發出HTTP POST調用與文件

Question

我試圖做一個HTTP POST調用上傳文件（也有以填補參數的前冠軍。），以RESTful Web服務：

這是我想做：

File file = new File(filepath); 

    HttpClient client = new DefaultHttpClient(); //DefaultHTTPClient is deprecated? 
    HttpPost post = new HttpPost(url); 

    //Multipart Entity is also deprecated?? 
    MultipartEntity entity = new MultipartEntity(); 
    entity.addPart("file[path]", new FileBody(file)); 
    post.setEntity((HttpEntity) entity); 

    try { 
     HttpResponse response = client.execute(post); 

    } catch (IOException e) { 

     e.printStackTrace(); 
    } 

這是行不通的。我不知道如何上傳文件並添加參數並撥打電話？我試過用Java Http Client to upload file over POST這個，但他/她使用的是不贊成的？我有httpcore 4.4 alpha jar

是的，您使用的類已被棄用。試試下面這個例子：
