changePasswordURL,{
access_token,
old_password,
new_password
});
const result = res.data;
return result;
} catch (error) {
return {
success:false,
errorMessage:'网络错误'
}
}
}
isLogin(){
if(localStorage.access_token === '' || !localStorage.access_token){
return false;
} else {
return true;
}
}
logout(){
localStorage.access_token = '';
}
}
export default new AccountManager();
构建UserManager
该数据服务对象提供以下功能：
- 创建用户信息
- 更新用户信息
- 获取用户信息
import {
createUserURL,
updateUserURL,
getUserURL,
} from './URLConfig';
import axios from 'axios';
class UserManager {
async createUser(nickname,sign,image){
try {
const access_token = localStorage.access_token;
const formData = new FormData();
formData.append('access_token',access_token);
formData.append('nickname',nickname);
formData.append('sign',sign);
formData.append('image',image.file);
const res = await axios({
url:createUserURL,
method:'POST',
data:formData,
headers: {'Content-Type': 'multipart/form-data'}
})
return res.data;
} catch (error) {
return {
success:false,
errorMessage:'网络错误'
}
}
}
async updateUser(userInfo){
try {
const access_token = localStorage.access_token;
const formData = new FormData();
formData.append('access_token',access_token);
if (userInfo.nickname) {
formData.append('nickname',userInfo.nickname);
}
if (userInfo.sign) {
formData.append('sign',userInfo.sign);
}
if (userInfo.image) {
formData.append('image',userInfo.image.file);
}
const res = await axios({
url:updateUserURL,
method:'POST',
data:formData,
headers: {'Content-Type': 'multipart/form-data'}
})
return res.data;
} catch (error) {
return {
success:false,
errorMessage:'网络错误'
}
}
}
async getUserInfo(userId = 0){
try {
const access_token = localStorage.access_token;
const res = await axios.post(getUserURL,{
access_token,
userId
})
return res.data;
} catch (error) {
return {
success:false,
errorMessage:'网络错误'
}
}
}
}
export default new UserManager();
构建MessageManager
该数据服务对象提供以下功能：
- 发送消息
- 删除消息
- 获取指定用户消息

import axios from 'axios';
import {
postMessageURL,
getMessageURL,
homeMessageURL,
deleteMessageURL,

class MessageManager {
async postMessage(content,images){
try {
const access_token = localStorage.access_token;
const formData = new FormData();
formData.append('access_token',access_token);
formData.append('content',content);
if (images) {
images.map((image,index)=>{
formData.append(`image${index+1}`,image.file);
return '';
})
}
const res = await axios({
url:postMessageURL,
method:'POST',
data:formData,
headers: {'Content-Type': 'multipart/form-data'}
})
return res.data;
} catch (error) {
return {
success:false,

async deleteMessage(messageId){
try {
const access_token = localStorage.access_token;
const res = await axios.post(deleteMessageURL,{

return {
success:false,
errorMessage:'网络错误'
}

async homeMessage(minId){
try {
const access_token = localStorage.access_token;

}
async getUserMessage(userId,minId){
try {
const access_token = localStorage.access_token;
const res = await axios.post(getMessageURL,{
access_token,

class FriendManager {
async findUser(nickname){
try {
const access_token = localStorage.access_token;

access_token,
nickname
})
return res.data;
} catch (error) {

}
}
export default new FriendManager();
