异常信息很清楚,这个方法定义了2个请求体。

public String toPayHtml(String channelId, String payToken)

啊?该怎么解决,大哥

public interface PayContextService {

    @GetMapping("/toPayHtml")
    public BaseResponse<JSONObject> toPayHtml(String channelId, String payToken);
}

这是我支付service的代码

只定义一个请求体。用对象封装参数,。

@Controller
public class PayController {
    @Autowired
    private PayContextServiceFeign payContextServiceFeign;
    @GetMapping("/toPayHtml")
    public String toPayHtml(PayVo payVo) {
        BaseResponse<JSONObject> jsonObjectBaseResponse = payContextServiceFeign.toPayHtml(payVo.getChannelId(), payVo.getPayToken());
        JSONObject data = jsonObjectBaseResponse.getData();
        String payHtml = data.getString("payHtml");
        return payHtml;
    }
}

这个样子吗

是这个 PayContextService。这个被feign代理了。

还是懵的 :joy:

feign那个的参数你加上@RequestParam(name=“”)就行
