概述
1、加入对okhttp的依赖
在app的build.gradle当中的
dependencies{
}标签中加入依赖
compile 'com.squareup.okhttp3:okhttp:3.3.1'2、okhttpclient3、http get（同步）client = new OkHttpClient();
需要新建立一个子线程，对于超过1MB的响应body，应使用流的方式来处理body。
private void syncGet() { new Thread() { @Override public void run() { Request request = new Request.Builder() .url("http://publicobject.com/helloworld.txt") .build(); Call call = client.newCall(request); try { Response response = call.execute(); if (!response.isSuccessful()) { throw new IOException("Unexpected code " + response); } Headers responseHeaders = response.headers(); for (int i = 0; i < responseHeaders.size(); i++) { Log.d(TAG, responseHeaders.name(i) + ": " + responseHeaders.value(i)); } Log.d(TAG, "body===>" + response.body().string()); } catch (IOException e) { e.printStackTrace(); } } }.start(); }结果：4、异步http get
private void asynchronousGet() { Request request = new Request.Builder() .url("http://publicobject.com/helloworld.txt") .build(); Call call = client.newCall(request); call.enqueue(new Callback() { @Override public void onFailure(Call call, IOException e) { e.printStackTrace(); } @Override public void onResponse(Call call, Response response) throws IOException { if (!response.isSuccessful()) { throw new IOException("Unexpected code " + response); } Headers responseHeaders = response.headers(); for (int i = 0; i < responseHeaders.size(); i++) { Log.d(TAG, responseHeaders.name(i) + "=====> " + responseHeaders.value(i)); } Log.d(TAG, "body===>" + response.body().string()); } }); }
结果：
5、提取响应头
private void getresponseHeader() { new Thread() { @Override public void run() { Request request = new Request.Builder() .url("https://api.github.com/repos/square/okhttp/issues") .header("User-Agent", "OkHttp Headers.java") .addHeader("Accept", "application/json; q=0.5") .addHeader("Accept", "application/vnd.github.v3+json") .build(); Response response = null; try { response = client.newCall(request).execute(); if (!response.isSuccessful()) throw new IOException("Unexpected code " + response); Log.d(TAG, "Server: " + response.header("Server")); Log.d(TAG, "Date: " + response.header("Date")); Log.d(TAG, "Vary: " + response.headers("Vary")); } catch (IOException e) { e.printStackTrace(); } } }.start(); }
结果：
07-04 11:49:25.644 4300-4340/com.example.okhttpdemo D/MainActivity: Server: GitHub.com 07-04 11:49:25.644 4300-4340/com.example.okhttpdemo D/MainActivity: Date: Tue, 04 Jul 2017 03:49:23 GMT 07-04 11:49:25.644 4300-4340/com.example.okhttpdemo D/MainActivity: Vary: [Accept, Accept-Encoding, Accept-Encoding]
6、http post提交String
private void postString() { new Thread() { @Override public void run() { String postBody = "" + "Releasesn" + "--------n" + "n" + " * _1.0_ May 6, 2013n" + " * _1.1_ June 15, 2013n" + " * _1.2_ August 11, 2013n"; Request request = new Request.Builder() .url("https://api.github.com/markdown/raw") .post(RequestBody.create(MEDIA_TYPE_MARKDOWN, postBody)) .build(); Call call = client.newCall(request); Response response = null; try { response = call.execute(); if (!response.isSuccessful()) throw new IOException("Unexpected code " + response); Log.d(TAG, "body====>" + response.body().string()); } catch (IOException e) { e.printStackTrace(); } } }.start(); }
结果：
7、post stream
private void postStream() { new Thread() { @Override public void run() { RequestBody requestBody = new RequestBody() { @Override public MediaType contentType() { return MEDIA_TYPE_MARKDOWN; } @Override public void writeTo(BufferedSink sink) throws IOException { sink.writeUtf8("Numbersn"); sink.writeUtf8("-------n"); for (int i = 2; i <= 997; i++) { sink.writeUtf8(String.format(" * %s = %sn", i, factor(i))); } } private String factor(int n) { for (int i = 2; i < n; i++) { int x = n / i; if (x * i == n) return factor(x) + " × " + i; } return Integer.toString(n); } }; Request request = new Request.Builder() .url("https://api.github.com/markdown/raw") .post(requestBody) .build(); Response response = null; try { response = client.newCall(request).execute(); if (!response.isSuccessful()) throw new IOException("Unexpected code " + response); Log.d(TAG, "body--->" + response.body().string()); } catch (IOException e) { e.printStackTrace(); } } }.start(); }
结果：
8、post file
我在android手机根目录下放置了一个file.txt文件，文件里面的内容是123456
打印结果：private void postFile() { new Thread() { @Override public void run() { File file = new File("/mnt/sdacard/360sicheck.txt"); Request request = new Request.Builder() .url("https://api.github.com/markdown/raw") .post(RequestBody.create(MEDIA_TYPE_MARKDOWN, file)) .build(); Response response = null; try { response = client.newCall(request).execute(); if (!response.isSuccessful()) throw new IOException("Unexpected code " + response); Log.d(TAG, "body===>" + response.body().string()); } catch (IOException e) { e.printStackTrace(); } } }.start(); }
07-04 13:42:27.510 25669-25794/com.example.okhttpdemo D/MainActivity: body===><p>123456</p>
9、post提交表单
private void postForm() { new Thread() { @Override public void run() { RequestBody formBody = new FormBody.Builder() .add("search", "Jurassic Park") .build(); Request request = new Request.Builder() .url("https://en.wikipedia.org/w/index.php") .post(formBody) .build(); Response response = null; try { response = client.newCall(request).execute(); if (!response.isSuccessful()) throw new IOException("Unexpected code " + response); Log.d(TAG, "body===>" + response.body().string()); } catch (IOException e) { e.printStackTrace(); } } }.start(); }
打印结果：
07-04 13:50:17.949 1822-2120/com.example.okhttpdemo D/MainActivity: body===><!DOCTYPE html>
<html class="client-nojs" lang="en" dir="ltr">

mw.user.tokens.set({"editToken":"+\","patrolToken":"+
10、post提交json
Gson是一个在JSON和Java对象之间转换非常方便的api。这里我们用Gson来解析Github API的JSON响应。
注意：ResponseBody.charStream()使用响应头Content-Type指定的字符集来解析响应体。默认是UTF-8。
private void postJson() { new Thread() { @Override public void run() { Request request = new Request.Builder() .url("https://api.github.com/gists/c2a7c39532239ff261be") .build(); Response response = null; try { response = client.newCall(request).execute(); if (!response.isSuccessful()) throw new IOException("Unexpected code " + response); Gist gist = gson.fromJson(response.body().charStream(), Gist.class); for (Map.Entry<String, GistFile> entry : gist.files.entrySet()) { Log.d(TAG, "key===>" + entry.getKey()); Log.d(TAG, "content===>" + entry.getValue().content); } } catch (IOException e) { e.printStackTrace(); } } }.start(); }
打印结果：
