java调用sap中文乱码

背景：java中调用SAP接口，传参body，接口参数能传过去，但是SAP接收到的中文乱码，如图：

这里试了utf-8，GB2321，UTF-16LE,UTF-16BE等编码格式，SAP那边接收到的都是乱码，查遍了百度无果，方法几乎都一样，偶然看到一篇好几年前的帖子，破案了

原因：对方的SAP接口只支持接收繁体中文的编码格式UTF8，改成这个以后就好了

 

 

 代码如下：

test：

String url="";
String jsonStr = "";
String httpOrgCreateTestRtn = HttpClientUtil.doPost(url, jsonStr, "utf-8");
//返回的数据要用utf-8接收，传的时候用utf8

---------------------------------------------------------------------------------------------调用

public static String doPost(String url,String jsonstr,String charset){

    HttpClient httpClient = null;
    HttpPost httpPost = null;
    String result = null;
    try{
        httpClient = new SSLClient();
        httpPost = new HttpPost(url);
        httpPost.addHeader("content-type", "application/json;charset=UTF8");
        httpPost.addHeader("Accept", "*/*");
        httpPost.addHeader("Connection", "keep-alive");
        System.out.println("jsonstrhttpPostEntity="+jsonstr);
        StringEntity se=new StringEntity(jsonstr,"UTF8");
        se.setContentType("application/json;charset=UTF8");
        se.setContentEncoding(new BasicHeader("Content-Type", "application/json"));
        httpPost.setEntity(se);
        System.out.println("httpPost="+httpPost);
        System.out.println("httpPostEntitySE="+se);
        HttpResponse response = httpClient.execute(httpPost);
        if(response != null){
            HttpEntity resEntity = response.getEntity();
            if(resEntity != null){
                result = EntityUtils.toString(resEntity,charset);
            }
        }
    }catch(Exception ex){
        ex.printStackTrace();
    }
    return result;
}
