Preface: As the project is a server api, upload is also a server, so the whole idea is
1, first upload the zip to upload server
2, extract the zip on the upload server.
3, the file upload process decompression on the server (basically json string)
4, the interface call json string to pass through the interface, the operation of the database
One, html
<input id="discoverImg" type="file" name="" class="layui-input">
<input type='button' class="layui-btn layui-btn-primary" onclick="getImg()" value='生成图片'></input>
Two, JS
function getImg(){
var zipUpdate = $("#zipId")[0].files[0];
var formData = new FormData();
formData.append("zipFile",zipUpdate);
uploadZip(formData,callback);
}
function uploadZip(formData, callback){
$.ajax({
url : '/uploadZip',
method : 'POST',
async: false,
processData: false,
contentType:false,
data : formData,
success : function(result) {
callback(result)
}
})
}
function callback(result){
if(result.resultCode==1){
var emojiName = $(".emojiName").val();
// var emojiPath = $(".emojiPath").val();
var emojiProfile = $(".emojiProfile").val();
var emojiEveryName = $(".emojiEveryName").val();
var emojiPath = JSON.stringify(result.data);//将data转化成json String
Common.invoke({
path : '/add',
data : {
'zipName':emojiName,
'zipPath':emojiPath,//json String
'zipProfile': emojiProfile,
'nameStr' :emojiEveryName
},
successMsg : "",
errorMsg : "",
successCb : function(result) {
}
},
errorCb : function(result) {
}
});
}
}

first json string will be converted into json object, after that they can resolve the matter. . .
