如何使用Unity3D中的Microsoft Graph API上载/下载文件

microsoft-graph upload unity3d c#

LiefLayer · 技术社区 · 7 年前

我可以在Microsoft Graph上使用Unity3D进行OAuth 2登录,我为我的应用程序请求了此权限: https://graph.microsoft.com/files.readwrite.appfolder

在通常的代码流(重定向到URL、用户的权限、身份验证代码与令牌代码交换以及令牌与承载身份验证代码交换)之后,我就可以登录了。

问题是上载小文件不起作用: https://docs.microsoft.com/en-us/onedrive/developer/rest-api/api/driveitem_put_content

我认为这是我能做的最好的:

string myData = File.ReadAllText(Application.persistentDataPath + "/" + "provaupload.json");
    using (UnityWebRequest www = UnityWebRequest.Post("https://graph.microsoft.com/v1.0/me/drive/root:/AppTry/provaupload.json:/createUploadSession", myData)) {
        www.SetRequestHeader("Authorization", "Bearer <code>");
        www.SetRequestHeader("Content-Type", "application/json");
        yield return www.SendWebRequest();

        if (www.isNetworkError || www.isHttpError) {
            Debug.Log(www.error + " " + www.downloadHandler.text);
        } else {
            Debug.Log("Upload complete! " + www.downloadHandler.text);
        }
    }

我得到这个错误:

Generic/unknown HTTP error {
  "error": {
  "code": "BadRequest",
  "message": "Unable to read JSON request payload. Please ensure Content-Type header is set and payload is of valid JSON format.",
  "innerError": {
    "request-id": "id",
    "date": "2018-07-20T06:24:30"
  }
}

我还尝试了www类,或者用put代替post,但是我得到了“无效的api”。可能我的问题出在基本URL中: https://graph.microsoft.com/v1.0/me

或者可能在路上根目录:/apptry/provaupload.json

或者在许可证里。

我真的不知道。

如果您知道如何使用Microsoft Graph和一个驱动器进行REST调用(即使不在Unity3D中,甚至不知道如何解决我的特定问题),那么最好举个例子。

UploadHandler UTF8 PUT POST

string myData = File.ReadAllText(Application.persistentDataPath + "/" + "provaupload.json");
string url = "https://graph.microsoft.com/v1.0/me/drive/root:/AppTry/provaupload.json:/content";

using (UnityWebRequest www = new UnityWebRequest(url, "PUT"))
{
    byte[] dataToSend = new System.Text.UTF8Encoding().GetBytes(myData);
    www.uploadHandler = (UploadHandler)new UploadHandlerRaw(dataToSend);
    www.downloadHandler = (DownloadHandler)new DownloadHandlerBuffer();

    www.SetRequestHeader("Authorization", "Bearer <code>");
    www.SetRequestHeader("Content-Type", "application/json");
    yield return www.SendWebRequest();

    if (www.isNetworkError || www.isHttpError)
    {
        Debug.Log(www.error + " " + www.downloadHandler.text);
    }
    else
    {
        Debug.Log("Upload complete! " + www.downloadHandler.text);
    }
}
