.NET 7 WPF应用调用Microsoft Graph上传OneDrive时出现ODataError

可能的问题及修复步骤 #

1. 租户ID拼写错误 #

你的代码中tenantId变量值包含空格（"Tena ntId"），这会导致认证请求的Authority地址无效，获取的令牌可能无法正确访问OneDrive。修复：替换为无空格的正确租户ID。

2. 自定义认证提供者冗余且存在兼容性风险 #

自定义CustomAuthenticationProvider手动处理请求头，不符合Microsoft Graph SDK v5+的官方推荐方式，容易出现权限传递错误。

修复：
移除自定义CustomAuthenticationProvider类，使用Azure.Core.AccessTokenCredential初始化GraphServiceClient，代码更简洁且可靠：

// 替换原有的graphClient初始化代码
var credential = new AccessTokenCredential(result.AccessToken);
graphClient = new GraphServiceClient(credential);

需要添加命名空间：using Azure.Core;

3. 冗余的Drive请求 #

你先调用graphClient.Me.Drive.GetAsync()获取Drive ID，再通过graphClient.Drives[myDrive.Id]访问，多了一次不必要的API请求。可以直接访问当前用户的Drive根目录。

修复：
将上传会话的请求代码简化为：

var uploadSession = await graphClient.Me.Drive.Root
    .ItemWithPath(Path.GetFileName(filePath))
    .CreateUploadSession
    .PostAsync(uploadSessionRequestBody);

4. 不完整的异常信息捕获 #

当前捕获ODataError时仅打印基础消息，无法获取错误代码和详细信息，难以定位具体问题（如权限不足、路径非法等）。

修复：
完善异常处理逻辑，打印完整错误信息：

catch (ODataError ex)
{
    var errorDetails = ex.Error.Details != null 
        ? string.Join("\n", ex.Error.Details.Select(d => $"{d.Code}: {d.Message}")) 
        : "无详细信息";
    MessageBox.Show($"上传失败:\n错误代码: {ex.Error.Code}\n消息: {ex.Error.Message}\n详细信息: {errorDetails}", 
        "错误", MessageBoxButton.OK, MessageBoxImage.Error);
}

额外检查项 #

• 确保Azure AD应用注册中已添加Files.ReadWrite.All权限，并已授予管理员同意（如果是租户范围内的应用）。
• 确认本地文件路径无特殊字符，OneDrive文件名符合命名规范。
