代码实例：https://ai.baidu.com/ai-doc/OCR/nk3h7xy2t
Dim fpsb_url As String = "https://aip.baidubce.com/rest/2.0/ocr/v1/vat_invoice?access_token={0}"
Dim data() As Byte = System.IO.File.ReadAllBytes("c:\\2.png") \'把文件字节流加载进来,
Dim d As String = Convert.ToBase64String(data)
Dim hc As New HttpClient(CExp(fpsb_url, AccessToken))
hc.Headers.Add("Content-Type", "application/x-www-form-urlencoded")
hc.C
Dim zjo As New JObject
Dim dt As String = """image=" & d & """"
hc.Content = dt \'提交数据并发起OA流程\'
zjo = JObject.Parse(hc.GetData()) \'获取流程发起ID
Output.Show(zjo.ToString)

感谢 有点蓝的指点，最终代码是个，可以正常返回数据；不能对d 进行转码
