Retrofit2 将令牌放入带有占位符的 URL 中 [英] Retrofit2 put token in URL with placeholder

问题描述

我在用 auth-token 替换 url 中的占位符时遇到问题.

I have a Problem with replace the placeholder in the url with the auth-token.

我的 OkHttpClient:

My OkHttpClient:

OkHttpClient clientToken = new OkHttpClient.Builder()
            .addInterceptor(tokenInterceptor)
            .addInterceptor(interceptor)
            .connectTimeout(100, TimeUnit.SECONDS)
            .readTimeout(100, TimeUnit.SECONDS)
            .build();

我的令牌检查员:

private class TokenInterceptor implements Interceptor{

    @Override
    public Response intercept(Chain chain) throws IOException {
        Response mainResponse = chain.proceed(chain.request());
        //Auth Data available?
        if(RestClient.this.isAuthenticationDataSet()){
            //Get Token
            String currentToken = getToken(RestClient.this.authCustomerNumber,
                    RestClient.this.authUser,
                    RestClient.this.authPassword,
                    RestClient.this.authDeviceId);

            //Original RequestData
            Request originalRequest = chain.request();
            HttpUrl originalUrl = originalRequest.url();
            List<String> urlSegments = originalUrl.pathSegments();

            //New URL
            boolean tokenFoundInSegments = false;
            HttpUrl.Builder newUrlBuilder = originalUrl.newBuilder();

            //Search token placeholders in url segments
            for(int i=0; i<urlSegments.size(); i++){
                String segment = urlSegments.get(i);

                if(segment.equals(tokenPlaceholder)){
                    segment = currentToken;
                    tokenFoundInSegments = true;
                }

                newUrlBuilder.setPathSegment(i, segment);
            }

            //If not found in segments: Set token as get param
            if(!tokenFoundInSegments){
                newUrlBuilder.addQueryParameter("token", currentToken);
            }

            HttpUrl url = newUrlBuilder.build();
            Request tokenRequest = originalRequest.newBuilder().url(url).build();

            return chain.proceed(tokenRequest);
        }else{
            //No auth data available
            return chain.proceed(chain.request());
        }
    }
}

我的电话:

ObservableField<UserLoginData> userdata = 
UserBackend.getInstance(context).getUserLoginData();
//order the basket
Call<RestResult<BasketResult>> call = 
this.restAPIBasket.orderBasket(basket.getId(), userdata.get().getPassword());

call.enqueue(new Callback<RestResult<BasketResult>>() {
.....

网址:URL/R_token/password?format=json

URL: URL/R_token/password?format=json

我的问题:

当我调试时，改造会在不设置令牌的情况下执行调用，然后它会通过 tokenInterceptor 类并再次进行调用.谁能帮我解决这个问题?我不能总是将令牌用作查询，而只能在某些 URL 中用作路径

when I debug, retrofit executes a call without setting the token and then does it go through the tokenInterceptor class and make the call again. Can anyone help me to fix this Problem? I can not always use the token as a query but in certain URLs only as a path

推荐答案

问题是:Response mainResponse = chain.proceed(chain.request());

chain.proceed() 调用时不设置令牌，返回时设置令牌.也叫了两次.我删除了第一个，它的工作正常

chain.proceed() make the call witheout set the token and the return with set the token. also calls twice. I removed the first and it's work correct
