问题描述
我正在尝试使用 volley String 请求从服务器获取访问令牌.我也尝试过制作 JsonObjectRequest .两者都在下面.
I'm trying to get access tokens from the server using a volley String request. I have tried making a JsonObjectRequest also. Both are below.
public void getAuthenticationTokens(Object param1, final CustomListener<String> listener)
{
//String url = prefixURL + "this/request/suffix";
String url = "https://lw.xxx.co.uk/connect/token";
StringRequest request = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>()
{
@Override
public void onResponse(String response) {
// response
Log.e("Response", response);
}
},
new Response.ErrorListener()
{
@Override
public void onErrorResponse(VolleyError error) {
// error
Log.e("Error.Response", error.networkResponse.toString());
}
}
) {
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String,String> params = new HashMap<>();
params.put("Content-Type","application/x-www-form-urlencoded");
//..add other headers
return params;
}
@Override
protected Map<String, String> getParams()
{
Map<String, String> params = new HashMap<String, String> ();
params.put("scope", "openid email phone profile offline_access roles");
params.put("resource", "window.location.origin");
params.put("grant_type", "password");
params.put("username", "support@xxx.com");
params.put("password", "tempPxxx");
return params;
}
};
requestQueue.add(request);
.
public void getAuthenticationTokens(Object param1, final CustomListener<String> listener)
{
//String url = prefixURL + "this/request/suffix";
String url = "https://lw.xxx.co.uk/connect/token";
Map<String, Object> jsonParams = new HashMap<>();
jsonParams.put("scope", "openid email phone profile offline_access roles");
jsonParams.put("resource", "window.location.origin");
jsonParams.put("grant_type", "password");
jsonParams.put("username", "support@xxx.com");
jsonParams.put("password", "tempPxxx");
JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, url, new JSONObject(jsonParams),
new Response.Listener<JSONObject>()
{
@Override
public void onResponse(JSONObject response)
{
Log.d(TAG + ": ", "somePostRequest Response : " + response.toString());
if(null != response.toString())
listener.getResult(response);
}
},
new Response.ErrorListener()
{
@Override
public void onErrorResponse(VolleyError error)
{
if (null != error.networkResponse)
{
Log.e(TAG + ": ", "Error Response code: " + error.networkResponse.statusCode);
listener.getResult(null);
}
}
}){
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
// Map<String,String> params = super.getHeaders();
// if(params==null)params = new HashMap<>();
Map<String,String> params = new HashMap<>();
params.put("Content-Type","application/x-www-form-urlencoded");
//..add other headers
return params;
}
};
requestQueue.add(request);
.
我从服务器收到以下响应:
I get the following response from the server:
E/Volley: [31388] BasicNetwork.performRequest: Unexpected response code 400 for https://lw.xxx.co.uk/connect/token
.
我编写服务器端代码的同事询问了如何将以下 Angular 代码(他使用 API 的代码)转换为 Android.
My colleague who has written the server-side code has asked how to convert the following Angular code (his code that works with the API), to Android.
有人可以帮忙吗?
getLoginEndpoint(userName: string, password: string): Observable<Response> {
let header = new Headers();
header.append("Content-Type", "application/x-www-form-urlencoded");
let searchParams = new URLSearchParams();
searchParams.append('username', userName);
searchParams.append('password', password);
searchParams.append('grant_type', 'password');
searchParams.append('scope', 'openid email phone profile offline_access roles');
searchParams.append('resource', window.location.origin);
let requestBody = searchParams.toString();
return this.http.post(this.loginUrl, requestBody, { headers: header });
}
推荐答案
问题出在几个方面.
我将 "params.put("resource", "window.location.origin"); " 替换为 "params.put("resource", "https://lw.xxx.co.uk");"
I replaced "params.put("resource", "window.location.origin"); " with "params.put("resource", "https://lw.xxx.co.uk");"
此外，我发现 Volley 忽略了 getHeaders 覆盖，因此我将该方法注释掉并使用以下内容设置标题.
Also, I found out that Volley ignore the getHeaders override, so I commented that method out and used the following to set the headers.
@Override
public String getBodyContentType() {
return "application/x-www-form-urlencoded";
}
public void getAuthenticationTokens(Object param1, final String userName, final String password, final CustomListener<JSONObject> listener)
{
String url = "https://lw.xxx.co.uk/connect/token";
StringRequest request = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>()
{
@Override
public void onResponse(String response) {
// response
Log.e("Response", response);
}
},
new Response.ErrorListener()
{
@Override
public void onErrorResponse(VolleyError error) {
// error
Log.e("Error.Response", error.networkResponse.toString());
}
}
) {
/* @Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String,String> params = new HashMap<>();
params.put("Content-Type","application/x-www-form-urlencoded");
//..add other headers
return params;
}*/
@Override
public String getBodyContentType() {
return "application/x-www-form-urlencoded";
}
@Override
protected Map<String, String> getParams()
{
Map<String, String> params = new HashMap<String, String> ();
params.put("scope", "openid email phone profile offline_access roles");
params.put("resource", "https://lw.xxx.co.uk");
params.put("grant_type", "password");
params.put("username", userName);
params.put("password", password);
return params;
}
@Override
protected VolleyError parseNetworkError(VolleyError response) {
try {
String json = new String(response.networkResponse.data, HttpHeaderParser.parseCharset(response.networkResponse.headers));
Log.e(TAG, "reponse error = " + json);
}catch (Exception e){}
return super.parseNetworkError(response);
}
};
requestQueue.add(request);
}//end of getAuthenticationTokens
