我使用OkHttp 2.3
进行基本身份验证请求,根据OKHttp文档,它会自动重试未经身份验证的请求,但每当我提供无效凭据时,请求都会花费太多时间,我会在端:
java.net.ProtocolException:后续请求太多:21
如何阻止OkHttp自动重试未经身份验证的请求,并返回401 Unauthorized
?
答案 0 :(得分:13)
protected Authenticator getBasicAuth(final String username, final String password) {
return new Authenticator() {
private int mCounter = 0;
@Override
public Request authenticate(Proxy proxy, Response response) throws IOException {
if (mCounter++ > 0) {
throw new AuthenticationException(
AuthenticationException.Type.INVALID_LOGIN, response.message());
}
String credential = Credentials.basic(username, password);
return response.request().newBuilder().header("Authorization", credential).build();
}
@Override
public Request authenticateProxy(Proxy proxy, Response response) throws IOException {
return null;
}
};
}
在我的身份验证器中,我只计算尝试次数 - 在X次尝试之后,我抛出异常。

Traxdata的修改版本的答案有效:
protected Authenticator getBasicAuth(final String username, final String password) {
return new Authenticator() {
private int mCounter = 0;
@Override
public Request authenticate(Route route, Response response) throws IOException {
Log.d("OkHttp", "authenticate(Route route, Response response) | mCounter = " + mCounter);
if (mCounter++ > 0) {
Log.d("OkHttp", "authenticate(Route route, Response response) | I'll return null");
return null;
} else {
Log.d("OkHttp", "authenticate(Route route, Response response) | This is first time, I'll try to authenticate");
String credential = Credentials.basic(username, password);
return response.request().newBuilder().header("Authorization", credential).build();
}
}
};
}
然后你需要:
OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.authenticator(getBasicAuth("username", "pass"));
retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.client(builder.build())
.addConverterFactory(GsonConverterFactory.create())
.build();
那就是它。
