1.未封装的Okhttp
private OkHttpClient client = new OkHttpClient();
FormEncodingBuilder builder = new FormEncodingBuilder();
builder.add("accountName",user);
builder.add("password",password);
Request request = new Request.Builder()
.url("www.baidu.com")
.post(builder.build())
.build();
client.newCall(request).enqueue(new com.squareup.okhttp.Callback() {
@Override
public void onFailure(Request request, IOException e) {
}
@Override
public void onResponse(Response response) throws IOException {
// Log.e("response",response.body().string());
ParseJson(response.body().string());
}
});以上就是简单的okhttp网络请求
2.封装好的网络请求：
