Bitfinex有效负载错误V1 Java

Question

你能不能试着在这里查看我的代码。我从Bitfinex Api收到错误：线程“main”中的异常java.util.MissingResourceException：找不到服务器返回的HTTP响应代码：400为URL：https://api.bitfinex.com/v1/account_infos/ - > {“message”：“必须指定'请求'有效负载中与URL路径匹配的字段。“}

Answer 1

这两个被翻转：

jo.put(PATH, "request");
jo.put(getNonce(), "nonce");

他们应该是相反的：

jo.put("request", PATH);
jo.put("nonce", getNonce());
