在Android中使用OkHttp客户端时，标头值中出现意外的char 0x0a [英] Unexpected char 0x0a in header value when using OkHttp client in Android

问题描述

当使用Http发送Base64编码的字符串作为标头时，我得到的错误响应为

When sending a Base64 encoded string as header using Http, I am getting error response as

Unexpected char 0x0a at 28 in header value: I99Uy+HjG5PpEhmi8vZgm0W7KDQ=

用法:

String encodedHeader = Base64.encodeToString(value.getBytes(), Base64.DEFAULT); header.put("auth", encodedHeader);

String encodedHeader = Base64.encodeToString(value.getBytes(), Base64.DEFAULT); header.put("auth", encodedHeader);

推荐答案

0x0a是换行符，标头中禁止使用. 解决方案是在发送编码后的值作为标头之前，确保将这些字符剥离掉.

0x0a is a newline character which is forbidden in a header. Solution would be to make sure that these characters are stripped off before sending the encoded value as header.

Base64.encodeToString(credentials.getBytes(), Base64.NO_WRAP); 这样可以避免使用平台特定的换行符.

Base64.encodeToString(credentials.getBytes(), Base64.NO_WRAP); this avoids wrapping with a platform specific newline character(s).
