Question

捲曲--location我有這樣的捲曲在Java中複製

捲曲-i -L 的https：// {用戶名} {}密碼@ url.com/exportsData

響應

這是我的代碼返回我401響應：

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; 

以這種方式（總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; 

還測試增加HttpClientBuilder

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

我已經錯過了還測試？

我一開始並不理解這個問題。如果下面不是問題，我建議殺青日誌級別，看看發生了什麼（https://hc.apache.org/httpcomponents-client-ga/logging.html）

- 最初的解決方案 -

你需要傳遞的，而不是將它們添加到憑據到客戶端網址。
