Android网络请求之OkHttp
OkHttp是一个第三方类库，用于android中请求网络。这是一个开源项目,是安卓端最火热的轻量级框架,由移动支付Square公司贡献(该公司还贡献了Picasso和LeakCanary)。用于替代HttpUrlConnection和Apache
HttpClient(android API23 里已移除HttpClient)
OkHttp是一款优秀的HTTP框架，它支持get请求和post请求，支持基于Http的文件上传和下载，支持加载图片，支持下载文件透明的GZIP压缩，支持响应缓存避免重复的网络请求，支持使用连接池来降低响应延迟问题
Get请求OkHttpClient client = new OkHttpClient();
String run(String url) throws IOException {
Request request = new Request.Builder().url(url).build();
Response response = client.newCall(request).execute();
if (response.isSuccessful()) {
return response.body().string();
} else {
throw new IOException("Unexpected code " + response);
}
}
Post请求
public static final MediaType JSON = MediaType.get("application/json; charset=utf-8");
OkHttpClient client = new OkHttpClient();
String post(String url, String json) throws IOException {
RequestBody body = RequestBody.create(json, JSON);
Request request = new Request.Builder()
.url(url)
.post(body)
.build();
try (Response response = client.newCall(request).execute()) {
return response.body().string();
}
}
