当我尝试设置 header 时出现 Volley 投掷错误
Volley throwing error when I try to set a header
当我向我的 Volley
字符串请求添加自定义 header 时,我收到一条错误消息 Unexpected char 0x0a at 18 in header value
。
这是我的代码。
stringRequest = new StringRequest(Request.Method.GET, URL, string -> {
try {
JSONObject jsonObject = new JSONObject(string);
Log.d("TAG", jsonObject.toString());
} catch (Exception e) {
}
}, error -> {
}){
@Override
public Map<String, String> getHeaders() {
Map<String, String> params = new HashMap<>();
params.put("MIME Type", "application/x-www-form-urlencoded; charset=UTF-8");
params.put("compiler", "c");
params.put("code", code);
params.put("input", "");
return params;
}
};
我遇到的错误。

0x0A 是 \n 换行符。确保在你的 header 中没有 "\n".
我认为在您的 header 中您有一些台词!
您可以使用 body!

解决了它
• 第 1 步:移除 params.put("MIME Type", "application/x-www-form-urlencoded; charset=UTF-8");
• 第 2 步:将 params.put("code", code);
替换为 params.put("code", Base64.encodeToString(code.getBytes(), Base64.NO_WRAP));
更新
• 我已从我的代码中删除了第 2 步,因为它给我带来了问题。所以现在看起来像 params.put("code", code);
