我正在尝试使用httpClient库上传图像（多部分/表单数据）。我可以使用httpPost方法和byteArrayRequest estEntity上传图像。以下是我使用的代码：
File file = new File(imageFilePath);
HttpClient client = new HttpClient();
PostMethod method = new PostMethod("https://domain/link/folderId/files?access_token="+accessToken);
method.addRequestHeader("Content-Type","multipart/form-data;boundary=AaB03x");
String boundary = "AaB03x";
StringBuilder builder = new StringBuilder();
builder.append("--");
builder.append(boundary+"\r\n");
builder.append("Content-Disposition: form-data; name=\"file\"; filename=\"photo.jpg\"");
builder.append("\r\n");
builder.append("Content-Type: image/jpeg");
builder.append("\r\n");
builder.append("\r\n");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
baos.write(builder.toString().getBytes("utf-8"));
builder.setLength(0);
InputStream is = new FileInputStream(file);
byte[] buffer = new byte[4096];
int nbRead = is.read(buffer);
while(nbRead > 0) {
baos.write(buffer, 0, nbRead);
nbRead = is.read(buffer);
}
is.close();
builder.append("\r\n");
builder.append("--");
builder.append(boundary);
builder.append("--");
builder.append("\r\n");
baos.write(builder.toString().getBytes("utf-8"));
method.setRequestEntity(new ByteArrayRequestEntity(baos.toByteArray(), "multipart/form-data; boundary=\"" + boundary + "\""));
System.out.println(method.getRequestEntity().toString());
client.executeMethod(method);
但是我正在处理的项目要求我使用httpRequest而不是Http Postmethod。我尝试了basicHttpEntityEnClosingRequest，但是相同的setEntity方法只接受httpEntity（我使用的是ByteArrayRequest estEntity）。
有人能帮助我如何修改代码，使其使用HttpRequest（或其子类型）而不是Postmethod吗？
-我使用apache-mime库将带有消息的图像发布到Web服务器。
以下是我正式生产环境的代码：
public String postDataCreation(final String url, final String xmlQuery,final String path){
final StringBuilder sa = new StringBuilder();
final File file1 = new File(path);
Thread t2 = new Thread(new Runnable(){
public void run() {
try
{
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(url);
FileBody bin1 = new FileBody(file1);
MultipartEntity reqEntity = new MultipartEntity();
reqEntity.addPart("dish_photo", bin1);
reqEntity.addPart("xml", new StringBody(xmlQuery));
post.setEntity(reqEntity);
HttpResponse response = client.execute(post);
HttpEntity entity = response.getEntity();
InputStream i = entity.getContent();
Log.d("Vivek", i.toString());
InputStreamReader isr = new InputStreamReader(i);
BufferedReader br = new BufferedReader(isr);
String s = null;
while ((s = br.readLine()) != null) {
Log.d("YumZing", s);
sa.append(s);
}
Log.d("Check Now",sa+"");
}
catch (Exception ex){
Log.e("Debug", "error: " + ex.getMessage(), ex);
}
}
});
t2.start();
try {
t2.join();
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("Getting from Post Data Method "+sa.toString());
return sa.toString();
}
