OkHttp简单使用

时间:2025-01-16 10:06:38

OkHttp是一个轻量优秀的网络框架。用于替代HttpUrlConnection和Apache HttpClient(android API23 6.0里已移除HttpClient,)

使用方法:

1、在 build.gradle中添加okHttp依赖 

 //okHttp
implementation 'com.squareup.okhttp3:okhttp:3.11.0'

2、创建一个全局的OkHttpClient 

//全局使用一个OkHttpClient
private static final OkHttpClient client=new OkHttpClient();

3、Get请求

public static String Get(String url) {
String result = null;
Request request = new Request.Builder()
.url(url)
.build();
try {
Response response = client.newCall(request).execute();
result = response.body().string();
} catch (IOException e) {
e.printStackTrace();
}
return result;
}

4、POST请求(通过键值对传递参数)

 public static String Post(String url, List<NameValuePair> paramList) {
String result = null;
FormBody.Builder builder = new FormBody.Builder();
for (NameValuePair param : paramList) {
builder.add(param.getName(), param.getValue());
}
FormBody formBody = builder.build();
Request request = new Request.Builder().url(url).post(formBody).build();
try {
Response response = client.newCall(request).execute();
result = response.body().string();
} catch (IOException e) {
e.printStackTrace();
}
return result;
}
