1.签名看文档写包含服务商ID

那么是这样写么，这样写一直报签名错误

"sp_mchid=\"" + WxPayPartnerConfig.sp_mchid + "\","
        + "sub_mchid=\"" + WxPayPartnerConfig.sub_mchid  + "\","
        + "nonce_str=\"" + WxPayPartnerConfig.nonceStr  + "\","
        + "timestamp=\"" + WxPayPartnerConfig.timestamp + "\","
        + "serial_no=\"" + WxPayPartnerConfig.serial_no + "\","
        + "signature=\"" + signature + "\"";

下面不是服务商如下写OK

2.配置的证书和证书序列号是服务商的对么？
