php用于接收来自多方关系的图像和文本

Question

我试图通过multiparentity上传图像和一些文本。我可以上传和接收图像，但是当我尝试添加Stringbody时，我似乎无法接收它。这是我的android代码

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();
}
}

And my 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));
?>

我一直围绕着关于多父性的其他问题，但似乎找不到答案。我试过只发送Stringbody，但也没有成功。我认为问题是服务器端(在PHP)，但任何建议都是欢迎的。

这是我在这里的第一个问题-请随意评论形式和清晰度:-)

试试这个方法，

         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);

问题出在php。当您接收Stringbody时，只有一个参数(与filebody相反)。所以我删除了$uploadtitle = $_FILES["title"]["title"]中的第二个参数;它成功了

<?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));
?>

如果你有同样的问题，我希望这对你有帮助。
