我正在使用Retrofit 2
在 Android 应用程序中发出 http 请求。我与之交谈的服务器需要OAuth 1.0
授权。我使用okhttp-signpost
from here 来处理 OAuth 签名。
这是我build.gradle
的 for 库包括:
compile 'com.squareup.retrofit2:retrofit:2.3.0'
compile 'se.akerfeldt:okhttp-signpost:1.1.0'
compile 'com.squareup.okhttp3:okhttp:3.0.0-RC1'
compile 'oauth.signpost:signpost-core:1.2.1.2'
在MyApi
课堂上,我定义dailyChart
为Retrofit GET request
:
import retrofit2.Call;
import retrofit2.http.GET;
import retrofit2.http.Query;
@GET("chart")
Call<ChartResponse> dailyChart(@Query("symbol") String symbol);
这是我的制作方法dailyChart() GET request
:
import se.akerfeldt.okhttp.signpost.OkHttpOAuthConsumer;
import se.akerfeldt.okhttp.signpost.SigningInterceptor;
// for OAuth signing
OkHttpOAuthConsumer consumer = new OkHttpOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(new SigningInterceptor(consumer))
.build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(.....)
.addConverterFactory(GsonConverterFactory.create())
.client(client)
.build();
MyApi myApi = retrofit.create(MyApi.class);
String symbol = '^KKKL';
Call<ChartResponse> call = myApi.dailyChart(symbol);
但是由于我作为参数传递给改造的^
字符,我得到了以下错误:^KKKL
@Query
D/OkHttp: --> GET https://......chart?symbol=^KKKL http/1.1
D/OkHttp: --> END GET
D/OkHttp: <-- HTTP FAILED: java.io.IOException: Could not sign request

所以我尝试url-encode
了symbol
, 在传递给 Retrofit 之前:
String symbol = '^KKKL';
try {
query = java.net.URLEncoder.encode(symbol, "UTF-8");
} catch (UnsupportedEncodingException ex) {
throw new StockHistoryNotFoundException(null, ex);
}
Call<ChartResponse> call = myApi.dailyChart(symbol);
然后我得到了另一个错误,如下所示。@Query
我认为 Retrofit 再次对我传入的已编码参数进行编码。
D/OkHttp: <-- 404 Not Found https:.....chart?symbol=%255EKKKL
任何人都知道任何解决这个问题?
