可以任何一个解释我如何能使POST请求到web上的URL与不同类型的数据，在我的情况下，我有一个图像和两个字符串类型的值发送到PHP服务器。
这是我已经做过的
var stream = await file.OpenStreamForReadAsync();
var streamcontent = new StreamContent(stream);
streamcontent.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data")
{
Name = "photo",
FileName = file.Name
};
streamcontent.Headers.ContentType = new MediaTypeHeaderValue("image/jpeg");
MultipartFormDataContent multipart = new MultipartFormDataContent();
multipart.Add(streamcontent);
try
{
descContent = mytextbox.Text;
var stringcontent = new StringContent(descContent);
stringcontent.Headers.ContentType.Parameters.Add(new NameValueHeaderValue("description", descContent));
multipart.Add(stringcontent);
HttpResponseMessage res = await client.PostAsync(new Uri("http://localhost/web/test/index.php"), multipart);
res.EnsureSuccessStatusCode();
mytextbox.Text = await res.Content.ReadAsStringAsync();
}
catch (HttpRequestException ex)
{
mytextbox.Text = ex.Message;
}
这个代码将发送图像文件，但不是描述(字符串)，我已经在互联网上搜索，但我找不到合适的答案。
下面是PHP代码
if (isset($_FILES['photo']))
{
echo $_FILES["photo"]["name"] . "<br>";
}
else
{
echo "Image: Error<br>";
}
if (isset($_POST['description']))
{
echo $_POST['description'];
}
else
{
echo "Text: Error";
}
感谢您的回复。
谢谢你
我找了很多，终于找到了出路。下面是代码
HttpClient client = new HttpClient();
client.BaseAddress = new Uri("http://www.yourdomain.com");
MultipartFormDataContent form = new MultipartFormDataContent();
HttpContent content = new StringContent("your string type data you want to post");
form.Add(content, "name");
var stream = await file.OpenStreamForReadAsync();
content = new StreamContent(stream);
content.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data")
{
Name = "image",
FileName = file.Name
};
form.Add(content);
var response = await client.PostAsync("index.php", form);
mytextblock.Text = response.Content.ReadAsStringAsync();
我把它写在我的博客上，下面是代码。：-）HappyCoding
