[Android] Thread download resources ensure that resources are in place and adopt OkHttp’s three-party network download & file caching strategy

Background The third-party URL playback method using SVGA will be slower, and the SVGA effect will appear after a delay of at least 3 seconds. Therefore, the strategy is changed: download all online SVGA to local playback, then network caching will be used to achieve the effect. Implementation Then you have to achieve the following […]

Android development framework series OkHttp file download function implementation (including breakpoint resume download)

If you don’t know much about okhttp, you can refer to my other blog Code part package; import android.util.Log; import org.json.JSONObject; import; import; import; import; import; import java.nio.MappedByteBuffer; import java.nio.channels.FileChannel; import okhttp3.Call; import okhttp3.Callback; import okhttp3.FormBody; […]

Asynchronously calling RESTful interface based on okhttp3 and CompletableFuture

Application scenarios When the server program provides a set of RESTful interfaces for third-party calls, it often needs to provide the other party with an SDK. At this time, if you simply use the okhttp3 client to encapsulate the calls, when the request volume is large, request blocking will often occur and the JVM memory […]

Self-developed a simple version of OkHTTP

One, background In order to thoroughly understand the principle of okhttp, I developed one based on okhttp. Second, ideas If the business does not issue a request, it is packaged with AsyncCall, and then under the action of the network distributor, each specific Call is executed. These specific Calls will pass through layers of interceptors […]

[Java]_[Intermediate]_[Use okhttp3 and HttpClient proxy to access external networks]

Scene Commonly used Java http libraries include HttpClient and Okhttp3. If the company restricts network access, a proxy is required. How to use proxy Proxy when accessing external network? <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.5.13</version> </dependency> <dependency> <groupId>com.squareup.okhttp3</groupId> <artifactId>okhttp</artifactId> <version>3.14.9</version> </dependency> Description In terms of performance, Okhttp3 is better. Because access to both libraries is running from […]

An article on understanding the OkHttp source code implementation principle — a brief description

This article is reproduced from the blog of programmer Jiang. The article mainly shares his exploration and analysis of the principles of OkHttp. I believe it will be helpful to everyone! Knowledge sharer. OkHttp can be said to be the most common network request framework in Android development. OkHttp is easy to use, highly scalable, […]

Reading OkHttp source code in Android 2 (chain of responsibility model)

The blogger discovered a giant artificial intelligence learning website a few days ago. It is easy to understand and humorous. I can’t help but share it with everyone. Click to jump to the tutorial Android OkHttp source code reading detailed explanation 1 Looking at the OkHttp source code, I found that OkHttp uses the responsibility […]

OkHttp usage and analysis in Kotlin

build.gradle dependencies { //OkHttp implementation ‘com.squareup.okhttp3:okhttp:4.9.0’ } Simple usage example val okHttpClient = OkHttpClient.Builder() .connectTimeout(Duration.ofSeconds(10)) .readTimeout(Duration.ofSeconds(10)) .writeTimeout(Duration.ofSeconds(10)) .retryOnConnectionFailure(true) .build() val request = Request.Builder().url(url).build() val call = okHttpClient.newCall(request) call.enqueue(object : Callback { override fun onFailure(call: Call, e: IOException) { Log.e(“TAG”, “onFailure:${e.message}”) } override fun onResponse(call: Call, response: Response) { Log.d(“TAG”, “onResponse: ${response.body?.string()}”) } }) 1. Obtain […]

Spring boot integrates Okhttp3 and encapsulates request tools

1. Why use okHttp OkHttp is an efficient, flexible and easy-to-use HTTP client library with the following advantages: Higher performance: OkHttp adopts an asynchronous model in network request processing, and applies various technologies such as connection pooling, compression, and network protocols to it, thereby improving the efficiency and processing speed of network requests. More powerful […]
