为HttpURLConnection添加标头 [英] Adding header for HttpURLConnection

问题描述

我正在尝试使用 HttpUrlConnection 为我的请求添加标头，但方法 setRequestProperty（）不会似乎工作。服务器端没有收到任何带有标题的请求。

I'm trying to add header for my request using HttpUrlConnection but the method setRequestProperty() doesn't seem working. The server side doesn't receive any request with my header.

HttpURLConnection hc;
    try {
        String authorization = "";
        URL address = new URL(url);
        hc = (HttpURLConnection) address.openConnection();


        hc.setDoOutput(true);
        hc.setDoInput(true);
        hc.setUseCaches(false);

        if (username != null && password != null) {
            authorization = username + ":" + password;
        }

        if (authorization != null) {
            byte[] encodedBytes;
            encodedBytes = Base64.encode(authorization.getBytes(), 0);
            authorization = "Basic " + encodedBytes;
            hc.setRequestProperty("Authorization", authorization);
        }

推荐答案

我使用了以下代码在过去，它曾在TomCat中启用基本身份验证：

I have used the following code in the past and it had worked with basic authentication enabled in TomCat:

URL myURL = new URL(serviceURL);
HttpURLConnection myURLConnection = (HttpURLConnection)myURL.openConnection();
String userCredentials = "username:password";
String basicAuth = "Basic " + new String(new Base64().encode(userCredentials.getBytes()));
myURLConnection.setRequestProperty ("Authorization", basicAuth);
myURLConnection.setRequestMethod("POST");
myURLConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
myURLConnection.setRequestProperty("Content-Length", "" + postData.getBytes().length);
myURLConnection.setRequestProperty("Content-Language", "en-US");
myURLConnection.setUseCaches(false);
myURLConnection.setDoInput(true);
myURLConnection.setDoOutput(true);

您可以尝试以上代码。上面的代码用于POST，你可以修改它为GET

You can try the above code. The code above is for POST, and you can modify it for GET
