HTTP 错误 400。请求的 header 名称无效

Question

我有一个包含以下代码的 Java 应用程序。我正在尝试使用 HttpClient POST 调用 REST Web 服务。我需要发送自定义 header "auth" 进行身份验证。 header 的值是由“:”分隔的加密凭据。

        String strAuth = DoAESEncrypt("userid:pwd");
        String strContent = DoAESEncrypt("{\"Name\":Tester,\"Id\":\"123\",\"NickName\":null,\"IsLocked\":false}");

          HttpClient client =  new DefaultHttpClient();          
          HttpPost post = new HttpPost("https://domainname/servicename");
          post.addHeader("auth",strAuth);
          post.addHeader("Content-Type", "application/json");
          StringEntity input = new StringEntity(strContent);
          post.setEntity(input);
          HttpResponse response = client.execute(post);

DoAESEncrypt 是一个加密输入字符串和 returns 密码的函数。但是，当我运行这段代码时，出现以下错误，其中包含语句 client.execute:

HTTP Error 400. The request has an invalid header name

但是，如果我 hard-code 下面 header 使用我使用相同的 DoAESEncrypt 函数生成的加密密码，它工作正常：

      post.addHeader("auth","5PE7vNMYVFJT/tgYo7TGuPO05lqMQx5w3BAJKDS567A73vM0TYFmWO5tP=");

Answer 1

出于某种原因，DoAESEncrypt 函数在密文中添加了回车 return“\r\n”。这已被删除并且工作正常。

Answer 2

String strAuth = DoAESEncrypt("userid:pwd");
        String strContent = DoAESEncrypt("{\"Name\":Tester,\"Id\":\"123\",\"NickName\":null,\"IsLocked\":false}");

          HttpClient client =  new DefaultHttpClient();          
          HttpPost post = new HttpPost("https://domainname/servicename");
          post.addHeader("auth",strAuth.replace("\n","").replace("\r","");
          post.addHeader("Content-Type", "application/json");
          StringEntity input = new StringEntity(strContent);
          post.setEntity(input);
          HttpResponse response = client.execute(post);

Replace all \n and \r from your encrypted string which you passing to header as follow

strAuth.replace("\n","").replace("\r","")
