Question

目前我正在使用带有ThreadSafeClientConnManager的DefaultHttpClient。这很好用，但我想用AndroidHttpClient替换它。很遗憾，我无法添加对我来说很重要的UsernamePasswordCredentials。任何人都可以提供提示或解决方案吗？

Answer 1

您需要使用HttpRequestInterceptor类进行身份验证。

这是一个例子

HttpRequestInterceptor httpRequestInterceptor = new HttpRequestInterceptor() {
    public void process(final HttpRequest request, final HttpContext context) throws HttpException, IOException {
        AuthState authState = (AuthState) context.getAttribute(ClientContext.TARGET_AUTH_STATE);
        CredentialsProvider credsProvider = (CredentialsProvider) context.getAttribute(
                ClientContext.CREDS_PROVIDER);
        HttpHost targetHost = (HttpHost) context.getAttribute(ExecutionContext.HTTP_TARGET_HOST);

        if (authState.getAuthScheme() == null) {
            AuthScope authScope = new AuthScope(targetHost.getHostName(), targetHost.getPort());
            Credentials creds = credsProvider.getCredentials(authScope);
            if (creds != null) {
                authState.setAuthScheme(new BasicScheme());
                authState.setCredentials(creds);
            }
        }
    }    
};

我知道这个问题很老但是为了任何绊脚石的人（就像我一样），你可以用HttpGet对象自己滚动标题。像这样：

httpGet.addHeader("Authorization", "Basic " + Base64.encode(username+":"+password));

对Saad Farooq的答案进行了一些改进，以下代码适用于我。

final AndroidHttpClient client = AndroidHttpClient.newInstance("Android");

getRequest = new HttpGet(url);

getRequest.addHeader("Authorization", "Basic " + Base64.encodeToString(new
                String(username + ":" + password).getBytes(), Base64.NO_WRAP));

如何使用AndroidHttpClient（API Level 8）和UsernamePasswordCredentials？
