我只是在玩 Asana API。因此,每当我提出请求时,我总是会收到 Bad Request 错误。

所以我得到的是:

public class Asana {

    private static String apiKey;
    private DefaultHttpClient httpClient;
    private final String apiUrl = "https://app.asana.com/api/1.0/";

    public Asana(String key) {
        apiKey = key;
        httpClient = new DefaultHttpClient();
    }

    public void get(String target) {
        new APIRequest().execute(target);
    }

    private class APIRequest extends AsyncTask<String, Void, HttpResponse> {

        protected HttpResponse doInBackground(String... params) {
            String query = apiUrl + params[0];

            Log.d("#query", query);

            HttpGet get = new HttpGet(query);
            String cred = apiKey + ':';
            String encodedKey = Base64.encodeToString(cred.getBytes(), Base64.DEFAULT);

            Log.d("#encodedKey", encodedKey);

            get.setHeader("Authorization", "Basic " + encodedKey);
            get.setHeader("Content-Type", "application/json; charset=UTF-8");

            Log.d("#getRequestLine", get.getRequestLine().toString());

            /*httpClient.getCredentialsProvider().setCredentials(
                    new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT, AuthScope.ANY_REALM, AuthPolicy.BASIC),
                    new UsernamePasswordCredentials(apiKey, "")
            );*/

            HttpResponse resp = null;
            try {
                resp = httpClient.execute(get);
            } catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } finally {
                httpClient.getConnectionManager().shutdown();
            }

            return resp;
        }

        protected void onPostExecute(HttpResponse response) {
            StatusLine statusLine = response.getStatusLine();
            ByteArrayOutputStream out = new ByteArrayOutputStream();

            Log.d("#statusLine", statusLine.toString());

            try {
                response.getEntity().writeTo(out);
            } catch (IOException e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            }

            Log.d("#out", out.toString());
        }
    }

}

使用 cURL 或 Simple REST 客户端(Chrome),我能够得到正确的结果。

我对上面的代码做错了吗?

好的,所以我自己解决了这个问题。我认为问题出在身份验证上。

我现在使用的是以下命令,而不是手动设置 Authorization 标头:

get.addHeader(BasicScheme.authenticate(new UsernamePasswordCredentials(apiKey, ""), "US-ASCII", false));

它现在工作正常,我可以得到正确的结果。

如果有人感兴趣,在 github 上有一个用于 Asana API的 Java库。
