前面准备
1.gradle里面的依赖
implementation("com.squareup.okhttp3:okhttp:4.2.1")
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation("com.squareup.okhttp3:okhttp:4.2.1")//这一行
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
2.创建一个okhttp对象
//创建OkHttp
private final OkHttpClient okHttpClient = new OkHttpClient.Builder().build();
1.使用get方式
Request request = new Request.Builder()
.url("http://www.larryzy.com/addUser?account=121&pwd=2")
.build();
Call call = okHttpClient.newCall(request);
//进入队列等待执行
call.enqueue(new Callback() {
@Override
public void onFailure(@NotNull Call call, @NotNull IOException e) {
}
@Override
public void onResponse(Call call, Response response) throws IOException {
Log.i("tag", response.body().string());
}
});
2.使用post方式请求
RequestBody formBody = new FormBody.Builder().add("account", "800")
.add("pwd", "80")
.build();
Request request = new Request.Builder()
.url("http://www.larryzy.com/p/data")
.post(formBody)
.build();
Call call = okHttpClient.newCall(request);
call.enqueue(new Callback() {
@Override
public void onFailure(@NotNull Call call, @NotNull IOException e) {
}
@Override
public void onResponse(Call call, Response response) throws IOException {
Log.i("tag", response.body().string());
}
});
注意事项
1.response.body().string() 只能调用一次,否则报错
