问题描述
我正在尝试从我的android应用程序连接到django服务器.我正在尝试访问我的api，并用volly发出POST请求.一切都准备好了.需要所有参数和标头，但仍然出现此错误.
I am trying to connect to a django server from my android application. I am trying to access my api, making a POST request with volly. Everything is set. All the params and headers required, but still I get this error.
log: [490] BasicNetwork.performRequest: Unexpected response code 401 for https://example.com/
这不是让我访问我的django Api.它在PHP服务器上正常工作.
It's not letting me access my django Api. It works fine with the PHP server.
public void vollyRequest()
{
RequestQueue queue = Volley.newRequestQueue(this);
StringRequest request = new StringRequest(Request.Method.POST , "https://example.com/", new Response.Listener<String>() {
@Override
public void onResponse(String response) {
Toast.makeText(MainActivity.this, "RESPONSE: " + response, Toast.LENGTH_SHORT ).show();
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(MainActivity.this, "ERROR: " + error, Toast.LENGTH_SHORT ).show();
}
}) {
@Override
protected Map<String,String> getParams(){
Map<String,String> params = new HashMap<String, String>();
params.put("username","***");
params.put("password","***");
return params;
}
// @Override
// public Map<String, String> getHeaders() throws AuthFailureError {
// Map<String,String> params = new HashMap<String, String>();
// params.put("Content-Type","application/x-www-form-urlencoded");
// return params;
// }
};
queue.add(request);
}
推荐答案
我自己解决了...此代码将为您提供一个身份验证令牌，并提供您提供的用户名和密码，然后将该令牌放入标头中以从服务器获取数据...
i solved it my self...This code will get you an auth-token, with the username and password you provide, and then that token will be put in the header to get data from the server...
public void vollyRequestGetAuthToken()
{
RequestQueue queue = Volley.newRequestQueue(this);
StringRequest request = new StringRequest(Request.Method.POST , "https://example.com/get-auth-token/", new Response.Listener<String>() {
@Override
public void onResponse(String response) {
Toast.makeText(MainActivity.this, "RESPONSE: " + response, Toast.LENGTH_SHORT ).show();
System.out.println("RESPONSE: >>> " + response + "<<<");
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(MainActivity.this, "ERROR: " + error, Toast.LENGTH_SHORT ).show();
}
}) {
@Override
protected Map<String,String> getParams(){
Map<String,String> params = new HashMap<String, String>();
params.put("username","*****");
params.put("password","*****");
return params;
}
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String,String> params = new HashMap<String, String>();
params.put("Authorization",
String.format("Basic %s", Base64.encodeToString(
String.format("%s:%s", "<username>", "<password>").getBytes(), Base64.DEFAULT)));
params.put("username" , "*****" );
params.put("password" , "*****" );
return params;
}
};
queue.add(request);
}
现在，当您拥有身份验证令牌时，请使用以下代码发送身份验证令牌以获取数据
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Authorization", "Token <token>");
return headers;
}
