在Android中发送“PUT”请求以休息api

我有一个android应用程序，可以在Web服务中进行咨询和插入。所有这一切都通过Apache HTTPClient和JSON。在Android中发送“PUT”请求以休息api

所以例如我插入一个新的用户到数据库。

HttpClient httpclient = new DefaultHttpClient(); 
     // 2. make POST request to the given URL 
      HttpPost httpPost = new HttpPost(url); 
      String json = ""; 
      // 3. build jsonObject 
      JSONObject jsonObject2 = new JSONObject(); 
      jsonObject2.put("name", name); 
      jsonObject2.put("number", num); 
     // 4. convert JSONObject to JSON to String 
      json = jsonObject.toString(); 
     // 5. set json to StringEntity 
      StringEntity se = new StringEntity(json); 
     // 6. set httpPost Entity 
      httpPost.setEntity(se); 
     // 7. Set some headers to inform server about the type of the content 
      httpPost.setHeader("Accept", "application/json"); 
      httpPost.setHeader("Content-type", "application/json"); 
      // 8. Execute POST request to the given URL 
      HttpResponse httpResponse = httpclient.execute(httpPost);

都完全建立，现在好了，我想用我的REST API创建的方法，方法PUT覆盖例如ID为5的用户的名称。如果我想要做一大家进入我的网址+/ID并获取特定用户。到“PUT”我这样做，但不起作用。

@Override 
    protected String doInBackground(String... params) { 
     InputStream inputStream = null; 
     String result = ""; 

     try { 
      // 1. create HttpClient 
      HttpClient httpclient = new DefaultHttpClient(); 
      // 2. make POST request to the given URL 

      HttpPut httpPut = new  
      HttpPut("http://000.000.0.000:0000/xxxxxx/webresources/net.xxxxx.users/5"); 
      String json = ""; 
      //    // 3. build jsonObject 
      //    JSONObject jsonObject2 = new JSONObject(); 
      //    jsonObject2.put("idGuarderias", idG); 
      // 3. build jsonObject 
      JSONObject jsonObject = new JSONObject(); 
      jsonObject.put("name",newName); 
      //  jsonObject.put("guarderiasIdGuarderias",jsonObject2); 
      json = jsonObject.toString(); 
      StringEntity se = new StringEntity(json); 
      // 6. set httpPost Entity 
      httpPut.setEntity(se); 
      // 7. Set some headers to inform server about the type of the content 
      httpPut.addHeader("Accept", "application/json"); 
      httpPut.addHeader("Content-type", "application/json"); 
      // 8. Execute POST request to the given URL 
      HttpResponse httpResponse = httpclient.execute(httpPut); 

     } catch (Exception e) { 
      Log.d("InputStream", e.getLocalizedMessage()); 
     }

我应该做什么改变？

有什么错误？ – 2014-09-11 08:31:31

不，不要在bd里输入任何东西... – 2014-09-11 08:35:53

也没有例外吗？很奇怪，它是否是正确的URL？ – 2014-09-11 08:39:18

我解决我的问题与下面的代码，感谢回答。

@Override 
    protected String doInBackground(String... params) { 
     InputStream inputStream = null; 
     String result = ""; 

     try { 
      // 1. create HttpClient 
      HttpClient httpclient = new DefaultHttpClient(); 
      // 2. make POST request to the given URL 
      HttpPut httpPUT = new  
        HttpPut("http://xxx.xx.x.xxx:xxxx/xxxxxxxy/webresources/net.xxxxxx.users/3"); 
      String json = ""; 
      // 3. build jsonObject 
      JSONObject jsonObject = new JSONObject(); 
      jsonObject.put("idUser","3"); 
      jsonObject.put("name","Mark"); 
      jsonObject.put("pass","1234"); 
      jsonObject.put("rol","554"); 
      jsonObject.put("usuario","mark"); 




      // 4. convert JSONObject to JSON to String 
      json = jsonObject.toString(); 

      // 5. set json to StringEntity 
      StringEntity se = new StringEntity(json); 
      // 6. set httpPost Entity 
      httpPUT.setEntity(se); 
      // 7. Set some headers to inform server about the type of the content 
      httpPUT.setHeader("Accept", "application/json"); 
      httpPUT.setHeader("Content-type", "application/json"); 
      // 8. Execute POST request to the given URL 
      HttpResponse httpResponse = httpclient.execute(httpPUT); 
      // 9. receive response as inputStream 
      //     inputStream = httpResponse.getEntity().getContent(); 
      //     // 10. convert inputstream to string 
      //     if(inputStream != null) 
      //      result = convertInputStreamToString(inputStream); 
      //     else 
      //      result = "Did not work!"; 
     } catch (Exception e) { 
      Log.d("InputStream", e.getLocalizedMessage()); 
     } 

