 3.接口默认的字符编码是UTF-8，接口需要实现对req_enc和resp_enc参数的支持。在JSP的最顶部，实现类似下面的代码：
-
-        String queryString = request.getQueryString();
-        String requestEncoding = getParam(queryString,"req_enc");
-        String responseEncoding = getParam(queryString,"resp_enc");
-        if(isNotBlank(requestEncoding)){
-            request.setCharacterEncoding(requestEncoding);
+注意：需要用getQueryString()，不能用getParameter()
+String queryString = request.getQueryString();
+String reqEnc = getQueryValue(queryString,"req_enc=");
+if(reqEnc!=null){
+    request.setCharacterEncoding(reqEnc);
+}
+String respEnc = getQueryValue(queryString,"resp_enc=");
+if(respEnc!=null){
+    //out.println(respEnc);
+    response.setCharacterEncoding(respEnc);
+}
+String getQueryValue(String queryString,String key){
+    if(queryString==null || queryString.length()==0)return null;
+    int reqIdx = queryString.indexOf(key);//req_enc=utf-8&resp_enc=gbk
+    if(reqIdx!=-1){
+        reqIdx = reqIdx+key.length();
+        int endIdx = reqIdx;
+        for (; 
+        endIdx < queryString.length() && queryString.charAt(endIdx)!='&'; 
+        endIdx++) {
         }
-        if(isNotBlank(responseEncoding)){
-            response.setCharacterEncoding(responseEncoding);
+        if(endIdx>reqIdx){
+            return queryString.substring(reqIdx,endIdx);
         }
+    }
+    return null;
+}
 
 4.所有有写操作的数据接口，必须用POST方式提交，在接口里需要判断提交方式，拒绝GET的调用请求。
