HttpClient模拟客户端向 服务器接口 传递 Json 数据

HttpClient向服务器接口 传递 json参数，参数要做特殊的处理，否则报错。

错误原因是：HttpGet或 HttpPost都不能传包含 " 、“{"、"}"这样的参数，需要对特殊字符进行转义，把 " 转成%22，把 { 转成%7b，把 } 转成%7d

干脆直接自己 replaceAll 算了，两次：
“{” => %7B

“}” => %7D

对了，URLEncode从？之后的参数开始，不要把域名和路径也放进去了。

String x = IOUtility.read2String("d:/pushlog.txt");
x = URLEncoder.encode(x,"UTF-8");
x = x.replace(" ", "").replace("\"", "%22");
x = x.replace("{", "%B").replace("}", "%7D");
		
String uri = "http://10.131.80.148:8080/receive/log?data=" + x;  
HttpGet get = new HttpGet(uri);
System.out.println(get);
HttpResponse res = client.execute(get);;

 RequestVo reqVo = new RequestVo();
 reqVo.context = getApplicationContext();

 StringBuffer sb = new StringBuffer();
 sb.append("?info={\"type\":\"1\",");
 sb.append("\"shopid\":\"" + shopId + "\",");
 sb.append("\"fields\":{\"name\":true,");
 sb.append("\"address\":true,");
 sb.append("\"tel\":true,");
 sb.append("\"scores\":true,");
 sb.append("\"intro\":true}}");

 String param = sb.toString().replace("\"", "%22")
         .replace("{", "%7b").replace("}", "%7d");   //特殊字符进行转义
 reqVo.requestUrl = getString(R.string.detail_api).concat(param);
 reqVo.jsonParser = new ShopParser();

 BaseTask task = new BaseTask(getApplicationContext(), reqVo,
         handler);

 ThreadPoolManager.getInstance().addTask(task);

注意：参数里面如果有 空格的话，也需要转义，否则会有问题。
