 5、httpclient中文乱码解决

Java代码

1. httpclient默认使用ISO-8859-1读取http响应的内容，如果内容中包含汉字的话就得动用丑陋的new String(str.getBytes("ISO-8859-1"),"GBK");语句了。    
2.   
3. 解决办法就是使用以下配置。   
4.   
5. private static final String CONTENT_CHARSET = "GBK";// httpclient读取内容时使用的字符集   
6.   
7. HttpClient client = new HttpClient();   
8. client.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, CONTENT_CHARSET);  

httpclient默认使用ISO-8859-1读取http响应的内容，如果内容中包含汉字的话就得动用丑陋的new String(str.getBytes("ISO-8859-1"),"GBK");语句了。 

解决办法就是使用以下配置。

private static final String CONTENT_CHARSET = "GBK";// httpclient读取内容时使用的字符集

HttpClient client = new HttpClient();
client.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, CONTENT_CHARSET);

httpclient GetMethod 传参数 支持中文

 

    private static HttpMethod getGetMethod()throws Exception{
     String propertyValue1 = "北京";
     String propertyValue2= "大厦";
     String parameterValue1 = URLEncoder.encode(propertyValue1,"gbk");
     String parameterValue2 = URLEncoder.encode(propertyValue2,"gbk");
    
       return new GetMethod("/jquery/index.action?username="+parameterValue1+"&password="+parameterValue2);
    }

在
    String result = new String(method.getResponseBodyAsString().getBytes("iso-8859-1"));
     System.out.println(result);   

这样一处理 就解决了问题，研究了半天才搞定，很简单的。
