我正在尝试使用 HttpClient 和 MultipartEntity 将图像从 Adroid 应用程序上传到 php 网络服务器。
这是我的代码片段:
protected Void doInBackground(Void... params) {
HttpClient client = new DefaultHttpClient();
client.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
HttpPost post = new HttpPost( "http://URL/upload.php" );
try {
MultipartEntity entity = new MultipartEntity( );
entity.addPart("type", new StringBody("photo"));
entity.addPart("data", new FileBody(new File (this.path)));
post.setEntity(entity);
post.getParams().setBooleanParameter(CoreProtocolPNames.USE_EXPECT_CONTINUE, false);
post.addHeader( "Content-Type", "multipart/form-data; ");
HttpResponse response = client.execute(post);
HttpEntity resEntity = response.getEntity();
System.out.println(response.getStatusLine());
client.getConnectionManager().shutdown();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
在 php 文件中,我添加了 print_r($_FILE) 来查看数组的内容,它显示的是一个空数组。
执行 HttpClient 后 LogCat 显示以下内容
06-17 14:54:03.908: I/System.out(1256): HTTP/1.1 200 OK
06-17 14:54:03.998: D/111(1256): Array

谁能告诉我我必须添加到 Android 代码中吗?
