okhttp使用

异步调用get

//创建okHttpClient对象
OkHttpClient mOkHttpClient = new OkHttpClient();
//创建一个Request
final Request request = new Request.Builder()
.url("https://github.com/hongyangAndroid")
.build();
//new call
Call call = mOkHttpClient.newCall(request);
//请求加入调度
call.enqueue(new Callback()
{
@Override
public void onFailure(Request request, IOException e)
{
}

@Override
public void onResponse(final Response response) throws IOException
{
//String htmlStr =  response.body().string();
}
});

异步调用post

Request request = buildMultipartFormRequest(
url, new File[]{file}, new String[]{fileKey}, null);
FormEncodingBuilder builder = new FormEncodingBuilder();
builder.add("username","name");

Request request = new Request.Builder()
.url(url)
.post(builder.build())
.build();
mOkHttpClient.newCall(request).enqueue(new Callback(){});

文件上传

File file = new File(Environment.getExternalStorageDirectory(), "balabala.mp4");

RequestBody fileBody = RequestBody.create(MediaType.parse("application/octet-stream"), file);

RequestBody requestBody = new MultipartBuilder()
.type(MultipartBuilder.FORM)
.addPart(Headers.of(
"Content-Disposition",
"form-data; name=\"username\""),
RequestBody.create(null, "张鸿洋"))
.addPart(Headers.of(
"Content-Disposition",
"form-data; name=\"mFile\";
filename=\"wjd.mp4\""), fileBody)
.build();

Request request = new Request.Builder()
.url("http://192.168.1.103:8080/okHttpServer/fileUpload")
.post(requestBody)
.build();

Call call = mOkHttpClient.newCall(request);
call.enqueue(new Callback()
{
//...
});

文件下载

OkHttpClientManager.downloadAsyn(
"http://192.168.1.103:8080/okHttpServer/files/messenger_01.png",
Environment.getExternalStorageDirectory().getAbsolutePath(),
new OkHttpClientManager.ResultCallback<String>()
{
@Override
public void onError(Request request, IOException e)
{

}

@Override
public void onResponse(String response)
{
//文件下载成功，这里回调的reponse为文件的absolutePath
}
});

同步get

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);
}
}

同步post

OkHttpClient client = new OkHttpClient();
String post(String url, String json) throws IOException {

RequestBody formBody = new FormEncodingBuilder()
.add("platform", "android")
.add("name", "bug")
.add("subject", "XXXXXXXXXXXXXXX")
.build();

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

Response response = client.newCall(request).execute();
if (response.isSuccessful()) {
return response.body().string();
} else {
throw new IOException("Unexpected code " + response);
}
}

public static final MediaType JSON = MediaType.parse("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();
Response response = client.newCall(request).execute();
f (response.isSuccessful()) {
return response.body().string();
} else {
throw new IOException("Unexpected code " + response);
}
}
