android - 如何使用 AndroidHttpClient(API 级别 8)和 UsernamePasswordCredentials？

Question

目前我正在使用 DefaultHttpClient 和 ThreadSafeClientConnManager。这工作正常，但我想用 AndroidHttpClient 替换它。不幸的是，我无法添加目前对我很重要的 UsernamePasswordCredentials。任何人都可以提供提示或解决方案吗？

您需要使用HttpRequestInterceptor 类进行身份验证。

举个例子

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);
            }
        }
    }    
};
