Android：从 https url 获取响应

发布于 2024-10-04 05:09:41 字数 155 浏览 2 评论 0原文

您好，

我正在开发一个 Android 应用程序，需要通过 https 打开一个 url（带有 POST 参数）并获取响应。

我有一个自签名证书，这让情况更加复杂。我还需要接受cookies。

有人知道从哪里开始吗？

预先非常感谢，

Android 附带了 apache commons http 库。
设置 https post 请求非常简单：

HttpPost post = new HttpPost("https://yourdomain.com/yourskript.xyz");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("postValue1", "my Value"));
nameValuePairs.add(new BasicNameValuePair("postValue2", "2nd Value"));
post.setEntity(new UrlEncodedFormEntity(nameValuePairs));

HttpClient client = new DefaultHttpClient();
HttpResponse response = client.execute(post);
HttpEntity entity = response.getEntity();

String responseText = EntityUtils.toString(entity);

Android 使用 commons http 库的 4.x 版本，因为 4.0 以下的所有版本都已超出其生命周期。

我无法准确说明如何将自签名证书注册到 HttpClient，但我的公共 http 文档会有所帮助：

Android comes with the apache commons http library included.
Setting up a https post request is quite easy:

HttpPost post = new HttpPost("https://yourdomain.com/yourskript.xyz");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("postValue1", "my Value"));
nameValuePairs.add(new BasicNameValuePair("postValue2", "2nd Value"));
post.setEntity(new UrlEncodedFormEntity(nameValuePairs));

HttpClient client = new DefaultHttpClient();
HttpResponse response = client.execute(post);
HttpEntity entity = response.getEntity();

String responseText = EntityUtils.toString(entity);

Android uses a version 4.x of the commons http library as all versions below 4.0 are out of their lifecycle.

I can't tell exactly how to register a self-signed certificate to the HttpClient, but mybe the commons http documentation helps:

我设法使用 cookie 和未签名的 https 使其全部异步工作。

我在这里使用了代码：

http ://masl.cis.gvsu.edu/2010/04/05/android-code-sample-asynchronous-http-connections/

并使用 Brian Yarger 的代码修改为未签名的 https：

Android 上的自签名 SSL 接受

（将上述代码添加到 HttpConnection.java 中 run() 的开头）

为了让 cookies 工作，我必须修改一些代码（来自 HttpConnection.java 的 POST 片段）：

         case POST:
            HttpPost httpPost = new HttpPost(url);
            httpPost.setEntity(new StringEntity(data));
            httpPost.addHeader("Cookie", Cookie.getCookie());
            response = httpClient.execute(httpPost);

            Header[] headers=response.getAllHeaders();
            for(int i=0;i<headers.length;i++){
                if(headers[i].getName().equalsIgnoreCase("Set-Cookie")){
                    //Log.i("i",headers[i].getName()+"---"+headers[i].getValue());
                    Cookie.setCookie(headers[i].getValue());
                    break;
                }
            }
            break;

非常感谢大家为我指明了方向，

I managed to get it all working asyncronously with both cookies and unsigned https.

I used the code here:

http://masl.cis.gvsu.edu/2010/04/05/android-code-sample-asynchronous-http-connections/

and modified for unsigned https using Brian Yarger's code here:

Self-signed SSL acceptance on Android

(Add the above code to the beginning of run() in HttpConnection.java)

To get the cookies to work, I had to modify some code (POST snippet from HttpConnection.java):

         case POST:
            HttpPost httpPost = new HttpPost(url);
            httpPost.setEntity(new StringEntity(data));
            httpPost.addHeader("Cookie", Cookie.getCookie());
            response = httpClient.execute(httpPost);

            Header[] headers=response.getAllHeaders();
            for(int i=0;i<headers.length;i++){
                if(headers[i].getName().equalsIgnoreCase("Set-Cookie")){
                    //Log.i("i",headers[i].getName()+"---"+headers[i].getValue());
                    Cookie.setCookie(headers[i].getValue());
                    break;
                }
            }
            break;

Many thanks to everyone for pointing me in the direction,
