【中文标题】应用程序在 java.net.SocketTimeoutException 上崩溃：超时（Kotlin、Retrofit）【英文标题】：App crashes on java.net.SocketTimeoutException: timeout (Kotlin, Retrofit) 【发布时间】：2018-11-19 06:38:42 【问题描述】：如果没有响应，应用会在这条线上崩溃。
chain.proceed(requestBuilder.build())
这是我的 RetrofitClient 课程
class RetrofitClient
private val apiService: ApiServiceInterface
init
val builder = Retrofit.Builder()
builder.baseUrl(RequestParameters.BASE_URL)
builder.addConverterFactory(GsonConverterFactory.create())
builder.addCallAdapterFactory(RxJava2CallAdapterFactory.create())//added for adapter
builder.client(getClient())
val retrofit = builder.build()
apiService = retrofit.create(ApiServiceInterface::class.java)
companion object
private var clientInstance: RetrofitClient? = null
lateinit var context: Context
fun getInstance(): RetrofitClient
if (clientInstance == null)
clientInstance = RetrofitClient()
return clientInstance as RetrofitClient
fun getApiInterface(): ApiServiceInterface
return apiService
private fun getClient(): OkHttpClient
val httpClient = OkHttpClient.Builder()
httpClient.readTimeout(25, TimeUnit.SECONDS)
httpClient.connectTimeout(25, TimeUnit.SECONDS)
httpClient.addInterceptor chain ->
val original = chain.request()
val requestBuilder = original.newBuilder()
.header(RequestParameters.X_API, RequestParameters.H_XAPI_KEY)
.method(original.method(), original.body())
chain.proceed(requestBuilder.build())
// set your desired log level
val logging = HttpLoggingInterceptor()
logging.level = HttpLoggingInterceptor.Level.HEADERS
logging.level = HttpLoggingInterceptor.Level.BODY
httpClient.addInterceptor(logging)
return httpClient.build()
这是日志中的错误：

【问题讨论】：
你能解决这个问题吗？？ 如果您使用的是 Corouine + Kotlin，我最后通过 this 解决了这个问题 【参考方案1】：试试这个代码方式.. 制作改造对象创建部分。
class ApiClient
companion object
val BASE_URL = "https://simplifiedcoding.net/demos/"
var retrofit: Retrofit? = null
fun getClient(): Retrofit?
if (retrofit == null)
val interceptor = HttpLoggingInterceptor()
interceptor.level = HttpLoggingInterceptor.Level.BODY
val client = OkHttpClient.Builder().apply
readTimeout(20, TimeUnit.SECONDS)
writeTimeout(20, TimeUnit.SECONDS)
connectTimeout(20, TimeUnit.SECONDS)
addInterceptor(interceptor)
addInterceptor chain ->
var request = chain.request()
request = request.newBuilder()
.build()
val response = chain.proceed(request)
response
retrofit = Retrofit.Builder()
.baseUrl(BASE_URL)
.client(client.build())
.addConverterFactory(GsonConverterFactory.create())
.build()
return retrofit
为api调用制作接口..
interface ApiInterface
@GET("marvel")
fun getData(): Call<List<Hero>>
在像这样调用 api 的活动或片段中，我希望你创建响应 pojo 类
var apiInterface: ApiInterface = ApiClient.getClient()!!.create(ApiInterface::class.java)
var hero: Call<List<Hero>>
hero = apiInterface.getData()
hero.enqueue(object : Callback<List<Hero>>
override fun onFailure(call: Call<List<Hero>>?, t: Throwable?)
closeDialog(dialog)
Toast.makeText(mContext, t?.message, Toast.LENGTH_SHORT).show()
Log.d("Error:::",t?.message)
override fun onResponse(call: Call<List<Hero>>?, response: Response<List<Hero>>?)
mHeroDataList.clear()
if (response != null && response.isSuccessful && response.body() != null)
closeDialog(dialog)
mHeroDataList .addAll(response.body()!!)
setAdapter(mHeroDataList)
)
【讨论】：
这无济于事，因为它与我的代码相同。 增加超时值。 实际上，问题是应用程序崩溃，如果直到超时秒才响应。我们怎么能处理这个？我担心的是如果没有响应（无论是 30 秒还是 60 秒），应用程序不应该崩溃。增加超时值并不是一个理想的解决方案。【参考方案2】：当存在no network 时，此代码会引发异常。因此，您可以使用try and catch block 捕获异常。您可以将 try and catch 放在您调用网络的位置。而且它不会再次让您的应用崩溃。
