Description

A kind of Get of load server data succinct based on Android platform, efficient is asked Seek method

Technical field

It is the present invention relates to Android platform technical field, more particularly to a kind of succinct based on Android platform, efficient The Get request of load server data and can across Activity reception data method.

Background technology

Request server code complex redundancy, load data are slow in Android platform and can not across Activity solution The problem of analysing data；In order to solve these problems, it needs to Reseal the method for Get request and returned data processing to realize.

Invention content

Present invention solves the technical problem that be to provide a kind of succinct, efficient load server data Get request and Can across Activity reception data method；Solve request server code complex redundancy, load data slowly and can not be across Activity parses the problem of data.

The present invention solve above-mentioned technical problem technical solution be：

In tool-class create a basic Get method, parameter have url, Map type of String types params, The callback of the Callback types and cancel of Boolean type adds some in params parameters and fixed asks first It asks parameter information, traversal parameter to be spliced in url, url is added by request variables and is built, is then used GetInstance singleton methods obtain OkHttpClient client variables, initiate network request using client and ask, Get methods are finally made carbon copies, the data of return are handled in callback method.It is based on Android platform request to solve Code server complex redundancy, load data slowly and can not across Activity parsing data the problem of.

The method specifically comprises the following steps：

Step 1: creating tool-class HttpUtils in Android projects, static variable OkHttpClient is defined MOkHttpClient is initialized by singleton pattern method；

Step 2: create a basic Get method, parameter have url, Map type of String types params, The callback of the Callback types and cancel of Boolean type；

Step 3: adding some fixed required parameter information in params parameters in Get methods, traversal parameter is spliced to In url, url is added by request variables and is built, then getInstance singleton methods is used to obtain OkHttpClient client variables are initiated network request using client and are asked；

Step 4: the BaseEvent classes of general type are created, for parsing data；

Step 5: manifolding Get methods, and newly-increased BaseEvent event parameters, realize onFailure in callback with OnResponse methods；

Step 6: obtaining the json data returned in onResponse, it is added in event, passes through the post of EventBus (event) message with data is sent;

Step 7: in any Activity pages, data are received by onEventMainThread methods.

Beneficial effects of the present invention：In tool-class create a basic Get method, parameter have String types url, The callback of params, Callback type of the Map types and cancel of Boolean type, first in params parameters Some fixed required parameter information are added, traversal parameter is spliced in url, is added url by request variables and is built, Then it uses getInstance singleton methods to obtain OkHttpClient client variables, network is initiated using client Request is asked, and finally makes carbon copies Get methods, the data of return are handled in callback method, succinct, efficient to reach The purpose of across the Activity parsing data of request server.Effectively solve based on Android platform request server generation Code complex redundancy, load data slowly and can not across Activity parsing data the problem of.

Description of the drawings

The following further describes the present invention with reference to the drawings：

Fig. 1 is the flow chart of the present invention.

Specific implementation mode

As shown in Figure 1, the present invention uses following steps：

Step 1: creating tool-class HttpUtils in Android projects, static variable OkHttpClient is defined MOkHttpClient is initialized by singleton pattern method；Such as：

public class HttpUtils{

private static OkHttpClient mOkHttpClient;

private static final int TIMEOUT_CONNECT_SECOND = 10;// connection time-out time, it is single Position:Second

private static final int TIMEOUT_WRITE_SECOND = 10;// time-out time is read, it is single Position:Second

private static final int TIMEOUT_READ_SECOND = 30;// write-in time-out time, unit: Second

public static OkHttpClient getInstance() {

if (mOkHttpClient == null) {

mOkHttpClient=newOkHttpClient();

mOkHttpClient.setConnectTimeout(TIMEOUT_CONNECT_SECOND, TimeUnit.SECONDS);

mOkHttpClient.setWriteTimeout(TIMEOUT_WRITE_SECOND, TimeUnit.SECONDS);

mOkHttpClient.setReadTimeout(TIMEOUT_READ_SECOND, TimeUnit.SECONDS);

}

return mOkHttpClient;

}

}

Step 2: create a basic Get method, parameter have url, Map type of String types params, The callback of the Callback types and cancel of Boolean type；Such as：

public static void get(String url, Map<String, String> params, Callback callback, boolean cancel) {}

Step 3: adding some fixed required parameter information in params parameters in Get methods, traversal parameter is spliced to In url, url is added by request variables and is built, then getInstance singleton methods is used to obtain OkHttpClient client variables are initiated network request using client and are asked；Such as：

public static void get(String url, Map<String, String> params, Callback callback, boolean cancel) {

Set<String> keys = params.keySet();

String str = "token=aaaa&pwd=bbbbbbbb";

for (String key : keys) {

String value = params.get(key);

str+=…..;

}

if (!url.startsWith("http")){

url = …..;

}

Request request = new Request.Builder().url(url).build();

OkHttpClient client = getInstance();

if (cancel) {

client.cancel(Api.host + url);

}

client.newCall(request).enqueue(callback);

}

Step 4: the BaseEvent classes of general type are created, for parsing data；Such as：

public class BaseEvent<T> {

public static final int REQUEST_SUCCESS = 1;

public static final int NETWORK_UNAVAILABLE = 2;

public static final int REQUEST_FAILURE = -1;

protected String resultJson;

protected int resultType;

protected T data;

public boolean isRequestSuccess () {

Code omits ----

}

Get and set methods ...

}

Step 5: manifolding Get methods, and newly-increased BaseEvent event parameters, realize onFailure in callback with OnResponse methods；Such as：

public static void get(String url, Map<String, String> params, final BaseEvent event, boolean cancel) {

get(url, params, new Callback() {

@Override

public void onFailure(Request request, IOException e) {

}

@Override

public void onResponse(Response response) throws IOException {

}

}, cancel);

}

Step 6: obtaining the json data returned in onResponse, it is added in event, passes through the post of EventBus (event) message with data is sent;Such as：

public static void get(String url, Map<String, String> params, final BaseEvent event, boolean cancel) {

get(url, params, new Callback() {

@Override

public void onFailure(Request request, IOException e) {

event.setResultType(BaseEvent.REQUEST_FAILURE);

EventBus.getDefault().post(event);

}

@Override

public void onResponse(Response response) throws IOException {

String resultJson = response.body().string();

event.setResultJson(resultJson);

event.setResultType(BaseEvent.REQUEST_SUCCESS);

// event signal with data is sent in activity

EventBus.getDefault().post(event);

}

}, cancel);

}

Step 7: in any Activity pages, data are received by onEventMainThread methods.Such as：

public void onEventMainThread(BaseEvent event) {

if (event.isRequestSuccess()) {

Intent intent = new Intent(getActivity(), OtherActivity.class);

intent.putExtra(“data”, event.getData().toString());

getActivity().startActivity(intent);

} else {

ToastUtil.showLong (getActivity (), " request failures, reason：" + event.getErrorMessage());

}

}
