頭像修改功能

準(zhǔn)備

后端接口

  • 添加pom.xml依賴
<dependency>
    <groupId>com.aliyun.oss</groupId>
    <artifactId>aliyun-sdk-oss</artifactId>
    <version>2.8.3</version>
</dependency>
  • 測(cè)試阿里云OSS上傳功能 AliOSSTest
public class AliOSSTest {
    public static void main(String[] args) {
        // Endpoint以杭州為例，其它Region請(qǐng)按實(shí)際情況填寫。
        String endpoint = "http://oss-cn-hangzhou.aliyuncs.com";
        // 阿里云主賬號(hào)AccessKey擁有所有API的訪問權(quán)限，風(fēng)險(xiǎn)很高
        String accessKeyId = "****";
        String accessKeySecret = "****";
        String bucketName = "****";
        String filedir = "avatar/";
        String fileKey = "hello.jpg";
        // 創(chuàng)建OSSClient實(shí)例
        OSSClient ossClient = new OSSClient(endpoint, accessKeyId, accessKeySecret);
        // 上傳文件
        PutObjectResult putResult = ossClient.putObject(bucketName, filedir + fileKey, new File("D:\\bg.jpg"));
        //時(shí)間戳
        Date expiration = new Date(new Date().getTime() + 3600l * 1000 * 24 * 365 * 10);
        // 生成URL
        URL url = ossClient.generatePresignedUrl(bucketName, filedir + fileKey, expiration);
        System.out.println(url);
        ossClient.shutdown();
    }
}
  • 編寫上傳接口程序，然后用swagger測(cè)試
package com.soft1721.jianyue.api.controller;

import com.aliyun.oss.OSSClient;
import com.aliyun.oss.model.PutObjectResult;
import com.soft1721.jianyue.api.util.ResponseResult;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;

import java.io.File;
import java.io.IOException;
import java.net.URL;
import java.util.Date;
import java.util.UUID;

@RestController
@RequestMapping(value = "/api")
public class UploadController {
    @PostMapping("/avatar/upload")
    public String ossUpload(@RequestParam("file") MultipartFile sourceFile) {
        String endpoint = "http://oss-cn-hangzhou.aliyuncs.com";
        String accessKeyId = "***";
        String accessKeySecret = "***";
        String bucketName = "***";
        String filedir = "avatar/";
        // 獲取源文件名
        String fileName = sourceFile.getOriginalFilename();
        // 獲取源文件名后綴
        String suffix = fileName.substring(fileName.lastIndexOf("."));
        //uuid生成主文件名
        String prefix = UUID.randomUUID().toString();
        //新文件名
        String newFileName = prefix + suffix;
        //File類型的臨時(shí)文件
        File tempFile = null;
        try {
            //創(chuàng)建臨時(shí)文件，用uuid主文件名+原后綴名
            tempFile = File.createTempFile(prefix, prefix);
            // MultipartFile轉(zhuǎn)成File
            sourceFile.transferTo(tempFile);
        } catch (IOException e) {
            e.printStackTrace();
        }
        OSSClient ossClient = new OSSClient(endpoint, accessKeyId, accessKeySecret);
        ossClient.putObject(bucketName, filedir + newFileName, tempFile);
        Date expiration = new Date(new Date().getTime() + 3600l * 1000 * 24 * 365 * 10);
        // 生成URL
        URL url = ossClient.generatePresignedUrl(bucketName, filedir + newFileName, expiration);
        ossClient.shutdown();
        //URL返回給客戶端
        return url.toString();
    }
}
  • 編寫修改個(gè)人頭像的接口，并且用JUnit、swagger測(cè)試
    省略mapper層、service層，自行完成并進(jìn)行單元測(cè)試
    UserController類的修改用戶頭像接口
@PostMapping("/avatar")
public String ossUpload(@RequestParam("file") MultipartFile sourceFile,@RequestParam("userId") int userId) {
    String endpoint = "http://oss-cn-hangzhou.aliyuncs.com";
    String accessKeyId = "***";
    String accessKeySecret = "***";
    String bucketName = "***";
    String filedir = "avatar/";
    // 獲取文件名
    String fileName = sourceFile.getOriginalFilename();
    // 獲取文件后綴
    String suffix = fileName.substring(fileName.lastIndexOf("."));
    //uuid生成主文件名
    String prefix = UUID.randomUUID().toString();
    String newFileName = prefix + suffix;
    File tempFile = null;
    try {
        //創(chuàng)建臨時(shí)文件
        tempFile = File.createTempFile(prefix, prefix);
        // MultipartFile to File
        sourceFile.transferTo(tempFile);
    } catch (IOException e) {
        e.printStackTrace();
    }
    OSSClient ossClient = new OSSClient(endpoint, accessKeyId, accessKeySecret);
    ossClient.putObject(bucketName, filedir + newFileName, tempFile);
    Date expiration = new Date(new Date().getTime() + 3600l * 1000 * 24 * 365 * 10);
    // 生成URL
    URL url = ossClient.generatePresignedUrl(bucketName, filedir + newFileName, expiration);
    ossClient.shutdown();
    //根據(jù)userId查詢出原始用戶數(shù)據(jù)
    User user = userService.getUserById(userId);
    //更新頭像屬性
    user.setAvatar(url.toString());
    //修改用戶信息并持久化
    userService.updateUser(user);
    //將頭像鏈接返回給客戶端，以便實(shí)時(shí)預(yù)覽
    return url.toString();
}

前端

  • setting頁(yè)面點(diǎn)擊用戶資料跳轉(zhuǎn)到user_info頁(yè)面，pages.json中注冊(cè)新頁(yè)面
