Android的多上傳與圖像列表

Question

有一個圖像列表，我想上傳到服務器

我使用httpmime，這裏是代碼：

for(File file : gs.id_img) { 
      builder.addPart("id_img[]", new FileBody(file)); 
     } 

但在後端似乎無法獲得發佈的價值，如何解決它？感謝

你有這樣

public void connectForMultipart() throws Exception { 
    con = (HttpURLConnection) (new URL(url)).openConnection(); 
    con.setRequestMethod("POST"); 
    con.setDoInput(true); 
    con.setDoOutput(true); 
    con.setRequestProperty("Connection", "Keep-Alive"); 
    con.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary); 
    con.connect(); 
    os = con.getOutputStream(); 
} 

public void addFormPart(String paramName, String value) throws Exception { 
    writeParamData(paramName, value); 
} 

public void addFilePart(String paramName, String fileName, byte[] data) throws Exception { 
    os.write((delimiter + boundary + "\r\n").getBytes()); 
    os.write(("Content-Disposition: form-data; name=\"" + paramName + "\"; filename=\"" + fileName + "\"\r\n" ).getBytes()); 
    os.write(("Content-Type: application/octet-stream\r\n" ).getBytes()); 
    os.write(("Content-Transfer-Encoding: binary\r\n" ).getBytes()); 
    os.write("\r\n".getBytes()); 

    os.write(data); 

    os.write("\r\n".getBytes()); 
} 
public void finishMultipart() throws Exception { 
    os.write((delimiter + boundary + delimiter + "\r\n").getBytes()); 
} 

工作，我已經改變了Content-Type: application/octet-stream\r\n"到Content-Type: image/jpeg\r\n\r\n和它的工作:)
