Answer 1

從您的代碼和錯誤，我認爲你忘了添加httpmime-4.0.jar文件在您的構建路徑。

示例代碼：

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); 

看我在這太問題的答案。

For uploading you should check with MIME Headers and buffer for file upload. 

You can try with code similar to given below :- 


DataOutputStream dos = new DataOutputStream(conn.getOutputStream()); 


String fName = uploadPath.substring(uploadPath 
            .lastIndexOf("/") + 1); 

          dos.writeBytes(LINE_START + BOUNDRY + LINE_END); 
          dos.writeBytes("Content-Disposition: form-data; name=\"uploaded\";" 
            + " filename=\"" + fName + "\"" + LINE_END); 
          dos.writeBytes("Content-Type: image/JPEG" + LINE_END); 
          dos.writeBytes(LINE_END); 

          // create a buffer of maximum size 
          bytesAvailable = fileInputStream.available(); 
          bufferSize = Math.min(bytesAvailable, maxBufferSize); 
          buffer = new byte[bufferSize]; 

          // read file and write it into form... 
          bytesRead = fileInputStream.read(buffer, 0, bufferSize); 
          totalBytes = 0; 

          while (bytesRead > 0) { 
           totalBytes += bytesRead; 
           dos.write(buffer, 0, bufferSize); 
           bytesAvailable = fileInputStream.available(); 
           bufferSize = Math.min(bytesAvailable, maxBufferSize); 
           bytesRead = fileInputStream.read(buffer, 0, bufferSize); 
          } 

          // send multipart form data necesssary after file data... 
          dos.writeBytes(LINE_END); 
          dos.writeBytes(LINE_START + BOUNDRY + LINE_START + LINE_END); 

          // close streams 
          fileInputStream.close(); 
          dos.flush(); 
          dos.close();

謝謝大家。我學到更多。 下面的鏈接對我來說最有用。

除了使用httpmime.jar，第二個辦法是複製源（*。JAVA）到yourproject/src文件夾......最後directiry結構應該像yourproject/SRC /組織/阿帕奇/ HTTP /實體/ mime/... 您不應該將jar庫和源文件混合到這些庫中... Everythihng對我來說工作得很好，所以請謹慎操作。

源代碼（*。java）你可以從http://hc.apache.org/downloads.cgi下載
選擇HttpClient 4.2.1：SOURCE - > 4.2.1.zip。

File file = new File("/sdcard/android.jpg"); 
try { 
    HttpClient client = new DefaultHttpClient(); 
    String postURL = "http://192.168.12.90/album/upload.php"; //web site 
    HttpPost post = new HttpPost(postURL); 
    FileBody bin = new FileBody(file);  
    MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE); 
    reqEntity.addPart("upf", bin); // first reference name(upf) should be the same as server side 
    post.setEntity(reqEntity); 
    HttpResponse response = client.execute(post); 
    HttpEntity resEntity = response.getEntity(); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
    } 

//server side php code 
$Destdir="upload"; 
$tmp_filename=$_FILES['upf']['tmp_name'];//post reference(upf).It must be the same as addPart("upf" 
$originalfilename=$_FILES['upf']['name'];//post reference(upf).It must be the same as addPart("upf" 
$server_filename= $Destdir. "/" .basename($originalfilename); 
move_uploaded_file($tmp_filename,$server_filename);
