我正在使用REST服務來處理圖像,例如更改亮度或對比度。我目前有一個Windows窗體應用程序,我將圖像上傳到其他應用程序。將圖像作爲字節數組發送到REST服務
這裏是我的代碼到目前爲止休市接收字節:
IRestServiceImpl.cs
[OperationContract]
[WebInvoke(Method = "POST",
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.Wrapped,
UriTemplate = "json/{id}")]
string jsonData(byte[] id);
RestServiceImpl.svc.cs
public string jsonData(byte[] id) {
return "The byte array is" + id;
}
這是我從表單發送它的嘗試,但它只是在Visual Studio的控制檯中返回空白即
private async void btnRestSend_Click(object sender, EventArgs e) {
byte[] byteArray = ImageManipulation.ImgToByte(pictureBox1.Image);
ByteArrayContent byteContent = new ByteArrayContent(byteArray);
var url = "http://localhost:52278/RestServiceImpl.svc/json/";
HttpClient client = new HttpClient();
HttpResponseMessage response = await client.PostAsync(new Uri(url), byteContent);
string responseBody = await response.Content.ReadAsStringAsync();
Console.WriteLine(responseBody);
}
ImgToByte
public static byte[] ImgToByte(Image img) {
//Converts an Image to a Byte
ImageConverter converter = new ImageConverter();
return (byte[])converter.ConvertTo(img, typeof(byte[]));
}
我如何將字節數組被成功發送到其他服務,所以我可以在那裏操縱呢?
感謝提前:)
