我正在尝试将图像发送到 Imgur 的服务器。
一切都很顺利，我从解析器中获取了图像的 URL，但是当我尝试在网络浏览器上打开它时，我没有得到图像......只有一个“损坏的图像”图标。
我认为这是转换为字节数组的问题......但我不明白。请让我知道/修复我的代码。
Dim image As Image = image.FromFile(OpenFile.FileName)
Dim ms As New MemoryStream()
' Convert Image to byte[]
image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg)
Dim imageBytes As Byte() = ms.ToArray()
Dim wb As WebRequest = WebRequest.Create(New Uri("http://imgur.com/api/upload.xml"))
wb.ContentType = "application/x-www-form-urlencoded"
wb.Method = "POST"
wb.Timeout = 10000
Console.WriteLine(imageBytes.Length)
Dim parameters As String = "key=a801fa0b08a2117f5bb62b006f769b99&image=" + Convert.ToBase64String(imageBytes)
Dim encoding As New System.Text.UTF8Encoding()
Dim bytes As Byte() = encoding.GetBytes(parameters)
Dim os As System.IO.Stream = Nothing
Try
wb.ContentLength = bytes.Length
os = wb.GetRequestStream()
os.Write(bytes, 0, bytes.Length)
Dim xmlData As String = POSThandling.makePOSTrequest("http://imgur.com/api/upload.xml", New String() {parameters})
Dim xmlDoc As XmlDocument = New XmlDocument()
xmlDoc.LoadXml(xmlData)
Dim name As XmlNodeList = xmlDoc.GetElementsByTagName("original_image")
Dim imageText As String = (name(0).InnerText).ToString
messageText.Text = imageText.ToString
PanelUpload.Visible = False
UpImage.Enabled = True
SendMsg.Enabled = True
Finally
If Not (os Is Nothing) Then
End If
End Try
这是 C# 中的 Imgur API 示例

要回答您的问题，您需要首先将图像读入字节数组。然后将原始字节数组转换为Base64编码的字符串
FileStream fileStream = File.OpenRead(imageFilePath);
byte[] imageData = new byte[fileStream.Length];
fileStream.Read(imageData, 0, imageData.Length);
fileStream.Close();
string base64EncodedImage = System.Convert.ToBase64String(imageData);
