java Android和CherryPy

3 月，4 周 Questions & Answers 187

我正在开发一个Android应用程序，其中我必须在用cherrypy构建的RESTAPI上发出POST HTTP请求

以下是应用程序的java代码：

public String post(String host,int port,String path,String msg) throws IOException{
    URL url = new URL ("http",host,port,path);
    Log.e("track","sto per connettermi");
    URLConnection conn = url.openConnection();
    Log.e("track","connesso");
    conn.setDoOutput(true);
    conn.setDoInput(true);
    conn.setAllowUserInteraction(true);
    conn.getOutputStream().write(msg.getBytes());
    conn.getOutputStream().close();
    StringBuilder sb = new StringBuilder();
    BufferedReader in = new BufferedReader(
            new InputStreamReader(
                    conn.getInputStream()
            )
    );
    String line;
    while ((line = in.readLine()) != null)
        sb.append(line);
    in.close();
    return sb.toString();
}

这是REST API的python代码：

def POST(self,*uri,**params):
    if uri[0] == 'userAuth':
        tempJson = json.loads(cherrypy.request.body.read())
        user_name = tempJson['user_name']
        pwd = tempJson['pwd']
        if user_name in self.users:
            return json.dumps({"user_id":str(self.users.index(user_name)),"result":True})
        return json.dumps({"result":"Wrong Credentials","success":False})

在cherrypy服务器上，我收到以下错误： ValueError: No JSON object could be decoded 问题是，我通过java流发送数据，但无法用python对其进行解码。有没有一种方法可以将数据直接作为字符串发送，或者用python对其进行解码

已解决 修正了添加行的问题： conn.setRequestProperty("Content-Type","application/json");

@cherrypy.tools.json_in() @cherrypy.tools.json_out() def POST(self,*uri,**params): req = cherrypy.request if uri[0] == 'userAuth': user_name = req.json['user_name'] pwd = req.json['pwd'] if user_name in self.users: return {"user_id": str(self.users.index(user_name)), "result": True} return {"result": "Wrong Credentials","success": False}
