Android OkHttp Tutorial

First introduce the simple use of okhttp:

• A general GET request
• General POST request
• HTTP-based file upload
• File download
• Loading pictures
• Support Request callback, return object, object collection directly
• Support for session retention

In Android Studio, you can choose to add dependencies

compile ‘com.squareup.okhttp:okhttp:2.4.0‘
compile ‘com.squareup.okio:okio:1.5.0‘

(i) Http Get

//Create Okhttpclient object okhttpclient mokhttpclient =new Okhttpclient ();//Create a requestFinal Request Request =new Request.builder (). URL ("Https://github.com/hongyangAndroid"). Build ();//new Callcall call = Mokhttpclient.newcall (request);//Request Join Schedule Call.enqueue (New Callback () {@Override Publicvoid  onfailure (Request request, IOException e) {}  @ Override  public  void  onresponse ( final Response Response)  Span class= "Hljs-keyword" >throws ioexception { < Span style= "FONT-SIZE:16PX;" >//string htmlstr = Response.body (). String (); } }); 
  Response.body (). String ()  get string 
  response.body (). Bytes ()  get binary byte array 
  Response.body (). ByteStream ()  get input stream 
          

(ii) Http Post carrying parameters

Request request = buildMultipartFormRequest(        new File[]{file}, new String[]{fileKey}, null);FormEncodingBuilder builder = new FormEncodingBuilder(); builder.add("username","张鸿洋");Request request = new Request.Builder() .url(url) .post(builder.build()) .build(); mOkHttpClient.newCall(request).enqueue(new Callback(){});
