我正在使用xamarin.forms和System.Net.Http;
我正在使用帖子功能发送照片,这是:
public static async Task<String> PostImagemAsync(User user)
{
using (var client = new HttpClient())
{
try
{
var values = new List<KeyValuePair<string, string>>(0);
values.Add(new KeyValuePair<string, string>("email", user.usua_login));
values.Add(new KeyValuePair<string, string>("senha", user.usua_senha));
values.Add(new KeyValuePair<string, string>("foto", user.cont_imagem));
values.Add(new KeyValuePair<string, string>("json", "1"));
var content = new FormUrlEncodedContent(values);
HttpResponseMessage response = await client.PostAsync("http://ws.neosuite.com.br/login.asmx/foto", content);
var json = response.Content.ReadAsStringAsync().Result;
json = json.Substring(json.IndexOf('['));
json = json.Substring(0, json.LastIndexOf(']') + 1);
var userImage = JsonConvert.DeserializeObject<List<User>>(json);
return userImage[0].cont_imagem;
}
catch (Exception ex)
{
Debug.WriteLine(ex.Message);
return null;
}
}
}
我的图片(foto)是一个base64当我尝试发送它时,我会收到此错误:
URI无效:Uri字符串太长。
如何解决?

如果不将您的POST内容添加到网址中,请使用以下代码将其添加到正文
#version 420 core
layout (binding = 0) uniform sampler2D diffuse;
layout(location = 0) out vec4 color;
void main()
{
color = vec4(1, 1, 1, 1);
}
