Question

我有一个休息控制器在http://localhost:8080/documents回答。我应该有一个授权标题来调用它。

所以在我的客户端代码中我有：

HttpHeaders headers = new HttpHeaders();
headers.set(HttpHeaders.AUTHORIZATION, "myToken");
HttpEntity entity = new HttpEntity(null, headers);

restTemplate = new RestTemplate();
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
restTemplate.getMessageConverters().add(new StringHttpMessageConverter());

response = restTemplate.exchange("http://localhost:8080/documents", HttpMethod.GET, entity, Document[].class);

一切正常。之后我想测试错误。所以，我删除了授权标题。

当我使用像邮递员这样的工具进行测试时，我会收到401响应。但是使用我的其余模板，我只收到IllegalArgumentException。

我已经测试了ResponseErrorHandler。

public class MyErrorHandler implements ResponseErrorHandler {

    @Override
    public boolean hasError(ClientHttpResponse clientHttpResponse) throws IOException {
        return false; //i've also tried return true
    }

    @Override
    public void handleError(ClientHttpResponse clientHttpResponse) throws IOException {
        String theString = IOUtils.toString(clientHttpResponse.getBody());
        FunctionalTestException exception = new FunctionalTestException();
        Map<String, Object> properties = new HashMap<String, Object>();
        properties.put("code", clientHttpResponse.getStatusCode().toString());
        properties.put("body", theString);
        properties.put("header", clientHttpResponse.getHeaders());
        exception.setProperties(properties);
        throw exception;
    }
}

在我的客户中我有

restTemplate.setErrorHandler(new MyErrorHandler());

它不起作用。

所以我的问题是如何使用其余模板找到我的401错误响应。

以下是例外：

java.lang.IllegalArgumentException: invalid start or end

崩溃发生在HttpURLConnection::getHeaderField，因此我怀疑您的某个响应标头格式不正确（而不是HttpURLConnection预期的那样）。通常，401响应附带WWW-Authenticate响应标头，将代理指向服务支持的身份验证方法。我怀疑这个标题会导致崩溃。

泽西岛问题跟踪器中的

A bug report显示HttpURLConnection对WWW-Authentication标头格式施加了一些限制。在这种特殊情况下，导致类似崩溃的值为oauth_problem=token_rejected。提出的解决方法是：

解决方法是发送有效的标头值（符合规范）或使用ApacheConnector
