我有这个卷曲在java中复制

curl -i -L HTTPS：// {用户名}：{密码} @ url.com / exportsData

HTTP/1.1 302 Found

这是我的代码，它将401作为回复返回：

List<Long> ids = new ArrayList<Long>();
try (final CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
    final HttpGet httpGet = new HttpGet("https://" + username + ":"
            + password + "@url.com/exportsData");

    try (CloseableHttpResponse response = httpClient.execute(httpGet)) {

        if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
            final ObjectMapper mapper = new ObjectMapper();
            mapper.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);
            mapper.disable(DeserializationFeature.FAIL_ON_INVALID_SUBTYPE);
            ids = Arrays.asList(mapper.readValue(response.getEntity().getContent(), Long[].class));
        }
    } catch (final JsonParseException e) {
        logger.error("JsonParseException", e);
    } catch (final JsonMappingException e) {
        logger.error("JsonMappingException", e);
    } catch (final UnsupportedOperationException e) {
        logger.error("UnsupportedOperationException", e);
    } catch (final IOException e) {
        logger.error("IOException", e);
    }
} catch (final IOException e1) {
    logger.error("IOException1", e1);
}
return ids;

也以这种方式测试（总是401）

List<Long> ids = new ArrayList<Long>();
final CredentialsProvider provider = new BasicCredentialsProvider();
provider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("username", "password");
try (final CloseableHttpClient httpClient = HttpClientBuilder.create().setDefaultCredentialsProvider(provider).build()) {
    final HttpGet httpGet = new HttpGet("https://url.com/exportsData");

    try (CloseableHttpResponse response = httpClient.execute(httpGet)) {

        if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
            final ObjectMapper mapper = new ObjectMapper();
            mapper.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);
            mapper.disable(DeserializationFeature.FAIL_ON_INVALID_SUBTYPE);
            ids = Arrays.asList(mapper.readValue(response.getEntity().getContent(), Long[].class));
        }
    } catch (final JsonParseException e) {
        logger.error("JsonParseException", e);
    } catch (final JsonMappingException e) {
        logger.error("JsonMappingException", e);
    } catch (final UnsupportedOperationException e) {
        logger.error("UnsupportedOperationException", e);
    } catch (final IOException e) {
        logger.error("IOException", e);
    }
} catch (final IOException e1) {
    logger.error("IOException1", e1);
}
return ids;

还测试了添加到HttpClientBuilder

.setRedirectStrategy(new LaxRedirectStrategy()).build()

我错过了什么？

我一开始并不理解这个问题。如果下面不是问题我建议提高日志级别，看看发生了什么（https://hc.apache.org/httpcomponents-client-ga/logging.html）

- 初步解决方案 -

您需要将凭据传递给客户端，而不是将其添加到网址。

curl - 使用Java定位
