解决方案

从code和错误我想你忘了加<一个href=\"http://www.findjar.com/jar/org/apache/httpcomponents/httpmime/4.0/httpmime-4.0.jar.html?all=true\"相对=nofollow>在构建路径httpmime-4.0.jar 文件。

示例code：

  HttpPost httpost =新HttpPost（URL上传文件）;MultipartEntity实体=新MultipartEntity（）;
entity.addPart（myIdentifier，新StringBody（someValue中））;
entity.addPart（myAudioFile，新FileBody（文件））;httpost.setEntity（实体）;
HTT presponse响应;
响应= httpclient.execute（httpost）;
 

看我在这太问题的答案。

解决方案

From your code and error I think you forgot to add httpmime-4.0.jar file in your build path.

Example Code:

HttpPost httpost = new HttpPost("url for upload file");

MultipartEntity entity = new MultipartEntity();
entity.addPart("myIdentifier", new StringBody("somevalue"));
entity.addPart("myAudioFile", new FileBody(File));

httpost.setEntity(entity);
HttpResponse response;
response = httpclient.execute(httpost);
