php用於從MultipartEntity接收圖像和文本

Question

我試圖通過MultipartEntity上傳圖像和一些文本。 我可以上傳和接收圖像，但是當我嘗試添加一個Stringbody時，我似乎無法接收它。 這裏是我的Android代碼

imports ETC... 

public void oncreate(){ 
..... 
nameValuePairs.add(new BasicNameValuePair("image", exsistingFileName)); 
nameValuePairs.add(new BasicNameValuePair("title", "title")); 
} 

public void post(String url, List<NameValuePair> nameValuePairs) { 
HttpClient httpClient = new DefaultHttpClient(); 
HttpContext localContext = new BasicHttpContext(); 
HttpPost httpPost = new HttpPost(url); 


try { 
    MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE); 

    for(int index=0; index < nameValuePairs.size(); index++) { 
     if(nameValuePairs.get(index).getName().equalsIgnoreCase("image")) { 
      System.out.println("post - if"); 
      // If the key equals to "image", we use FileBody to transfer the data 
      entity.addPart(nameValuePairs.get(index).getName(), new FileBody(new File (nameValuePairs.get(index).getValue()))); 

     } else { 
      System.out.println("post - else"); 
      // Normal string data 
      entity.addPart(nameValuePairs.get(index).getName(), new StringBody(nameValuePairs.get(index).getValue())); 
     } 
    } 
    System.out.println("post - done" + entity); 

    httpPost.setEntity(entity); 

    HttpResponse response = httpClient.execute(httpPost, localContext); 

} catch (IOException e) { 
    e.printStackTrace(); 
} 
} 

而且我的PHP：

<?php 

$uploads_dir = 'uploads/'; 

$uploadname = $_FILES["image"]["name"]; 
$uploadtitle = $_FILES["title"]["title"]; 


move_uploaded_file($_FILES['image']['tmp_name'], $uploads_dir.$uploadname); 
file_put_contents($uploads_dir.'juhl.txt', print_r($uploadtitle, true)); 
?> 

我是見過世面的有關MultipartEntity的其他問題，但似乎無法找到答案。我試過只發送Stringbody，但沒有任何succs。我認爲問題是服務器端（在PHP中），但任何建議都是值得歡迎的。

這是我在這裏的第一個問題 - 隨時在形式和清晰度:-)

Answer 1

的問題是我的PHP。 當您收到Stringbody時，只有一個參數（與filebody相反）。所以我刪除了第二個參數$ uploadtitle = $ _FILES [「title」] [「title」];它的工作

<?php 
$uploads_dir = 'uploads/'; 

$uploadname = $_FILES["image"]["name"]; 
$uploadtitle = $_FILES["title"]; 


move_uploaded_file($_FILES['image']['tmp_name'], $uploads_dir.$uploadname); 
file_put_contents($uploads_dir.'juhl.txt', print_r($uploadtitle, true)); 
?> 

我希望這可以幫助，如果你有同樣的問題。

評論嘗試這種方式，

  ByteArrayBody bab1 = bab11; 
     HttpClient httpClient = new DefaultHttpClient(); 
     httpPost = new HttpPost("link.php?api_name=api"); 
     MultipartEntity reqEntity = new MultipartEntity(
       HttpMultipartMode.BROWSER_COMPATIBLE); 
     // this is for String 
     try { 
      reqEntity.addPart("udid", new StringBody(UDID)); 
      } 
     catch (Exception e) 
      { 
      } 
       // this is for image upload 
      try 
      { 
       reqEntity.addPart("file1", bab1); 
      } catch (Exception e) 
      { 
      } 
       // this is for video upload 
     try {    
       if (stPath1 != null) { 
        Log.e("path 1", stPath1); 
        Log.v("stDocType1", "video"); 
        File file = new File(stPath1); 
        FileBody bin = new FileBody(file); 
        reqEntity.addPart("file1", bin); 
       } 
     } catch (Exception e) { 
     } 

      httpPost.setEntity(reqEntity); 
      ResponseHandler<String> responseHandler = new BasicResponseHandler(); 
      response = httpClient.execute(httpPost, responseHandler);
