Question

    OAuthClient oAuthClient = new OAuthClient(new URLConnectionClient());
    TokenRequestBuilder r = OAuthClientRequest
            .tokenLocation("https://www.linkedin.com/oauth/v2/accessToken")
            .setCode(code)
            .setGrantType(GrantType.AUTHORIZATION_CODE)

    Map<String,String> m = new HashMap<String,String>();
    m.put("Content-Type", "application/x-www-form-urlencoded");

    int bodyLength = r.buildBodyMessage().getBody().length();
    System.out.println("Body l = " + bodyLength);
    m.put("Content-Length", Integer.toString(bodyLength));
    r.buildHeaderMessage().setHeaders(m);
    OAuthClientRequest request = r.buildQueryMessage();
    OAuthJSONAccessTokenResponse tk = oAuthClient.accessToken(request, OAuth.HttpMethod.POST);

Answer 1

您需要发送一个POST请求，在body中包含params，Urlenconded...所以

第一个变化：

OAuthClientRequest request = r.buildQueryMessage();

与：

OAuthClientRequest request = r.buildBodyMessage();
