php上传图片到个人百度网盘

平时使用百度网盘，都是下载网盘客户端来上传和下载文件。如果想要在系统中使用百度网盘的上传和下载，肯定要用程序来操作客户端。
好在，百度网盘开放平台提供了各种实用的接口，在我们开发的程序中，只需要调用接口，就能够完成文件的上传和下载功能。
在百度网盘开发平台中提供的各种接口文档虽然比较详细，但是没有demo，有些问题上还是容易卡住，本文结合百度网盘开放平台的接口和其他的百度接口来实现网盘文件的操作，包括授权登录，文件列表，文件信息，上传（分片）文件，下载文件，删除文件，创建文件夹
1.登录百度网盘开放平台，网址：https://pan.baidu.com/union/home，点击右上角的控制台，进入后点击创建应用
2.创建应用后记下应用密钥，密钥，签名密钥，别忘了填写oauth授权页面地址
3.jquery获取上传文件，判断文件大小小于2G直接上传，大于2G分片上传
var chunkSize = 1024 * 1024 * 1024 * 2; // 单个分片大小
var chunkList = []; // 分片数据列表
var file = null; // 上传文件
var activeChunk = 0; // 已完成的分片数量
var chunkSum = 0; //分片数量
var filesize = 0; //文件大小
var filename = ''; //文件名称
var sku = 'doc_name'; //上传文件夹名称
var cl = ''; //上传点击按钮
var tplj = '';
$(document).on("change",cl,function(e) {
files = e.target.files;
if(files['length'] == 1){
file = e.target.files[0];
filesize = file.size;
filename = file.name;
setChunkFile(file);
if (!chunkList) return;
activeChunk = 0;
chunkSum = chunkList.length;
for(var i = 0; i < chunkSum; i++) {
uploadChunk(chunkList[i], i, chunkSum,0);//上传分片
}
}
if(files['length'] > 1){
for(var n=0;n<files['length'];n++){
file = e.target.files[n];
filesize = file.size;
filename = file.name;
setChunkFile(file);
if (!chunkList) return;
activeChunk = 0;
chunkSum = chunkList.length;
for(var i = 0; i < chunkSum; i++) {
uploadChunk(chunkList[i], i, chunkSum,n);//上传分片
}
}
}
});
/**

*/
function setChunkFile(file) {
chunkList = [];
var s = e = 0;
var chunkNum = Math.ceil(filesize/chunkSize);
while(true) {
if (e >= filesize) {
e = filesize;
break;
}
e = s + chunkSize;
var slices = file.slice(s, e);
chunkList.push(slices);
s = e;
}
}
