HttpResponse和BufferedReader

Question

我正在尝试读取缓冲区（Android应用程序）并将其值设置为TextView 'httpStuff' 。 但是我不认为我从URI得到了一些回应。

我没有任何运行时错误。 我尝试了许多具有相同逻辑的风格。 似乎没有任何作用。

清单中已经设置了INTERNET权限。 SdkVersion="15" 。 有什么帮助吗？

HttpClient client = new DefaultHttpClient();
URI website = new URI("http://www.mybringback.com");
HttpGet request = new HttpGet();
request.setURI(website);
HttpResponse response = client.execute(request);
HttpEntity entity = response.getEntity(); 
InputStream is = entity.getContent(); 
BufferedReader in = new BufferedReader(new InputStreamReader(is));

httpStuf.setText( in.readLine());

Answer 1

我认为您丢失了while循环，并且当您仅在in.readLine()说时，可能是它从响应中返回了空行，尽管它具有足够的数据。所以请确保像并检查其内容。

while ((line = rd.readLine()) != null) {
    httpStuf.setText(line+"\r\n");
}

希望这会帮助你。

Answer 2

这段代码对我有用

  InputStream is = response.getEntity().getContent();
  String strResponse = inputStreamToString(is);


private String inputStreamToString(InputStream is)
{

    String line = "";
    StringBuilder total = new StringBuilder();
    // Wrap a BufferedReader around the InputStream
    BufferedReader rd = new BufferedReader(new InputStreamReader(is), 1024 * 4);
    // Read response until the end
    try
    {

        while ((line = rd.readLine()) != null)
        {
            total.append(line);
        }
    } catch (IOException e)
    {
        Log.e(TAG, "error build string" + e.getMessage());
    }
    // Return full string
    return total.toString();
}

尝试获取response的状态码，然后可以与（ HTTP status ）比较

int responseCode=response.getStatusLine().getStatusCode()

Answer 4

我使用这种方法只是捕获HTTP响应，对我来说很好用。

public String httpGetResponse(String url) {
        try {
            Log.i("HTTP Request", "httpGet Request for : " + url);
            DefaultHttpClient client = new DefaultHttpClient();
            HttpGet get = new HttpGet(url);
            //get.setHeader("Connection", "keep-alive");

            HttpResponse response = client.execute(get);

            InputStream is = response.getEntity().getContent();
            BufferedReader bufferedReader = new BufferedReader(
                    new InputStreamReader(is));
            StringBuilder str = new StringBuilder();

            String line = null;

            while ((line = bufferedReader.readLine()) != null) {
                str.append(line + "\n");
            }
            return str.toString();
        } catch (Exception e) {
            Log.e("HTTP error", "Error in function httpGetResponse : "
                    + e.getMessage());
            return null;
        }
    }
