This article mainly explains "what is okhttp and okio in the analysis of Android web request framework". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Next let the editor to take you to learn "Android network request framework parsing what is okhttp and okio" it!

Android web request

Let's take a look at today's outline.

Import okhttp and okio dependencies

Disable the inspection of plaintext traffic requests

Add access permission

Layout and code implementation

Running result

Here are the concrete steps

Import okhttp and okio dependencies

1. Open File-Project Structure-Dependencies

two。 Select your own program file, click the plus sign, and select Library Dependency

3. Search for okhttp, select Com.squareup.okhttp3, and click the ok button, which may take a long time.

4.okio ditto

5. Apply, confirm

6. At this point we can see that Gradle Scripts-build.gradle (Module: My_Application.app) has two more dependencies.

Module: My_Application.app is its own corresponding app

II. Disable the inspection of plaintext traffic requests

1. Create a new xml folder under the res directory and a new nettools.xml under the xml folder

Nettools.xml

two。 Add the nettools.xml you just created to the manifests-AndroidManifest.xml

Android:networkSecurityConfig= "@ xml/nettools"

Third, add network request permissions

Add in manifests-AndroidManifest.xml

`

Fourth, code implementation 1. The realization of main code

MainActivity.java

Import androidx.annotation.UiThread;import androidx.appcompat.app.AppCompatActivity;import android.os.Bundle;import android.util.Log;import android.view.View;import android.widget.Button;import android.widget.TextView;import java.io.IOException;import okhttp3.OkHttpClient;import okhttp3.Request;import okhttp3.Response;public class MainActivity extends AppCompatActivity {private Button btn; private TextView txt; @ Override protected void onCreate (Bundle savedInstanceState) {super.onCreate (savedInstanceState); setContentView (R.layout.activity_main) InitView ();} private void initView () {btn = findViewById (R.id.btn); txt = findViewById (R.id.txt); btn.setOnClickListener (new View.OnClickListener () {@ Override public void onClick (View view) {request ();}}) } protected void request () {new Thread (new Runnable () {@ Override public void run () {OkHttpClient client = new OkHttpClient (); Request request = new Request.Builder () .url ("https://www.baidu.com") .build ()) Response response = null; String string = null; try {response = client.newCall (request). Execute (); string = response.body (). String ();} catch (IOException e) {e.printStackTrace () } String finalString = string; runOnUiThread (new Runnable () {@ Override public void run () {txt.setText (finalString);}});}}) .start ();}} 2. Realization of main layout

Activity_main.xml

5. Operation results

If the operation fails, it may be a problem with the simulator. It is recommended to change the simulator or use the real machine directly.

At this point, I believe you have a deeper understanding of what is okhttp and okio in the parsing of the Android network request framework, so you might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
