Kotlin中如何使用OkHttp设置连接超时与套接字超时？

Hey there! I totally get where you're coming from—OkHttp uses an immutable design, which means you can't tweak timeouts directly on an already-built OkHttpClient instance (that's why you only see getter methods like connectTimeoutMillis()). Instead, you need to use the Builder pattern to configure these settings before creating the client.

Here's a straightforward Kotlin example to set both connection and socket (read) timeouts:

import okhttp3.OkHttpClient
import java.util.concurrent.TimeUnit

// Configure timeouts using OkHttpClient.Builder
val client = OkHttpClient.Builder()
    // Set connection timeout (time to establish a connection to the server)
    .connectTimeout(30, TimeUnit.SECONDS)
    // Set read timeout (time to wait for data after connection is established)
    .readTimeout(60, TimeUnit.SECONDS)
    // Optional: Set write timeout (time to wait for sending data)
    .writeTimeout(60, TimeUnit.SECONDS)
    // Build the final immutable OkHttpClient instance
    .build()

Key Notes: #

• OkHttpClient instances are immutable once built, so all configuration (including timeouts) must happen during the builder phase.
• If you already have an existing OkHttpClient and want to adjust timeouts without reconfiguring everything else, use newBuilder() to inherit the original client's settings:

  // Modify timeouts based on an existing client
  val updatedClient = client.newBuilder()
      .connectTimeout(45, TimeUnit.SECONDS)
      .readTimeout(90, TimeUnit.SECONDS)
      .build()
  

• After building the client, you can still use methods like client.connectTimeoutMillis() to retrieve the configured timeout values, just like you were doing before.
