如何在 OK-HTTP 标头中添加非 ASCII 字符串？

Question

我需要在请求的标头中添加一个 Base64 字符串。现在我的 base64 字符串是 mobileNum+pin 。这就是我生成编码字符串的方式：

public static String getAuthentication(String userName,String spin)
{
    String userCredentials = userName+":"+spin;
    String base64=null;
    try
    {
        byte[] data = userCredentials.getBytes("UTF-8");
        base64 = Base64.encodeToString(data, Base64.DEFAULT);
    }
    catch (UnsupportedEncodingException e){}

    String basicAuth = "Basic "+ new String(base64);

    return basicAuth;
}

而且，现在当我尝试从 Ok-HTTP 发出请求时，

Request request = new Request.Builder()
            .url(url+sp.getString("MOB",""))
            .get()
            .addHeader("xkey", ""+Auth.getApiKey())
            .addHeader("authorization",""+Auth.getAuthentication(sp.getString("MOB",""),sp.getString("SPIN","")))
            .addHeader("cache-control", "no-cache")
            .build();

它抛出异常，说：

 java.lang.IllegalArgumentException: Unexpected char 0x0a at 30 in authorization value: Basic OTE4MTExODExNjYwOjEyMzQ=

解决此问题的最佳方法是什么？

Answer 1

Basic OTE4MTExODExNjYwOjEyMzQ=
012345678901234567890123456789

你的字符串末尾有一些东西！

0xa = LF (Line Feed)

您可以在堆栈跟踪中看到换行符！

所以你的值末尾有一个无效的换行符。我看不到任何将添加它的代码。不要多次使用addHeader(...)，而是直接将值添加到标题中。

好的，如何正确使用它：

request request = new Request.Builder()
        .url(url+sp.getString("MOB",""))
        .get()
        .addHeader(
            new Headers.Builder().add("xkey", ""+Auth.getApiKey())
           .add("authorization",""+Auth.getAuthentication(sp.getString("MOB",""),sp.getString("SPIN","")))
           .add("cache-control", "no-cache")).build())
        .build();

好的，这段代码未测试过，它只是解释了你应该怎么做：使用一个新的标题生成器，添加键/值，然后通过调用build()创建标题

看看HeaderBuilder，看看HeaderBuilder！
