我使用JSZIP库文件(
)以这种方式为2 xml文件创建了一个zip文件jszip.js
jszip-load.js
jszip-inflate.js
jszip-deflate.js
var zip = new JSZip();
zip.file("hi.xml", "<?xml version="1.0"?><root/></root></xml>");
zip.file("hello.xml", "<?xml version="1.0"?><pest/></pest></xml>");
//var content = zip.generate({ compression: "DEFLATE" });
var content=zip.generate({base64: true, binary: true, compression: "DEFLATE" });
这个压缩部分是成功的,因为我能够获得带有2个以上文件的downloads.zip hi.xml&amp;我的下载文件夹中的hello.xml,如果我添加此代码,
location.href="data:application/zip;base64,"+content;
但是我在通过ajax上传这个zip文件而不使用html格式时遇到了困难。这就是我在代码中所做的,
var oBlob = new (window.BlobBuilder || window.WebKitBlobBuilder ||
window.MozBlobBuilder || window.MSBlobBuilder)();
var raw = atob(content); //decode the base64 string
var rawLength = raw.length;
var uInt8Array = new Uint8Array(rawLength);
for (var i = 0; i < rawLength; ++i) { //convert to uInt8Array
uInt8Array[i] = raw.charCodeAt(i);
}
oBlob.append(uInt8Array.buffer); //append it to blobbuilder
oMyForm.append(content, oBlob.getBlob("application/zip")); //because you create a zip file, so get the zip type
//send it
$.ajax({
type: 'POST',
url: 'requestURL',//java spring servlet URL
async: false,
data: {
name:'user',
files:oMyForm
},
success: function(msg){
},
error : function(jqXHR, textStatus, errorThrown) {
if(typeof jqXHR == 'object'){
if(typeof jqXHR.responseText != 'undefined'){
if(jqXHR.responseText == 'success'){
}
}
}
}
});
有人可以在这个问题上帮助我吗?
我也是这样做的,
var oBlob = new (window.BlobBuilder || window.WebKitBlobBuilder ||
window.MozBlobBuilder || window.MSBlobBuilder)();
var raw = atob(content); //decode the base64 string
var rawLength = raw.length;
var uInt8Array = new Uint8Array(rawLength);
for (var i = 0; i < rawLength; ++i) { //convert to uInt8Array
uInt8Array[i] = raw.charCodeAt(i);
}
oBlob.append(uInt8Array.buffer); //append it to blobbuilder
oMyForm.append(content, oBlob.getBlob("application/zip")); //because you create a zip file, so get the zip type
//send it
var oReq = new XMLHttpRequest();
oReq.open("POST", 'requestURL');
oReq.send(oMyForm);
我在这里失踪的是什么?为什么zip文件没有发布到服务器?
有人可以帮助我吗?
答案 0 :(得分:1)
除此之外,请务必使用最新的JSZip版本(例如,jszip-inflate.js不再存在)。
灵感来自How can javascript upload a blob?:
var zip = new JSZip();
zip.file("hello.xml", "...");
var content = zip.generate({
type: "blob",
compression: "DEFLATE"
});
var fd = new FormData();
fd.append('name', 'user');
fd.append('zip', content);
$.ajax({
type: 'POST',
url: 'requestURL',
data: fd,
processData: false,
contentType: false
}).done(function(data) {
console.log(data);
});
