4、AntiFakeController

@ApiParam("品牌ID") @RequestParam("brandId") Integer brandId) {
AntiFake antiFake = antiFakeService.findByCode(code);
if (antiFake == null) {
return BaseResult.failure(601, "当前防伪码不存在");
}
if (!brandId.equals(antiFake.getBrandId())) {
return BaseResult.failure(604, "非当前品牌防伪码");
}
BaseResult result = null;
switch (antiFake.getStatus()) {
case AntiFake.STATUS_UNACTIVAT:
result = BaseResult.failure(602, "当前防伪码未激活");
break;
case AntiFake.STATUS_LOCKED:
result = BaseResult.failure(603, "当前防伪码已被锁定");
break;
case AntiFake.STATUS_NORMAL:
result = BaseResult.success();
if (antiFake.getCheckNumber() == 0) {
antiFake.setFirstCheckDate(new Date());
}
antiFake.setCheckNumber(antiFake.getCheckNumber() + 1);
antiFake = antiFakeService.save(antiFake);
break;
default:
}
AntiFakeCheckRecord antiFakeCheckRecord = new AntiFakeCheckRecord();
antiFakeCheckRecord.setAntiFakeId(antiFake.getId());
antiFakeCheckRecord.setLatitude(latitude);
antiFakeCheckRecord.setLongitude(longitude);
antiFakeCheckRecord.setAddress(AddressUtil.getAddress(latitude, longitude));
antiFakeCheckRecord.setUnionId(unionId);
antiFakeCheckRecord.setResult(result.getMsg());
antiFakeCheckRecord.setCheckNumber(antiFake.getCheckNumber());
antiFakeCheckRecordService.save(antiFakeCheckRecord);
result.setData(antiFake);
return result;
}
}
5、解决方案
在你的后端代码中，check 方法使用了 @RequestParam 注解来接收 code、latitude、longitude、unionId 和 brandId 参数。这意味着这些参数应当以查询参数的形式传递，而不是以 JSON 格式发送在请求体中。
要解决 MissingServletRequestParameterException 问题，可以从前端发送请求时确保参数按 application/x-www-form-urlencoded 或 URL 查询参数形式传递。以下是几种处理方式：
方案一：修改前端请求格式
在前端将数据改为 URL 查询字符串格式，并设置请求头为 application/x-www-form-urlencoded，如下所示：
const requestData = `code=${code}&latitude=${latitude}&longitude=${longitude}&unionId=${unionId}&brandId=${brandId}`;
wx.request({
url: 'http://localhost:8087/antiFake/check',
method: 'POST',
data: requestData,
header: {
'token': token,
'Content-Type': 'application/x-www-form-urlencoded'
},
success: resolve,
fail: reject
});
方案二：拼接 URL 参数（适用于 GET 请求或带参数的 POST 请求）
如果后端允许将请求参数直接作为 URL 查询参数传递，可以将参数拼接到 URL 中：
const url = `http://localhost:8087/antiFake/check?code=${code}&latitude=${latitude}&longitude=${longitude}&unionId=${unionId}&brandId=${brandId}`;
wx.request({
url: url,
method: 'POST',
header: {
'token': token,
'Content-Type': 'application/json'
},
success: resolve,
fail: reject
});
方案三：后端改用 @RequestBody
如果必须以 JSON 格式发送请求体，建议将后端方法的参数改为 @RequestBody，使其接收 JSON 格式数据：
@PostMapping("check")
public BaseResult check(@RequestBody Map<String, Object> requestData) {
String code = (String) requestData.get("code");
String latitude = (String) requestData.get("latitude");
String longitude = (String) requestData.get("longitude");
String unionId = (String) requestData.get("unionId");
Integer brandId = (Integer) requestData.get("brandId");
// 接下来的逻辑保持不变
}
这样前端可以继续使用 JSON 格式发送数据，不需要修改请求头。
总结
如果你不想修改后端代码，建议使用方案一或方案二，以确保 @RequestParam 能正确接收到数据。
