使用C#Xamarin Android将图像上传到Web

[英]Upload image to Web using C# Xamarin Android

  1. I want to upload my image using POST, but it always show an error while uploading the file ("There was an error uploading the file, please try again"). 我想使用POST上传图像,但是在上传文件时总是显示错误(“上传文件时出错,请重试”)。 When I echo $link , only "uploaded//" appears. 当我回显$link ,仅显示“ uploaded //”。

  2. How do I rename the "file" variable in $_FILES["file"] in my C# code? 如何在C#代码中的$_FILES["file"]中重命名“ file”变量?

variabel uriFotoAndr.Path return : variabel uriFotoAndr.Path返回:

/storage/sdcard1/DCIM/Camera/MYIMAGE.jpg /storage/sdcard1/DCIM/Camera/MYIMAGE.jpg

C# Code : C#代码:

System.Net.WebClient Client = new System.Net.WebClient();
Client.Headers.Add("Content-Type", "binary/octet-stream");

byte[] result = Client.UploadFile("my.web.com/ppl/post_image.php", "POST", uriFotoAndr.Path);
string s = System.Text.Encoding.UTF8.GetString(result, 0, result.Length);
Toast.MakeText(this, s, ToastLength.Long).Show();

PHP Code : PHP代码:

<?php
$uploads_dir = 'uploaded/'; 
if ($_FILES["file"]["error"] == UPLOAD_ERR_OK) 
 {
     $tmp_name = $_FILES["file"]["tmp_name"];
     $name = $_FILES["file"]["name"];
     $link= $uploads_dir."/".$name;
     if( move_uploaded_file($tmp_name, $link))
     {
        echo "Success: Picture Upload Successfully!";
     }
     else
     {
        echo "There was an error uploading the file, please try again!".$link;
     }
  }
  else
  {
     echo "Error: Picture not Uploaded";
  }
?>
