As shown in the picture above, after entering the content and adding pictures, click "Publish". Some devices do not respond. I have tried it on the test machine in hand and on my colleagues' mobile phones. The problem cannot be reproduced. Most of the mobile phones reported for failure are IOS6 and above. on WeChat

Backend colleagues reported that the frontend did not submit data (no logs were submitted), and the backend factors were temporarily excluded

Now we need to start with the front-end code to find the problem. How do I start testing the code?

Currently we have not added front-end exception monitoring

Approximate implementation ideas:

1. An object is defined to save the information of uploaded images

var uploads = {
    localId: [],
    serverId: []
};

2. When the user selects an image, call wx.chooseImage on the WeChat side, stuff the returned results (res.localIds) into (uploads.localId), cache them, and display the results on the page (Figure 1 above)

wx.chooseImage({
    count: 9,
    success: function (res) {
        for(var i=0; i<res.localIds.length; i++) {
            var _key = res.localIds[i];
            if(!selectedImageMap[_key]) {
                wx_uploads_localIds.push(_key);
                selectedImageMap[_key] = true; //防止圖片重復(fù)
            }
        }
        //頁(yè)面本地緩存，選擇班級(jí)會(huì)跳轉(zhuǎn)到另外一個(gè)頁(yè)面，需要將選擇的圖片信息緩存
        setPageSessionInfo();
        //修改標(biāo)題
        setTitle('動(dòng)態(tài)編輯');
        //再頁(yè)面上展示已選圖片
        _showSelectedPic();
        return false;
    }
});

3. Click "Publish", call wx.uploadImage to upload the image, stuff the returned serverId into (uploads.serverId) and cache it, and then submit uploads.serverIds in batches

//上傳處理
function _uploadProccess() {
    var _localId = uplods.localId.shift();
    wx.uploadImage({
        localId: _localId, // 需要上傳的圖片的本地ID，由chooseImage接口獲得
        isShowProgressTips: 1,// 默認(rèn)為1，顯示進(jìn)度提示
        success : function(res){
            var serverId = res.serverId; // 返回圖片的服務(wù)器端ID
            uplods.serverId.push(serverId);
            if(uplods.localId.length == 0) {
                //上傳隊(duì)列清空, 調(diào)用發(fā)送方法
            } else {
                _uploadProccess(); //成功繼續(xù)上傳且圖片為上傳完成
            }
        },
        fail : function(){
            //提示失敗
            return false;
        }
    });
}
