Question

当我尝试运行某些代码时，我收到以下错误：

The method parse() is undefined for the type HttpResponse

这是我的代码：

post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = client.execute(post);
strResp = EntityUtils.toString(response.getEntity());
Document document = response.parse();

Answer 1

parse()

没有此类方法HttpResponse

Answer 2

为什么要解析HttpResponse？它不存在......对于String存在Parse 也许你想做：

Document document = strResp.parse();

如果strResp是一个String，那将会有效。但也许这不是你想要的。

我是这样做的（我在网上找到了它，它对我来说很完美）：

    public String getXmlFromUrlHttp(String url)  
{
    String xml = null;

    try {
        // defaultHttpClient            
        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpGet httpPost = new HttpGet(url);
        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity httpEntity = httpResponse.getEntity();
        xml = EntityUtils.toString(httpEntity);

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

    return xml;
}

然后解析函数的结果;）

Answer 3

我认为你应该从How to parse a xml type HTTPResponse in Android

获得一些解决方案

可能类似于：

...
post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = client.execute(post);
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
InputStream is = response.getEntity().getContent();
Document doc = db.parse(is);

错误：对于HttpResponse类型，未定义方法parse（）
