OKhttp PUT example

问题

My requirement is to use PUT, send a header and a body to server which will update something in the database.

I just read okHttp documentation and I was trying to use their POST example but it doesn't work for my use case (I think it might be because the server requires me to use PUT instead of POST).

This is my method with POST:

 public void postRequestWithHeaderAndBody(String url, String header, String jsonBody) {


        MediaType JSON = MediaType.parse("application/json; charset=utf-8");
        RequestBody body = RequestBody.create(JSON, jsonBody);

        OkHttpClient client = new OkHttpClient();

        Request request = new Request.Builder()
                .url(url)
                .post(body)
                .addHeader("Authorization", header)
                .build();

        makeCall(client, request);
    }

I have tried to search for okHttp example using PUTwith no success, if I need to use PUTmethod is there anyway to use okHttp?

I'm using okhttp:2.4.0 (just in case), thanks on any help!

Change your .post with .put

public void putRequestWithHeaderAndBody(String url, String header, String jsonBody) {


        MediaType JSON = MediaType.parse("application/json; charset=utf-8");
        RequestBody body = RequestBody.create(JSON, jsonBody);

        OkHttpClient client = new OkHttpClient();

        Request request = new Request.Builder()
                .url(url)
                .put(body) //PUT
                .addHeader("Authorization", header)
                .build();

        makeCall(client, request);
    }

Use put method instead of post

Request request = new Request.Builder()
            .url(url)
            .put(body) // here we use put
            .addHeader("Authorization", header)
            .build();

OkHttp Version 2.x

If you're using OkHttp Version 2.x, use the following:

OkHttpClient client = new OkHttpClient();

RequestBody formBody = new FormEncodingBuilder()
        .add("Key", "Value")
        .build();

Request request = new Request.Builder()
    .url("http://www.foo.bar/index.php")
    .put(formBody)  // Use PUT on this line.
    .build();

Response response = client.newCall(request).execute();

if (!response.isSuccessful()) {
    throw new IOException("Unexpected response code: " + response);
}

System.out.println(response.body().string());

OkHttp Version 3.x

As OkHttp version 3 replaced FormEncodingBuilder with FormBody and FormBody.Builder(), for versions 3.x you have to do the following:

OkHttpClient client = new OkHttpClient();

RequestBody formBody = new FormBody.Builder()
        .add("message", "Your message")
        .build();

Request request = new Request.Builder()
        .url("http://www.foo.bar/index.php")
        .put(formBody) // PUT here.
        .build();

try {
    Response response = client.newCall(request).execute();

    // Do something with the response.
} catch (IOException e) {
    e.printStackTrace();
}
