Volley JsonObjectRequest发布请求忽略参数 [英] Volley JsonObjectRequest Post request ignoring params
问题描述
我正在尝试使用凌空连接到API，我正在设置所有参数和标题，但似乎这些参数被忽略了，我在这里缺少什么？上周我开始学习android排球，我有点迷失。
I'm trying to connect to an API using volley, I'm setting all the parameters and headers, but it seems that the params are being ignored, what am I missing here? I started learning android volley last week and I'm kind of lost.

推荐答案
很明显，有时我们需要在点击网址时提交请求参数。为此，我们必须覆盖 getParams（）方法，该方法应返回以键值格式发送的参数列表。
It is obvious that sometimes we need to submit request parameters while hitting the url. To do that we have to override getParams() method which should return list of parameters to be send in a key value format.
所以，在 JsonObjectRequest 中覆盖 getParams（）为
@Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("email", "rm@test.com.br");
params.put("senha", "aaa");
return params;
}
即。使用下面的代码作为
i.e. use below code as
JsonObjectRequest jsObjRequest = new JsonObjectRequest(Request.Method.POST,url,null,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
System.out.println(response);
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
})
{
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("TOKEN", "99KI9Gj68CgCf70deM22Ka64chef2C40Gm2lFJ2J0G9JkDaaDAcbFfd19MfacGf3FFm8CM1hG0eDiIk8");
return headers;
}
@Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("email", "rm@test.com.br");
params.put("senha", "aaa");
return params;
}
};

编辑：
401 是未授权的状态代码。如果您在尝试HTACCESS时遇到 401 ，请参阅问题。您需要使用 Authenticator 传递参数。
401 is the status code for "unauthorized". If you are getting a 401 while trying an HTACCESS see this question. You need to pass the parameters using an Authenticator.
