尝试使用 Google API Client libraries for Go 将数据上传到 BigQuery 时，我收到以下响应.

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "badRequest",
    "message": "Invalid Upload Request"
   }
  ],
  "code": 400,
  "message": "Invalid Upload Request"
 }
}

我的职位描述如下:

j := &bigquery.Job{
    Configuration: &bigquery.JobConfiguration{
        Load: &bigquery.JobConfigurationLoad{
            DestinationTable: &bigquery.TableReference{
                projectId,
                "xyz",
                name + "_" + yyyymmdd,
            },
            SkipLeadingRows: 1,
            FieldDelimiter:  "|",
            MaxBadRecords:   3,
            Schema: &bigquery.TableSchema{
                []*bigquery.TableFieldSchema{
                    {Name: "f1", Type: "STRING"},
                    {Name: "f2", Type: "STRING"},
                    {Name: "f3", Type: "STRING"},
                    {Name: "f4", Type: "STRING"},
                    {Name: "f5", Type: "STRING"},
                    {Name: "f6", Type: "STRING"},
                    {Name: "f7", Type: "STRING"},
                    {Name: "f8", Type: "STRING"},
                    {Name: "f9", Type: "STRING"},
                    {Name: "f10", Type: "STRING"},
                    {Name: "f11", Type: "STRING"},
                    {Name: "f12", Type: "STRING"},
                    {Name: "f13", Type: "STRING"},
                    {Name: "f14", Type: "STRING"},
                    {Name: "f15", Type: "STRING"},
                    {Name: "f16", Type: "STRING"},
                    {Name: "f17", Type: "STRING"},
                },
            },
        },
    },
}

FWIW，使用这个库的其他调用工作正常，所以我已经排除了 oauth 问题等。

编辑:我在请求发出前捕获了它。请注意，这是在 http.Client 能够添加 oauth header 之前。实际请求很大，所以我缩短了它并删除了标识符。

最佳答案

事实证明，这是由库中的一个错误引起的，该错误没有发送所需的“uploadType”查询参数。参见 these diffs用于修复错误的补丁。

然而，这暴露了我目前正在与作者一起修复的库中的另一个错误。修复完成后，我将更新此答案。

编辑:截至this patch ，上面提到的错误已修复。
