解决post请求接收数据类型为text/html时参数传递的问题

正确操作如下

DefaultHttpClient httpClient = new DefaultHttpClient();
String queryString=MapUtils.map2QueryString(params).substring(1);//分割成一对对kv
HttpPost method = new HttpPost(url);
StringEntity entity = new StringEntity(queryString,"utf-8");
entity.setContentEncoding("UTF-8");
entity.setContentType("application/x-www-form-urlencoded" );//这边注意不是设置成x-www-form-urlencoded
method.setEntity(entity);//
try {
HttpResponse result = httpClient.execute(method);
JSONObject jsonResult = null;
String str = "";

Header[] headers = result.getAllHeaders();
for (Header header : headers)
{
System.out.println(header.toString());
}
/** 读取服务器返回过来的json字符串数据 **/

str = EntityUtils.toString(result.getEntity());
/** 把json字符串转换成json对象 **/
jsonResult = JSONObject.fromObject(str);
System.out.println(jsonResult);
} catch (Exception
4000
e) {
System.out.println("post请求提交失败:" + url);
}
