Android：访问 RESTful Web 服务时出现 400 错误代码

发布于 2024-12-09 04:35:20 字数 825 浏览 0 评论 0原文

我想访问 Restful Web 服务。我希望请求应采用以下格式。

GET /API/Contacts/username HTTP/1.1 
HOST: $baseuri:port 
Accept: text/xml 
Authorization: Basic ZmF0aWdhYmxlIGdlbmVyYXR=

我还通过 HTTPS 协议调用 Web 服务。以下是我正在使用的代码：

HttpGet get = new HttpGet("https://secure.myapp.com/MyApp/API/Contacts/myname");

  get.addHeader("Accept","text/xml");
  get.addHeader("Authorization","Basic ZmF0aWdhYmxlIGdlbmVyYXR=");          
  get.addHeader("Host","https://secure.myapp.com");
  get.addHeader("Connection Use","HTTP 1.1");

  DefaultHttpClient client =  new DefaultHttpClient();
  ResponseHandler objHandler = new BasicResponseHandler();
  String getResponse = client.execute(get,objHandler);

但我收到错误：400 错误请求。

我不确定我的代码是否正确。是否需要在标头中显式指定方法（GET、POST 或 PUT）？

请帮我... 想你....

I want to access a Restful web service. I want the request should be in the following format.

GET /API/Contacts/username HTTP/1.1 
HOST: $baseuri:port 
Accept: text/xml 
Authorization: Basic ZmF0aWdhYmxlIGdlbmVyYXR=

And also I am calling the web service though HTTPS protocol.
The folowing is the code I am using :

HttpGet get = new HttpGet("https://secure.myapp.com/MyApp/API/Contacts/myname");

  get.addHeader("Accept","text/xml");
  get.addHeader("Authorization","Basic ZmF0aWdhYmxlIGdlbmVyYXR=");          
  get.addHeader("Host","https://secure.myapp.com");
  get.addHeader("Connection Use","HTTP 1.1");

  DefaultHttpClient client =  new DefaultHttpClient();
  ResponseHandler objHandler = new BasicResponseHandler();
  String getResponse = client.execute(get,objHandler);

But I am getting an Error : 400 Bad request.

I am not sure whether my code is correct. Is it necessary to specify the method (GET, POST or PUT) explicitly in the header?

Please help me...
Thnking You....

难道你不应该把 'Basic ZmF0aWdhYmxlIGdlbmVyYXR=' 用双引号括起来吗？
另请检查 Web 服务示例请求和响应，并确保指定了所有内容。

哦...
那是我的错误。
我没有保留添加标题的顺序。
当我根据请求更改其订单时，它工作正常。

在请求中，HOST 应该是第一个参数。
以下是更正后的代码。

get.addHeader("Host","secure.myapp.com");
get.addHeader("Accept","text/xml");   
get.addHeader("Authorization","Basic ZmF0aWdhYmxlIGdlbmVyYXR=");                
get.addHeader("Connection Use","HTTP 1.1");

抱歉打扰大家了...

Ohh...
That was my mistake.
I did not keep the order of adding headers.
When I changed its order according to the Request it is working fine.

In the request the HOST should be the first parameter.
The following is the corrected code.

get.addHeader("Host","secure.myapp.com");
get.addHeader("Accept","text/xml");   
get.addHeader("Authorization","Basic ZmF0aWdhYmxlIGdlbmVyYXR=");                
get.addHeader("Connection Use","HTTP 1.1");

Sorry to disturb you all...
