这些参数可以假设传递给php servier上名为LoadClassTimetable的函数。 I am trying to get the response(some values) from this funciton.
我试图从这个函数得到响应(一些值)。 However, the server returns me error 400.
但是,服务器返回错误400。
This is the server I am trying to connect 这是我尝试连接的服务器
URL url = new URL(" http://appsvtmp.test.com "); URL url =新网址(“ http://appsvtmp.test.com ”);
These are the parameters I try to send 这些是我尝试发送的参数
Map<String,Object> requestPayload = new LinkedHashMap<>();
requestPayload.put("end_day", "2016-12-31 23:59:59+11:00");
requestPayload.put("start_day", "2016-12-11 00:00:00+11:00");
requestPayload.put("type", 1);

These are the headers I try to add. 这些是我尝试添加的标题。
conn.setRequestMethod("POST");
conn.setRequestProperty("x-amz-target", "SchoolLearnMeter_19801212.LoadClassTimetable");
conn.setRequestProperty("x-amz-content-sha256", "bbace604ca933f1f7726e1f6ec9af2cc32e8b4dcd13285bd079a465d6e2790ed");
conn.setRequestProperty("User-Agent", USER_AGENT);
conn.setRequestProperty("Accept-Language", "en-US,en;q=0.8");
conn.setRequestProperty("Content-Type", "application/json;charset=UTF-8");
conn.setRequestProperty("Content-Length", String.valueOf(dataEntryBytes.length));
Are there anything wrong? 有什么不对吗? Or I am completely wrong?
或者我完全错了?
Error code 400 means that the request was malformed. 错误代码400表示请求格式错误。 In other words, the data stream sent by the client to the server didn't follow the rules.
换句话说,客户端发送到服务器的数据流不遵循规则。
Generally Error Code 400 is thrown by validators, so, please check your data. 通常验证器会抛出错误代码400,因此,请检查您的数据。 Following should be done in such scenario.
应该在这种情况下进行以下操作。
