如何在 C# 中使用 Quickbase API 上传文件？

Question

我正在使用 Quickbase C# SDK 从外部站点向 Quickbase 提交表单。我想随表格附上一个文件，但似乎不知道该怎么做。

下面是我的代码的精简版本：

ASPX

<form id="form1" runat="server">
<asp:TextBox ID="txtFileName" CssClass="textbox" Columns="40" runat="server"></asp:TextBox>
<input type="file" id="attachment1" runat="server" />
<asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClick="btnSubmit_Click" />
</form>

CS

protected void btnSubmit_Click(object sender, EventArgs e)
{
    IQClient client = QuickBase.Login("username", "password", "domain"); 
    IQApplication app = client.Connect("db_id", "app_token";
    AppInfo appInfo = app.GetApplicationInfo();
    IQTable table = app.GetTable("table_id");

    IQRecord newRecord = table.NewRecord();
    newRecord["File Name"] = txtFileName.Text;
    // attach file?
    newRecord.AcceptChanges();
    table.AcceptChanges();
    client.Logout();
}

提前致谢。

Answer 1

当然，在将问题提交到 StackOverflow 后我会弄清楚自己的问题。当然。

但是我会发布我的解决方案，以防其他人遇到同样的问题。

我必须向 QuickBase C# SDK 添加一个函数并重新编译 DLL 才能使其正常工作。

将此行添加到 IQRecord.cs：

void UploadFile(string columnName, string filePath);

将此函数添加到QRecord.cs中：

public void UploadFile(string columnName, string filePath)
{
    // create new field with columnName
    var index = GetColumnIndex(columnName);
    CreateNewField(index, columnName);

    // change field type to file
    Columns[index].ColumnType = FieldType.file;

    // Get field location with column index
    var fieldIndex = _fields.IndexOf(new QField(Columns[index].ColumnId));
    SetExistingField(index, fieldIndex, filePath);
}

像这样编译和使用：

// code to upload file to temporary location
newRecord.UploadFile("Story", "path_to_temporary_location");
// delete temporary file

public async Task<bool> UploadOrderTaxExemptQB()

{ bool isSuccess = false;

// Download file from the URL
using (HttpClient httpClient = new HttpClient())
{
    HttpResponseMessage response = await httpClient.GetAsync("hn-to-your-Payoneer-account-Payoneer-Login.png");
    if (response.IsSuccessStatusCode)
    {
        using (MemoryStream ms = new MemoryStream())
        {
            await response.Content.CopyToAsync(ms);
            ms.Position = 0;

            // Convert file to base64 string
            byte[] fileBytes = ms.ToArray();
            string base64File = Convert.ToBase64String(fileBytes);

            // Prepare the body with the file attachment
            var body = @"{
        ""to"":""fasdaer"",
        ""data"":[
            {
                ""8"":{""value"":" + 2231 + @"},
                ""7"":{""value"":{""filename"":""TaxExemptDocument.png"",""file"":""" + base64File + @"""}},
                ""6"":{""value"":""Tax Exempt Document""}
                    }
                ],
                ""fieldsToReturn"":[3,6]
            }";

            var qbResponse = await helper.QuickBasePostInsertRequestAsync(body);
            if (qbResponse.Content != null)
            {
                var typesResult = JsonConvert.DeserializeObject<QuickBaseDto>(qbResponse.Content);
                foreach (var item in typesResult.data)
                {
                    isSuccess = true;
                }
            }
        }
    }
}

return isSuccess;

}
