注意 scope 权限 , redirect_uri 授权成功跳转地址, 获取code, 所有的 auth3 都是这个流程

public String getAuthUrl(Map params0){
String url = Constants.get("login_url") +"/authorize";
url += "?client_id=" + Constants.get("client_id");
url += "&response_type=code";
url += "&redirect_uri=" + Constants.get("redirect_uri");
url += "&scope=offline_access%20Files.ReadWrite.All%20Sites.Read.All%20User.Read";
return url;
}
code是上面获取到的, 注意 redirect_uri 相同 , client_secret 密钥, 在建立clientid的地方
获取到 access_token- 用于api请求的token, expires_in - token过期时间缓存一下, refresh_token-刷新token 用的
public String getToken(Map params0){
String code = params0.get("code");
String url = Constants.get("login_url") +"/token";
HashMap params = new HashMap<>();
params.put("client_id", Constants.get("client_id"));
params.put("redirect_uri", Constants.get("redirect_uri"));
params.put("client_secret", Constants.get("client_secret"));
params.put("code", code);
params.put("grant_type", "authorization_code");
Map resp = OKHttpUtil.post(url, params);;
LogUtil.info("getToken->" + resp);
String token = (String) resp.get("access_token");
int expires_in = (int) resp.get("expires_in") ;
VcodeUtil.timedCache.put("access_token", token, expires_in* 1000);
String refresh_token = (String) resp.get("refresh_token");
VcodeUtil.timedCache.put("refresh_token", refresh_token, expires_in* 1000 * 36);
return token;
} 缓存 access_token 3600秒, 失效后使用 refresh_token 刷新 access_token , refresh_token的 时效较长, 微软没有指定具体多久,
测试 至少在 天级别以上
public String getTokenByCache(Map params0){
String token = (String) VcodeUtil.timedCache.getNotUpLastAccess("access_token");
if (token != null) {
return token;
}
String refresh_token = (String) VcodeUtil.timedCache.getNotUpLastAccess("refresh_token");
String url = Constants.get("login_url") +"/token";
HashMap params = new HashMap<>();
params.put("client_id", Constants.get("client_id"));
params.put("scope", "offline_access Files.ReadWrite.All Sites.Read.All User.Read");
params.put("refresh_token", refresh_token);
params.put("redirect_uri", Constants.get("redirect_uri"));
params.put("client_secret", Constants.get("client_secret"));
params.put("grant_type", "refresh_token");
Map resp = OKHttpUtil.post(url, params);;
LogUtil.info("getToken->" + resp);
token = (String) resp.get("access_token");
int expires_in = (int) resp.get("expires_in") ;
VcodeUtil.timedCache.put("access_token", token, expires_in* 1000);
refresh_token = (String) resp.get("refresh_token");
VcodeUtil.timedCache.put("refresh_token", refresh_token, expires_in* 1000 * 36);
return token;
} //PUT /me/drive/items/{parent-id}:/{filename}:/content , 上传地址很费解, 这里我做了例子
这样好理解一点, 使用 绝对路径上传, body 直接是文件流
/SEARCH_APP/upload/201912/10/Q5pe5A.jpg 这里是文件路劲
https://graph.microsoft.com/v1.0/me/drive/root:/SEARCH_APP/upload/201912/10/Q5pe5A.jpg:/content
上传成功后 会返回 这个 item 的信息, 里面有下载地址, 保存这个 id, 和 路径, 下载的时候提供 itemid 下载方式 和路径方式
public String upload(String uploadPath, String suffix, ByteArrayOutputStream out) throws Exception{
byte[] bytes = out.toByteArray();
long id = MD5.md5_long(bytes);
Map ins = getIns(id);
if(!ins.isEmpty()) {
return (String) ins.get("itemid");
}
String date = BaseUtil.getFormatDate().replaceFirst("/", "");
uploadPath += date;
String filename = uploadPath + "/" + RandomStringUtils.randomAlphanumeric(6) +"." + suffix;
//PUT /me/drive/items/{parent-id}:/{filename}:/content
String url = "https://graph.microsoft.com/v1.0/me/drive/root:" + filename +":/content";
HttpRequest request = new HttpRequest(url, Method.put);
request.setContentType("image/jpeg");
request.addHeader("Authorization", "Bearer " + getTokenByCache(null));
request.setRequestBody(bytes);
HttpResponse res = OKHttpUtil.request(request);
// 返回的 id 就是 itemid, 可以用此id做一些操作 保存itemid 和 filePath
String resStr= res.getResponseString();
Map resMap = (Map) OKHttpUtil.deserialize(resStr);
String itemid = (String) resMap.get("id");
return itemid;
} String url = "https://graph.microsoft.com/v1.0/me/drive/items/"+itemid+"/content"; // 下載 按itemid
String url = "https://graph.microsoft.com/v1.0/me/drive/root:" + filepath +":/content"; // 按文件路劲
看代码, 上面 带了注释, 下载地址, 预览地址, 和分享地址, 具体实现 看 oneApi, 我都测试过
成功请求后会出现 302 跳转, 一般 httpclient 都会自己跳, 不想跳的找配置 获取Location 可以查看地址
public Object downLoad(Map params) throws Exception{
String itemid = params.get("id");
// String url = "https://graph.microsoft.com/v1.0/me/drive/root:" + filepath +":/content"; // 按文件路劲
// String url = "https://graph.microsoft.com/v1.0/me/drive/items/01RHKEMNKSNBGOHRSDPBHJI43LRLM62MV7/preview"; // 預覽按itemid
// String url = "https://graph.microsoft.com/v1.0/me/drive/items/01RHKEMNKSNBGOHRSDPBHJI43LRLM62MV7/createLink"; // 分享按itemid
String url = "https://graph.microsoft.com/v1.0/me/drive/items/"+itemid+"/content"; // 下載 按itemid
HttpRequest request = new HttpRequest(url, Method.get);
request.addHeader("Authorization", "Bearer " + getTokenByCache(null));
//request.setContentType("application/json");
//request.setRequestBody("{\"chromeless\":\"true\"}".getBytes());
HttpResponse resp = OKHttpUtil.request(request);
// System.out.println(resp.getResponseString());
// System.out.println(resp.getHeader("Location")); // 302 跳转, 自动重新获取图片 URL
return resp.getRespInputsStream();
