Question

我有一个Android应用程序将文件上传到服务器，它在本地主机上没有任何问题，但在服务器上没有工作，我检查了路径并且它正确，

日志cat错误：未找到：404

如果我将网址粘贴到浏览器中，则将其复制

我在同一个地址（up3.php）中有另一个php文件，那个工作没有任何问题，但在那个我使用Json发送文本，而不是上传文件

我搜索了解决方案，但没有找到任何内容，

这是我的代码：

String upLoadServerUri = "http://live.mysite.com/up-file.php";

public int uploadFile(String sourceFileUri) {


    String fileName = sourceFileUri;

    HttpURLConnection conn = null;
    DataOutputStream dos = null;  
    String lineEnd = "\r\n";
    String twoHyphens = "--";
    String boundary = "*****";
    int bytesRead, bytesAvailable, bufferSize;
    byte[] buffer;
    int maxBufferSize = 1 * 1024 * 1024; 
    File sourceFile = new File(sourceFileUri); 

    if (!sourceFile.isFile()) {

           dialog.dismiss(); 

           runOnUiThread(new Runnable() {
               public void run() {
               }
           }); 

           return 0;

    }
    else
    {
           try { 

                 // open a URL connection to the Servlet
               FileInputStream fileInputStream = new FileInputStream(sourceFile);
               URL url = new URL(upLoadServerUri);

               // Open a HTTP  connection to  the URL
               conn = (HttpURLConnection) url.openConnection(); 
               conn.setDoInput(true); // Allow Inputs
               conn.setDoOutput(true); // Allow Outputs
               conn.setUseCaches(false); // Don't use a Cached Copy
               conn.setRequestMethod("POST");


               conn.setRequestProperty("Accept-Charset", "UTF-8");

Answer 1

http://live.mysite.com/up-file.php会抛出404错误，这就是它无效的原因

$ wget http://live.mysite.com/up-file.php

在浏览器中，它显示了一个花哨的404页面，但仍然是404

404错误 - 找不到文件您要查找的页面或文件不在此处。

Answer 2

我找到了解决方案，我不知道为什么但httprequest找不到子域名，而不是http://live.mysite.com/up.php它必须是http://www.live.mysite.com/up.php，如果有人知道为什么会发生这种情况告诉我plz

android上传文件到服务器得到404错误
