我正在尝试使用Retrofit2，我想这样的Token添加CC_2：
Authorization: Bearer Token但是下面的code行不通：
public interface APIService {
@Headers({"Authorization", "Bearer "+ token})
@GET("api/Profiles/GetProfile?id={id}")
Call<UserProfile> getUser(@Path("id") String id);
}
我的服务器是asp.net webApi。请帮助我该怎么办？
您有两个选择 - 您可以将其添加为参数 -
@GET("api/Profiles/GetProfile?id={id}")
Call<UserProfile> getUser(@Path("id") String id, @Header("Authorization") String authHeader);
这可能有点烦人，因为您必须在每个呼叫上传递"Bearer" + token。如果您没有太多需要令牌的电话，这是合适的。
如果要将标题添加到所有请求中，则可以使用OKHTTP Interceptor-
OkHttpClient client = new OkHttpClient.Builder().addInterceptor(new Interceptor() {
@Override
public Response intercept(Chain chain) throws IOException {
Request newRequest = chain.request().newBuilder()
.addHeader("Authorization", "Bearer " + token)
.build();
return chain.proceed(newRequest);
}
}).build();
Retrofit retrofit = new Retrofit.Builder()
.client(client)
.baseUrl(/** your url **/)
.addConverterFactory(GsonConverterFactory.create())
.build();
如果要添加载体令牌作为标题，则可以执行这些类型的过程。
这是一种使用承载令牌
的方法在您的接口中
@Headers({ "Content-Type: application/json;charset=UTF-8"})
@GET("api/Profiles/GetProfile")
Call<UserProfile> getUser(@Query("id") String id, @Header("Authorization") String auth);
之后，您将以这种方式调用改装对象
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("your Base URL")
.addConverterFactory(GsonConverterFactory.create())
.build();
APIService client = retrofit.create(APIService.class);
Call<UserProfile> calltargetResponse = client.getUser("0034", "Bearer "+token);
calltargetResponse.enqueue(new Callback<UserProfile>() {
@Override
public void onResponse(Call<UserProfile> call, retrofit2.Response<UserProfile> response) {
UserProfile UserResponse = response.body();
Toast.makeText(this, " "+response.body(), Toast.LENGTH_SHORT).show();
}
@Override
public void onFailure(Call<UserProfile> call, Throwable t) {
//Toast.makeText(this, "Failed ", Toast.LENGTH_SHORT).show();
}
});
另一种方法是使用截距，这是上一个答案相似的。但是，那个时候您只需要修改界面。
@Headers({ "Content-Type: application/json;charset=UTF-8"})
@GET("api/Profiles/GetProfile")
Call<UserProfile> getUser(@Query("id") String id);
希望这对您有用。
基于@iagreen解决方案kotlin版本，具有@daniel Wilson建议的不同类别和结构
制作像这样的改造实例
object RetrofitClientInstance {
private var retrofit: Retrofit? = null
private val BASE_URL = "http://yoururl"
val retrofitInstance: Retrofit?
get() {
if (retrofit == null) {
var client = OkHttpClient.Builder()
.addInterceptor(ServiceInterceptor())
//.readTimeout(45,TimeUnit.SECONDS)
//.writeTimeout(45,TimeUnit.SECONDS)
.build()
retrofit = Retrofit.Builder()
.baseUrl(BASE_URL)
.client(client)
.addConverterFactory(GsonConverterFactory.create())
.build()
}
return retrofit
}
}
添加ServiceInterceptor类，如下
class ServiceInterceptor : Interceptor{
var token : String = "";
fun Token(token: String ) {
this.token = token;
}
override fun intercept(chain: Interceptor.Chain): Response {
var request = chain.request()
if(request.header("No-Authentication")==null){
//val token = getTokenFromSharedPreference();
//or use Token Function
if(!token.isNullOrEmpty())
{
val finalToken = "Bearer "+token
request = request.newBuilder()
.addHeader("Authorization",finalToken)
.build()
}
}
return chain.proceed(request)
}
}
登录接口和数据类实现
interface Login {
@POST("Login")
@Headers("No-Authentication: true")
fun login(@Body value: LoginModel): Call<LoginResponseModel>
@POST("refreshToken")
fun refreshToken(refreshToken: String):
Call<APIResponse<LoginResponseModel>>
}
data class LoginModel(val Email:String,val Password:String)
data class LoginResponseModel (val token:String,val
refreshToken:String)
在这样的任何活动中称呼此
val service = RetrofitClientInstance.retrofitInstance?.create(Login::class.java)
val refreshToken = "yourRefreshToken"
val call = service?.refreshToken(refreshToken)
call?.enqueue(object: Callback<LoginResponseModel>{
override fun onFailure(call: Call<LoginResponseModel>, t: Throwable) {
print("throw Message"+t.message)
Toast.makeText(applicationContext,"Error reading JSON",Toast.LENGTH_LONG).show()
}
override fun onResponse(call: Call<LoginResponseModel>, response: Response<LoginResponseModel>) {
val body = response?.body()
if(body!=null){
//do your work
}
}
})

这会将您的令牌添加到构建器中，您可以随时更改登录/注销时。
object ApiService {
var YOUR_TOKEN = ""
private var retrofit: Retrofit = Retrofit.Builder()
.baseUrl("YOUR_URL")
.addConverterFactory(GsonConverterFactory.create())
.client(OkHttpClient.Builder().addInterceptor { chain ->
val request = chain.request().newBuilder().addHeader("Authorization", "Bearer ${YOUR_TOKEN}").build()
chain.proceed(request)
}.build())
.build()
var service: AppAPI = retrofit.create(AppAPI::class.java)
private set
}
您需要将拦截器添加到OkHttpClient中。
添加一个名为OAuthInterceptor的类。
class OAuthInterceptor(private val tokenType: String, private val accessToken: String) : Interceptor {
override fun intercept(chain: Interceptor.Chain): okhttp3.Response {
var request = chain.request()
request = request.newBuilder().header("Authorization", "$tokenType $accessToken").build()
return chain.proceed(request)
}
}
之后，当您初始化RetrofitApiService接口时，您将需要此。
interface RetrofitApiService {
companion object {
private const val BASE_URL = "https://api.coursera.org/api/businesses.v1/"
fun create(accessToken: String): RetrofitApiService {
val client = OkHttpClient.Builder()
.addInterceptor(OAuthInterceptor("Bearer", accessToken))
.build()
val retrofit = Retrofit.Builder()
.addConverterFactory(GsonConverterFactory.create())
.baseUrl(BASE_URL)
.client(client)
.build()
return retrofit.create(RetrofitApiService::class.java)
}
}
}

最好的方法是使用新的身份验证器API。
class TokenAuthenticator : Authenticator {
override fun authenticate(route: Route?, response: Response): Request? {
if (response.request.header("Authorization") != null) {
return null
}
return response.request.newBuilder().header("Authorization", "Bearer " + token).build()
}
}
OkHttpClient.Builder().authenticator(TokenAuthenticator()).build()
