我正在使用以下代码向PHP Web服务发送图像和文本。
try {
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpPost httpPost = new HttpPost(URL);
MultipartEntity entity = new MultipartEntity(
HttpMultipartMode.BROWSER_COMPATIBLE);
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.JPEG, 75, bos);
byte[] data = bos.toByteArray();
entity.addPart("files[]",
new ByteArrayBody(data, "myImage.jpg"));
entity.addPart("message0", new StringBody(caption.getText()
.toString()));
httpPost.setEntity(entity);
HttpResponse response = httpClient.execute(httpPost,
localContext);
BufferedReader reader = new BufferedReader(
new InputStreamReader(
response.getEntity().getContent(), "UTF-8"));
String sResponse = reader.readLine();
return sResponse;
} catch (Exception e) {
if (dialog.isShowing())
dialog.dismiss();
Toast.makeText(ImageUpload.this, e.getMessage(),
Toast.LENGTH_LONG).show();
Log.e(e.getClass().getName(), e.getMessage(), e);
return null;
}
}
它完美地工作。但这只是适用于一个图像，我想发送5个图像。
例如：Image1 - Text1
Image2 - Text2 等等。
所以我现在很困惑如何逐个存储5张图片，然后在点击按钮时将这些与其相关联的图像和文本一起发送到服务器。
我正在从手机相机获取图像。
