Okhttp3.8.1

FormBody.Builder

protected void appendParams(FormBody.Builder builder, Map, String> params) {

    if (params != null && !params.isEmpty()) {
        for (String key : params.keySet()) {
            builder.add(key, params.get(key));
        }
    }
}

注意了会进行Url编码。重要事情说三遍， 会进行Url编码，会进行Url编码，会进行Url编码
