＆QUOT; HttpDeleteWithBody＆QUOT;不从数据库中删除 [英] "HttpDeleteWithBody" isn't deleted from Database

问题描述

我想打电话给我的 API 发送 JSON 为的删除 从我的数据库产品;的但是，它不会删除任何东西。的

I'm trying to call to my API sending a JSON to delete a product from my DB; however, it doesn't delete anything.

的的 JSON 是响应真，它并没有给我任何错误;即便如此，当我做我的数据库查询，该产品仍然存在。的

The response of the JSON is "true," and it doesn't give to me any error; even so, when I make a query on my DB, the product is still there.

我已经创建了一个名为类 HttpDeleteWithBody ，看起来像：

I've created a class called HttpDeleteWithBody that looks like:

class HttpDeleteWithBody extends HttpEntityEnclosingRequestBase {
    public static final String METHOD_NAME = "DELETE";
    public String getMethod() { return METHOD_NAME; }

    public HttpDeleteWithBody(final String uri) {
        super();
        setURI(URI.create(uri));
    }
    public HttpDeleteWithBody(final URI uri) {
        super();
        setURI(uri);
    }
    public HttpDeleteWithBody() { super(); }
}

然后在我的 doInBackGround 我的片段，我这样做：

boolean resul = true;
try {
    JSONObject usuari = new JSONObject();
    try {
        usuari.put("idProducte", params[0]);
        usuari.put("idusuari", params[1]);
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    try {
        HttpEntity entity = new StringEntity(usuari.toString());
        HttpClient httpClient = new DefaultHttpClient();
        HttpDeleteWithBody httpDeleteWithBody = new HttpDeleteWithBody(getResources().getString(R.string.IPAPI) + "produsuaris/produsuari");
        httpDeleteWithBody.setEntity(entity);

        HttpResponse response = httpClient.execute(httpDeleteWithBody);
        Log.d("Response ---------->", response.getStatusLine().toString());
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
} catch (Exception ex) {
    Log.e("ServicioRest", "Error!", ex);
}
return resul;

此外，我试图做到这一点：

Furthermore, I've tried to do this:

HttpDeleteWithBody delete = new HttpDeleteWithBody(getResources().getString(R.string.IPAPI) + "produsuaris/produsuari");
StringEntity se = new StringEntity(usuari.toString(), HTTP.UTF_8);
se.setContentType("application/json");

delete.setEntity(se);

但是，它不工作...日志说：

however, it doesn't work... the log says:

D /响应---------->：HTTP / 1.1 200 OK

D/Response ---------->﹕ HTTP/1.1 200 OK

这是我如何调用该方法：

This is how I call the method:

JSONObject deleteproduct = new JSONObject();
try {
    deleteproduct.put("idProducte", String.valueOf(IDPROD));
    deleteproduct.put("idusuari", String.valueOf(IDUSU));
} catch (JSONException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
Log.i("Json test per afegir prod --> ", deleteproduct.toString());
TareaWSInsertar tarea = new TareaWSInsertar();
tarea.execute(String.valueOf(IDPROD), String.valueOf(IDUSU));

的我在我的谷歌浏览器添加一个插件叫做<一个href=\"https://chrome.google.com/webstore/detail/postman-rest-client/fdmmgilgnpjigdojojpjoooidkmcomcm\"相对=nofollow>邮递员的，当我试图通过这种方式来做到这一点，它的正确删除...

I've added on my Google Chrome a plug-in called "PostMan" and when I try to do this by this way, it's deleting correctly...

我在做什么错了？

我试图用卷曲，这是结果：

的它返回我假的，当我把同样的 JSON 为邮递员;不过，如果我把同样的 JSON 在邮递员，它工作正常。的

It is returning me false, when I put the same JSON as PostMan; nevertheless, if I put the same JSON on PostMan, it works fine.

我实现离子库我也喜欢它：

 JSONObject usuari = new JSONObject();
            try {
                usuari.put("idProducte", params[0]);
                usuari.put("idusuari", params[1]);
            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            try {
                String url = getResources().getString(R.string.IPAPI) + "produsuaris/produsuari";
                Log.d("CURL", "curl -X DELETE -d '" + usuari.toString() + "' " + url);

                Builders.Any.F builder = Ion.with(getActivity().getApplicationContext())
                        .load(HttpDelete.METHOD_NAME, url)
                        .setTimeout(15000).setStringBody(usuari.toString());


                String response = builder.toString();
                Log.d("TEST", "Req response -->" + response);
            }
            catch (Exception ex){
                resul = false;
            }

和它仍然返回它的确定，不删除任何东西。

And it still returning that it's OK, and don't delete anything.

推荐答案

我终于解决了这个问题，我所做的是改变我的<$的 HttpDelete 方法C $ C API 和>，而不是发送一个 JSON ，我送参数（如 HTTPGET ），现在我的code是这样的：

Finally I solved the problem, what I've done is change the HttpDelete method on my API, and instead of send a JSON, I send parameters (like a HttpGet) and now my code is like :

   boolean resul = true;

        HttpClient httpClient = new DefaultHttpClient();

        String id____USER = params[0];
        String id____PROD = params[1];

        HttpDelete del =
                new HttpDelete(getResources().getString(R.string.IPAPI) + "produsuaris/produsuari?idProd=" + Integer.parseInt(id____PROD)+"&idUs="+Integer.parseInt(id____USER));

        del.setHeader("content-type", "application/json");

        try
        {
            HttpResponse resp = httpClient.execute(del);
            String respStr = EntityUtils.toString(resp.getEntity());

            if(!respStr.equals("true"))
                resul = false;
        }
        catch(Exception ex)
        {
            Log.e("ServicioRest","Error!", ex);
            resul = false;
        }

        return resul;

这是我如何把这个 AsyncMethod

  TareaWSInsertar tarea = new TareaWSInsertar();
                                tarea.execute(String.valueOf(IDUSU),String.valueOf(IDPROD));

这工作对我来说，我知道这是不是最好的解决办法，但我没有太多的时间，还我试过三种解决方案，并没有人没有工作。

This work to me, I know it's not the best solution, but I've no much time, also I tried three solutions and noone didn't work.

随意张贴一个正确的答案，如果你知道我在做什么错了。
