1.图片选择后，路径已经存入list中：
data: {
images: [], //选择的图片
},
|
2.调用递归上传的方法：
wx.chooseImage({
var that = this
count: 9,
sizeType: ['original', 'compressed'],
sourceType: ['album', 'camera'],
success: function(res){
var successUp = 0; //成功，初始化为0
var failUp = 0; //失败，初始化为0
var length = that.data.images.length; //总共上传的数量
var count = 0; //第几张，初始化为0
var url = serverUrl + '/secondHand/uploadImg?id=' + secondHandId; //上传的接口
//调用上传图片的公共函数
that.uploadOneByOne(url, that.data.images, successUp, failUp, count, length);
},
});
|
3.递归上传方法：
/**
* 上传图片：递归的方式上传
* url:上传地址
* imgPaths：上传的图片列表
* successUp：上传成功的个数，初始化为0
* failUp：上传失败的个数，初始化为0
* count：第几张
* length：图片列表的长度
*/
uploadOneByOne(url, imgPaths, successUp, failUp, count, length) {
var that = this;
wx.uploadFile({
url: url, //上传地址地址
filePath: imgPaths[count],
name: "file", //后台接收的文件名
success: function(e) {
successUp++; //成功+1
},
fail: function(e) {
failUp++; //失败+1
},
complete: function(e) {
count++; //下一张
if (count == length) {
TODO: 上传完毕后跳转页面
wx.showToast({
title: '发布成功',
icon: 'success',
duration: 2000
})
}
else {
//递归调用，上传下一张
that.uploadOneByOne(url, imgPaths, successUp, failUp, count, length);
}
}
})
},
|
4，后台接口
@PostMapping("/uploadImg")
public String addSecondHandImg(String id, @RequestParam("file") MultipartFile[] files) {
//该接口被多次调用，这里写自己的业务，省略。。。
return "";
}
