Question

我正在做的应该是一个简单的http帖子，其中包含一个json字符串作为http正文。

？ enter image description here

除响应本身外，所有看起来都很好 - 当我把它变成一个字符串时，它看起来很奇怪（不是文本）。我怎么用纯文本来得到这个？或者在帖子中我做错了什么来得到这个回复？（注意 - 如果我在POST期间排除了cookie，我会从服务器上获得普通的html，并提供有效的“拒绝访问”消息）

此解决方案的完整代码位于

public class BaseHttpService {
    public ResponseAndCookies doHttpPostWithUrlWithJson(String url, String key, CookieStore cookies) {
        try {
            StringEntity se = new StringEntity("{\"filters\":true}");
            se.setContentType("text/xml");
            se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));

            HttpPost httpost = new HttpPost(url);
            httpost.setEntity(se);

            httpost.setHeader("Accept", "application/json");
            httpost.setHeader("Content-Type", "application/json");

            return executeHttpRequest(httpost, cookies);
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        return null;
    }

    public ResponseAndCookies executeHttpRequest(HttpRequestBase http, CookieStore cookieStore) {
        HttpClient httpclient = new DefaultHttpClient();
        HttpResponse response;
        String result = "";

        if (cookieStore != null) {
            ((DefaultHttpClient) httpclient).setCookieStore(cookieStore);
        }

        try {
            response = httpclient.execute(http);

            HttpEntity entity = response.getEntity();

            if (entity != null) {
                InputStream instream = entity.getContent();
                result = convertStreamToString(instream);
            }

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

        List<Cookie> cookies = ((DefaultHttpClient) httpclient).getCookieStore().getCookies();
        CookieStore postCookieStore = ((DefaultHttpClient) httpclient).getCookieStore();

        ResponseAndCookies x = new ResponseAndCookies();
        x.setCookies(cookies);
        x.setResponse(result);
        x.setCookieStore(postCookieStore);

        httpclient.getConnectionManager().shutdown();

        return x;
    }

    public static String convertStreamToString(InputStream is) {
        BufferedReader reader = new BufferedReader(new InputStreamReader(is));
        StringBuilder sb = new StringBuilder();
        String line = null;
        try {
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                is.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return sb.toString();
    }
}

您尝试使用平台编码读取UTF-8字符串。找出返回响应的内容编码，并使用它转换为字符串。

如果您想用2行代码替换上面的代码，请告诉我。我为你准备了一个项目，它已经处理了cookie并转换了内容。
