Question

我尝试登录网站并存储Cookie，以便进一步验证请求。

我成功登录网站并获得回复，但我无法正确存储Cookie。这是我用来登录的代码：

private String makePostRequest(String url, List<String> header_fields, List<String> header_values) {

    String sessionCookie = "";

    HttpResponse response = null;
    HttpClient httpClient = new DefaultHttpClient();
    HttpPost httpPost = new HttpPost(url);

    //Post Data
    List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(header_fields.size());

    for(int i = 0; i < header_fields.size(); i++){

        nameValuePair.add(new BasicNameValuePair(header_fields.get(i), header_values.get(i)));
    }
    //Encoding POST data
    try {
        httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair));
    } catch (UnsupportedEncodingException e) {
        // log exception
        e.printStackTrace();
    }

    //making POST request.
    try {
        response = httpClient.execute(httpPost);
        // write response to log
        Log.d("Http Post Response:", response.toString());
    } catch (ClientProtocolException e) {
        // Log exception
        e.printStackTrace();
    } catch (IOException e) {
        // Log exception
        e.printStackTrace();
    }

    int statusCode = response.getStatusLine().getStatusCode();
    InputStream is = null;
    StringBuilder stringBuilder = new StringBuilder();
    if (statusCode == HttpStatus.SC_OK) {
        HttpEntity entity = response.getEntity();
        if (entity != null) {
            try {
                is = entity.getContent();
            } catch (IllegalStateException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
            byte[] buffer = new byte[1024];
            int length;
            try {
                while ((length = is.read(buffer)) > 0) {
                    stringBuilder.append(new String(buffer, 0, length));
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

     return stringBuilder.toString();
}

使用该代码我登录并获取响应字符串，我可以看到我已成功登录。有关cookie的任何想法吗？无法设法让它发挥作用。

更新

这是我用来获取会话cookie的代码

HttpGet httpGet = new HttpGet(url);
Header[] header=response.getHeaders("Set-Cookie");
for(int i =0; i < header.length; i++) {
     httpGet.addHeader("Set-Cookie", (header[i].getValue()));
}

Answer 1

从HTTP响应中获取cookie

Header[] mCookies = response.getHeaders("cookie");

在以下行之后

response = httpClient.execute(httpPost);

Answer 2

当您在共享首选项中请求第一个时间存储cookie时

date -r

发送另一个请求时

for (int i = 0; i < headers.length; i++) {
                    Header h = headers[i];
                    if (h.getName().equals("Set-Cookie")) {
                        cookie = h.getValue();
                         break;
                    }
                }

谢谢

在这里，我找到了适合我的解决方案。我使用的Wordpress API。

     @Override
                    public void success(JsonObject jsonObject, Response response) {


                        List<Header> mCookies = response.getHeaders();

                        for (int i = 0; i <mCookies.size() ; i++) {
                            mCookies.get(i).getName();

                            Log.e("response-value", String.valueOf(mCookies.get(i).getName()) +":"+ String.valueOf(mCookies.get(i).getValue()));

                            if (mCookies.get(i).getName().equals("set-cookie")){
                                Log.e("response-value", String.valueOf(mCookies.get(i).getValue()));
                            }
                        }


                        }

                    }

在邮寄请求后获取cookie
