[Android开发]Android 文件上传

  1. HttpClient模拟表单上传
    如果Android中自带的HttpClient不能实现上传的功能,就下载HttpClient 3.1版本

    public void upload(View view){
    HttpClient client = new HttpClient();
    PostMethod filePost = new PostMethod("http://192.168.1.100:8080/web/UploadServlet");;
    try {
    String path = et_path.getText().toString().trim();
    File file = new File(path);
    if(file.exists()&&file.length()>0){
    Part[] parts = {new StringPart("nameaaaa", "valueaaa"),
    new StringPart("namebbb", "valuebbb"),
    new FilePart("pic", new File(file.getAbsolutePath()))};
    filePost.setRequestEntity(new MultipartRequestEntity(parts, filePost.getParams()));
    client.getHttpConnectionManager().getParams()
    .setConnectionTimeout(5000);
    int status = client.executeMethod(filePost);
    if(status ==200){
    Toast.makeText(this, "上传成功", 1).show();
    }else{
    Toast.makeText(this, "上传失败", 1).show();
    }
    }
    else{
    Toast.makeText(this, "上传的文件不存在", 0).show();
    }
    } catch (Exception e) {
    e.printStackTrace();
    /**如果出现异常一定记得要释放*/
    filePost.releaseConnection();
    }
    }
    
  2. 模拟Http请求上传
