CURL in android

2023-03-02 03:02 问答作者：

I was looking through different blogs, sites and stack overflow for my answer. I have an app which shares images with a server. They provide a API token for the authentication, and the authentication is using curl. Can any one tell me how can I use curl in my app. I have to pass url as API token + password+ the path in the same form to get authentication. Can any one suggest some tricks to get it done.?

Thanks in advance

Happy Coding

Edit

Code

 public static String getRequest() {
        StringBuffer stringBuffer = new StringBuffer("");
        BufferedReader bufferedReader = null;
        try {
            HttpClient httpClient = new DefaultHttpClient();
            HttpGet httpGet = new HttpGet();

            URI uri = new URI("http://s1.campfirenow.com/room/5e1a1/speak.xml");
            httpGet.setURI(uri);
            httpGet.addHeader(BasicScheme.authenticate(
                    new UsernamePasswordCredentials("f48be786f212f1e35dd9s265b4675358123d838e53", "X"),
                    HTTP.UTF_8, false));

            httpGet.setHeader("Content-Type", "application/xml");
            HttpResponse httpResponse = httpClient.execute(httpGet);

This is the log cat response from the server (logcat output)

Let's assume that you want to do the following request:

curl -u user:password http://sample.campfirenow.com/rooms.xml

In Android you would do as follow.

public static String getRequest() {
        StringBuffer stringBuffer = new StringBuffer("");
        BufferedReader bufferedReader = null;
        try {
            HttpClient httpClient = new DefaultHttpClient();
            HttpGet httpGet = new HttpGet();

            URI uri = new URI("http://sample.campfirenow.com/rooms.xml");
            httpGet.setURI(uri);
            httpGet.addHeader(BasicScheme.authenticate(
                    new UsernamePasswordCredentials("user", "password"),
                    HTTP.UTF_8, false));

            HttpResponse httpResponse = httpClient.execute(httpGet);
            InputStream inputStream = httpResponse.getEntity().getContent();
            bufferedReader = new BufferedReader(new InputStreamReader(
                    inputStream));

            String readLine = bufferedReader.readLine();
            while (readLine != null) {
                stringBuffer.append(readLine);
                stringBuffer.append("\n");
                readLine = bufferedReader.readLine();
            }
        } catch (Exception e) {
            // TODO: handle exception
        } finally {
            if (bufferedReader != null) {
                try {
                    bufferedReader.close();
                } catch (IOException e) {
                    // TODO: handle exception
                }
            }
        }
        return stringBuffer.toString();
    }

You can change HttpGet to HttpPost / HttpPut / HttpDelete depending on what you need to access.

Cheers.