     return "EXITO!"; 
    }

他们应该把网址中的ID，并覆盖所有参数，包括ID

试试这个代码：您可以在JSONObject的对象添加参数

JSONObject jsonObject = new JSONObject(); 
jsonObject.put("name",newName); 
try { 
    HttpResponse response; 
    HttpParams httpParameters = new BasicHttpParams(); 
    HttpConnectionParams.setConnectionTimeout(httpParameters, TIMEOUT); 
    HttpConnectionParams.setSoTimeout(httpParameters, TIMEOUT); 
    HttpClient httpClient = new DefaultHttpClient(httpParameters); 
    HttpPut putConnection = new HttpPut(url); 
    putConnection.setHeader("json", jsonObject.toString()); 
    StringEntity se = new StringEntity(jsonObject.toString(), "UTF-8"); 
    se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, 
      "application/json")); 
    putConnection.setEntity(se); 
    try { 
     response = httpClient.execute(putConnection); 
     String JSONString = EntityUtils.toString(response.getEntity(), 
       "UTF-8"); 
    } catch (ClientProtocolException e) { 
     e.printStackTrace(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
} catch (Exception e) { 
    e.printStackTrace(); 
}

谢谢，但我写的例子 - （“name”，newName）; putConenction.setHeader（“name”，newName）中的 – 2014-09-11 08:50:41

; ???? – 2014-09-11 08:52:58

@egh你想添加什么？基本身份验证？或者添加JSON参数？ – 2014-09-11 09:03:40

也许你可以试试这个：

@Override 
protected String doInBackground(String... params) { 
    InputStream inputStream = null; 
    String result = ""; 

    try { 
     // 1. create HttpClient 
     HttpClient httpclient = new DefaultHttpClient(); 
     // 2. make POST request to the given URL 

     HttpPut httpPut = new  
     HttpPut("http://000.000.0.000:0000/xxxxxx/webresources/net.xxxxx.users/5"); 
     String json = ""; 
     //    // 3. build jsonObject 
     //    JSONObject jsonObject2 = new JSONObject(); 
     //    jsonObject2.put("idGuarderias", idG); 
     // 3. build jsonObject 
     JSONObject jsonObject = new JSONObject(); 
     jsonObject.put("name",newName); 
     //  jsonObject.put("guarderiasIdGuarderias",jsonObject2); 
     json = jsonObject.toString(); 
     StringEntity se = new StringEntity(json); 
     // 6. set httpPost Entity 
     httpPut.setEntity(se); 
     // 7. Set some headers to inform server about the type of the content 
     httpPut.addHeader("Accept", "application/json"); 
     httpPut.addHeader("Content-type", "application/json"); 
     // 8. Execute POST request to the given URL 
     HttpResponse httpResponse = httpclient.execute(httpPut); 


     //Try to add this 
     inputStream = httpResponse.getEntity().getContent(); 

     if(inputStream != null) 
      result = convertInputStreamToString(inputStream); 
     else 
      result = "Did not work!"; 

    } catch (Exception e) { 
     //Log.d("InputStream", e.getLocalizedMessage()); 
    } 
    return result; 
}

谢谢，但是这不会覆盖我的bd中ID为5的用户的值“name”。 – 2014-09-11 09:59:19

希望这有助于一些之一：注意这里authToken是可选

public JSONObject makePutRequest(String path, String params, String authToken) { 

    try { 
     //instantiates httpclient to make request 
     @SuppressWarnings("deprecation") 
     DefaultHttpClient httpclient = new DefaultHttpClient(); 

     //url with the post data 
     @SuppressWarnings("deprecation") 
     HttpPut httpost = new HttpPut(path); 
     if (authToken != null) { 
      httpost.setHeader("X-Auth-Token", authToken); 
     } 
     //passes the results to a string builder/entity 
     @SuppressWarnings("deprecation") 
     StringEntity se = new StringEntity(params.toString()); 

     //sets the post request as the resulting string 
     httpost.setEntity(se); 
     //sets a request header so the page receving the request 
     //will know what to do with it 
     httpost.setHeader("Accept", "application/json"); 
     httpost.setHeader("Content-type", "application/json"); 
     response = httpclient.execute(httpost); 
     HttpEntity entity = response.getEntity(); 
     is = entity.getContent(); 

     if (is != null) { 

      BufferedReader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"), 8); 
      StringBuilder sb = new StringBuilder(); 
      String line = null; 
      while ((line = reader.readLine()) != null) { 
       sb.append(line + "\n"); 
      } 
      is.close(); 
      result = sb.toString(); 
     } 
     jsonObject = new JSONObject(result); 
     Log.i("Response", "" + jsonObject.toString()); 
    } catch (ClientProtocolException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } catch (JSONException e) { 
     e.printStackTrace(); 
    } 
    return jsonObject;

这里是我的码。

添加依赖于gradle这个

编译 'com.squareup.okhttp：okhttp：2.6.0'
