Android截击向服务器发布空请求，状态为200

Question

花了很多不眠之夜试图成功地将这些数据发布到我的服务器，但它返回了一个错误，它在poster中运行良好，问题是它向服务器发送了一个空请求。链接到服务器脚本。伙计们请帮我解决这个错误。这是邮递员请求和响应的屏幕截图。

下面是服务器端的控制台跟踪：

进一步编辑以显示我的服务器端代码：

控制器

@PostMapping(path = ENDPOINT_MOBILE_OTP)
public AuthenticationVO signInWithOTP(@Valid @RequestBody AuthenticationVO authenticationVO){
System.out.println("login request is:-"+authenticationVO.toString());
try {
if (authenticationVO != null) {
MultitenantUtility.request = httpRequest;
String tenantId = multitenantUtility.resolveCurrentTenantIdentifier();
if (tenantId != null) {
multitenantUtility.setCurrentTenant(tenantId);
authenticationVO = userService.checkLoginCredentialsWithOTP(authenticationVO);
} else {
System.out.println("request body is empty");
//throw new DMPBadRequestException("Request body is empty");
}
}
}
catch(Exception e)
{
System.out.println("Excepton "+e);
}
finally
{
multitenantUtility.clearThreadLocal();
LOGGER.info("authenticateUser - before returning");
}

return authenticationVO;
}

Answer 1

尝试发送JsonObjectRequest而不是StringRequest。按照这个答案

JsonObjectRequest request_json = new JsonObjectRequest(Request.Method.POST,url,object,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
Log.i("info", response.toString());
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
VolleyLog.e("Error: ", error.getMessage());
}
});

Answer 2

我已经解决了我的问题，只是在头中添加了主机，整个问题解决了，因此将数据保存在了我的数据库中。

@Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json; charset=utf-8");
headers.put("Host", "localhost:8080");

return headers;
}

特别感谢@ATIK_FAYSAL的友好努力。
