【问题描述】:
我正在尝试将图片发送到网络服务器。当我在我的 Android 项目中调用一个方法时,我收到以下错误:找不到类 'org.apache.http.entity.mime.content.Filebody',从方法 com.example.tc.Send.send 引用。
即使我有以下导入,也会发生这种情况:
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.mime.MultipartEntity;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.impl.client.DefaultHttpClient;
这是方法所在的类的样子:
public class Send {
public Send(){
}
public static String send(String path) throws Exception {
String filePath = path;
String svar;
HttpClient httpclient = new DefaultHttpClient();
try {
HttpPost httppost = new HttpPost("path to web server");
FileBody pic = new FileBody(new File(filePath));
MultipartEntity requestEntity = new MultipartEntity();
requestEntity.addPart("file", pic);
httppost.setEntity(requestEntity);
System.out.println("executing request " + httppost.getRequestLine());
HttpResponse response = httpclient.execute(httppost);
HttpEntity responseEntity = response.getEntity();
System.out.println("----------------------------------------");
System.out.println(response.getStatusLine());
ByteArrayOutputStream outstream = new ByteArrayOutputStream();
response.getEntity().writeTo(outstream);
byte [] responseBody = outstream.toByteArray();
svar = new String(responseBody);
System.out.println(svar);
} finally {
try {
httpclient.getConnectionManager().shutdown();
}
catch (Exception ignore) {
}
}
return svar;
}
}
谁能看出问题出在哪里?
