android - Java.Net.ProtocolException：当我尝试将 laravel api 与 xamarin 一起使用时，流意外结束

Question

目前我想插入文本类型的数据和图像类型的文件，考虑的问题是图像，我不知道为什么。

代码 C#

public async Task<string> CreateUsuario(string nombre, string apellidos, String fechaNac, string sexo, string correo, string phone, string pass, MediaFile IdArchivo)
{
    string resultado = "";

    MultipartFormDataContent from = new MultipartFormDataContent();
    byte[] bytesI;
    if (IdArchivo != null)
    {
        using (var memoryStream = new MemoryStream())
        {
            IdArchivo.GetStream().CopyTo(memoryStream);
            bytesI = memoryStream.ToArray();
            HttpContent content = new StringContent("idArchivo");
            content.Headers.ContentLength=7000;
            from.Add(content, "idArchivo");
            content.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data")
            {
                Name = "idArchivo",
                FileName = String.Concat(Path.GetRandomFileName(), ".jpg")
            };
            from.Add(content);
        }
    }


    var contenido = new StringContent(nombre);
    from.Add(contenido, "Nombre");
    contenido = new StringContent(apellidos);
    from.Add(contenido, "Apellidos");
    contenido = new StringContent(fechaNac);
    from.Add(contenido, "FechaNac");
    contenido = new StringContent(sexo);
    from.Add(contenido, "Sexo");
    contenido = new StringContent(correo);
    from.Add(contenido, "Correo");
    contenido = new StringContent(phone);
    from.Add(contenido, "Phone");
    contenido = new StringContent(pass);
    from.Add(contenido, "Pass");


    HttpClient client = new HttpClient();

    try
    {

        var response = new HttpResponseMessage();
        response = await client.PostAsync(string.Concat(URL, "usuarios"), from);
        resultado = await response.Content.ReadAsStringAsync();
    }
    catch (Exception ex)
    {

    }

    return resultado;
}

在邮递员中，如果我使用邮递员方法正确插入并在请求中使用文件，但是当我想为 xamarin 进行插入时，不再发出请求。

我更改了具有 debian 9 操作系统的服务器的 php.ini，以将 upload_max_size 和 post_max_size 分别增加到 200 和 800 MB，以增加文件发送容量，但它无论如何都不起作用。

代码 AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="1" android:versionName="1.0" package="com.companyname.enyeradminapp">
    <uses-sdk android:minSdkVersion="21" android:targetSdkVersion="28" />
    <application android:label="EnyerAdminApp.Android" android:usesCleartextTraffic="true" android:theme="@style/MainTheme"></application>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.CAMERA"/>

    <application android:label="EnyerAdminApp.Android" android:usesCleartextTraffic="true">
        <provider android:name="android.suport.v4.content.FileProvider"
                  android:authorities="com.companyname.enyeradminapp.fileprovider"
                  android:exported="false"
                  android:grantUriPermissions="true">
            <meta-data android:name="android.support.FILE_PROVIDER_PATHS"
                       android:resource="@xml/file_paths"></meta-data>
        </provider>
    </application>
</manifest>

代码 AssemblyInfo.cs

 // Add some common permissions, these can be removed if not needed
    [assembly: UsesPermission(Android.Manifest.Permission.Internet)]
    [assembly: UsesPermission(Android.Manifest.Permission.WriteExternalStorage)]
    [assembly: Application(UsesCleartextTraffic = true)]

正如您在上面的代码中看到的，我在清单和 AssemblyInfo.cs 中添加了代码行 UsesCleartextTraffic = true

我得到的错误如下：
