使用BigQuery命令行工具時出現OAuth 2.0不一致錯誤

Question

我正在使用BigQuery的命令行工具將數據加載到BigQuery中。

private void RunShellCmd(string cmd, string args) 
    { 
     ProcessStartInfo start = new ProcessStartInfo 
     { 
      FileName = cmd, 
      Arguments = args, 
      UseShellExecute = false, 
      RedirectStandardOutput = true 
     }; 

     using (Process process = Process.Start(start)) 
     { 
      using (StreamReader reader = process.StandardOutput) 
      { 
       string result = reader.ReadToEnd(); 

       if (OnMessage != null) 
       { 
        OnMessage(result);       
       } 
      } 
     } 
    } 

凡CMD是對BQ腳本工具和路徑ARGS是：

我用下面的方法運行通過C＃程序BQ工具 負荷--nosync --credential_file = _CRED_PATH_ --source_format = NEWLINE_DELIMITED_JSON --project_id = _PROJECT_ID_ _TABLE_URI_ _DATA_FILE_

從shell執行精確的命令時，它可以很好地工作。 然而，通過C＃程序中，我發現了以下的輸出：

Welcome to BigQuery! This script will walk you through the process of initializing your .bigqueryrc configuration file. 

First, we need to set up your credentials if they do not already exist.

Unexpected exception in init operation: EOF when reading a line

奇怪的是，該命令的實際工作，並正確地加載數據（也被最終輸出線證明）。 但由於某種原因，它前面有一個OAUTH 2.0錯誤。

有沒有人遇到過這樣的事情？ 任何想法可能會導致它？

謝謝！

爲什麼從c＃中調用bq.py工具而不是使用C＃客戶端？

C＃的客戶端可以在這裏找到： https://developers.google.com/api-client-library/dotnet/apis/#BigQuery_API 和ndocs在這裏： https://developers.google.com/resources/api-libraries/documentation/bigquery/v2/csharp/latest/annotated.html

如果你不想/不能使用C＃的客戶端，我的猜測，正在發生的事情是bq在寫出憑證文件（或讀取憑證文件）時遇到麻煩。可能這是由於Windows路徑問題（'/'vs'\'）或可能它嘗試寫入或讀取的路徑無法訪問。 （或者可能它寫入的路徑與下次嘗試讀取的路徑不匹配）。
