前言：?由于項目api是一臺服務器，upload也是一臺服務器，所以整體思路就是

1，先將zip上傳到upload服務器

2，在upload服務器上解壓zip。

3，在upload服務器上處理解壓的文件（基本上都是json?string）

4，通過接口調用將json?string傳入到接口中，進行數據庫的操作

一、html

<input id="discoverImg" type="file" name="" class="layui-input">
<input type='button' class="layui-btn layui-btn-primary" οnclick="getImg()" value='生成圖片'></input>

二、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);//將data轉化成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) {
}
});
}
}

三、Java、

?//一下代碼主要是組裝訪問upload的request和解析結果

public static Map getUploadZipPath(String domain,MultipartFile multipartFile){
String newUrl=null;
Map mapImags = new HashMap();
try {
// 換行符
final String newLine = "\r\n";
final String boundaryPrefix = "--";
// 定義數據分隔線
String BOUNDARY = "========7d4a6d158c9";
// 服務器的域名
URL url = new URL(domain+"/upload/UploadZipServlet");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
// 設置為POST情
conn.setRequestMethod("POST");
// 發送POST請求必須設置如下兩行
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setUseCaches(false);
// 設置請求頭參數
conn.setRequestProperty("connection", "Keep-Alive");
conn.setRequestProperty("Charsert", "UTF-8");
conn.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + BOUNDARY);
OutputStream out = new DataOutputStream(conn.getOutputStream());
// 上傳文件
String fileRealName = multipartFile.getOriginalFilename();//獲得原始文件名;
StringBuilder sb = new StringBuilder();
sb.append(boundaryPrefix);
sb.append(BOUNDARY);
sb.append(newLine);
// 文件參數,photo參數名可以隨意修改
sb.append("Content-Disposition: form-data;name=\"file\";filename=\"" + fileRealName + "\"" + newLine);
sb.append("Content-Type:application/octet-stream");
// 參數頭設置完以后需要兩個換行，然后才是參數內容
sb.append(newLine);
sb.append(newLine);
// 將參數頭的數據寫入到輸出流中
out.write(sb.toString().getBytes());
// 數據輸入流,用于讀取文件數據
DataInputStream in = new DataInputStream(multipartFile.getInputStream());
byte[] bufferOut = new byte[1024];
int bytes = 0;
// 每次讀1KB數據,并且將文件數據寫入到輸出流中
while ((bytes = in.read(bufferOut)) != -1) {
out.write(bufferOut, 0, bytes);
}
// 最后添加換行
out.write(newLine.getBytes());
in.close();
// 定義最后數據分隔線，即--加上BOUNDARY再加上--。
byte[] end_data = (newLine + boundaryPrefix + BOUNDARY + boundaryPrefix + newLine).getBytes();
// 寫上結尾標識
out.write(end_data);
out.flush();
out.close();
// 定義BufferedReader輸入流來讀取URL的響應
BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
JSONObject resultObj = JSON.parseObject(reader.readLine());
JSONObject resultData= resultObj.getJSONObject("data");
if(null == resultData)
throw new ServiceException("源文件不存在");
JSONArray imagesData = resultData.getJSONArray("images");
JSONArray imagesDataOthers = resultData.getJSONArray("zip");
List zipImags = Lists.newArrayList();
List zip = Lists.newArrayList();
if (imagesData.size() > 0){
for(int i = 0; i< imagesData.size(); i++){
JSONObject imageData = imagesData.getJSONObject(i);
String newUrlO = imageData.getString("oUrl");
String newUrlT = imageData.getString("tUrl");
System.out.println(" upload new Url =====>"+newUrlO);
System.out.println(" upload new Url =====>"+newUrlT);
newUrl = newUrlO + "," + newUrlT;
zipImags.add(newUrl);
}
mapImags.put("imags",zipImags);
}
if(imagesDataOthers.size()>0){
JSONObject imageDataOthers = imagesDataOthers.getJSONObject(0);
String newUrlOthers = imageDataOthers.getString("oUrl");
zip.add(newUrlOthers);
mapImags.put("zip",zip);
}

} catch (Exception e) {
System.out.println("發送POST請求出現異常！" + e);
e.printStackTrace();
}
return mapImags;
}

}

還有一個類，就是進行數據庫的處理的接口
首先將json string轉化成json object，之后自己就可以解析啦。。。 JSONObject json = JSONObject.parseObject(zipPath);
Map map = (Map)json;
