Okhttp常用方法示例

这是我用到的一个util类

public class HttpBaseService {

    private OkHttpClient client = new OkHttpClient();
    private static final MediaType JSON = MediaType.parse("application/json; charset=utf-8");
    public String sendGetRequest(String url){
        Request request = new Request.Builder().url(url).build();
        Response response = null;
        try {
            response = client.newCall(request).execute();
            if (response.isSuccessful()) {
                return response.body().string();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return "";
    }

    public int sendDelRequest(String url){
        Request request = new Request.Builder().url(url).delete().build();
        return sendOperateRequest(request);
    }

    public int sendPostRequest(String url,String json){
//        RequestBody formBody = new FormEncodingBuilder()
//                .add("platform", "android")
//                .add("name", "bug")
//                .add("subject", "XXXXXXXXXXXXXXX")
//                .build();
        RequestBody body = RequestBody.create(JSON,json);
        Request request = new Request.Builder().url(url).post(body).build();
        return sendOperateRequest(request);
    }
    public int sendPutRequest(String url,String json){
        RequestBody body = RequestBody.create(JSON,json);
        Request request = new Request.Builder().url(url).put(body).build();
        return sendOperateRequest(request);
    }

    private int sendOperateRequest(Request request){
        Response response = null;
        try {
            response = client.newCall(request).execute();
            if (response.isSuccessful()) {
                return 0;
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return -1;
    }
}
