CURL POST请求至服务器后请求体解析失败问题求助

问题说明 #

通过服务端发送CURL POST请求至自有服务器，但请求体无法被正确解析，服务器返回异常嵌套的结构。

请求示例 #

原CURL命令：

curl -d '{"merchantAccount":"pipedrive_youscore_rubicon_ltd","orderReference":"WFP-BTN-7181819-635e48482b33d","merchantSignature":"7bf****************c","amount":3,"currency":"UAH","authCode":"326470","email":"rubicon.sergii@gmail.com","phone":"380669114250","createdDate":1667123272,"processingDate":1667123284,"cardPan":"44****6705","cardType":"Visa","issuerBankCountry":"Ukraine","issuerBankName":"MONObank","recToken":"","transactionStatus":"Approved","reason":"Ok","reasonCode":1100,"fee":0.07,"paymentSystem":"googlePay","acquirerBankName":"WayForPay","cardProduct":"credit","clientName":"Rubicon Sergii","products":[{"name":"Тестовий товар","price":3,"count":1}],"clientFields":[{"name":"Домен порталу","value":"rawgsag"}]}' http://app.rubicon.tips:3000/checkSupPay

服务器异常返回 #

'{"merchantAccount":"pipedrive_youscore_rubicon_ltd","orderReference":"WFP-BTN-7181819-6361151577ee8","merchantSignature":"5f0f*************bc6536a98dd","amount":3,"currency":"UAH","authCode":"126496","email":null,"phone":null,"createdDate":1667306773,"processingDate":1667307818,"cardPan":"","cardType":null,"issuerBankCountry":null,"issuerBankName":null,"recToken":"","transactionStatus":"Refunded","reason":"Ok","reasonCode":1100,"fee":0,"paymentSystem":"googlePay","acquirerBankName":"WayForPay","cardProduct":"credit","clientName":null,"products":': {
    '{"name":"\u0422\u0435\u0441\u0442\u043e\u0432\u0438\u0439 \u0442\u043e\u0432\u0430\u0440","price":3,"count":1}': {
      '{"name":"\u0414\u043e\u043c\u0435\u043d \u043f\u043e\u0440\u0442\u0430\u043b\u0443","value":"qh34hh44h"}': ''
    }
  }
}

已尝试方案 #

使用bodyParser.urlencoded({ extended: true })和bodyParser.json()中间件解析请求体，均无效。

解决步骤 #

1. 修正CURL请求的Content-Type头 #

CURL的-d参数默认会设置Content-Type: application/x-www-form-urlencoded，但请求体是JSON格式，服务器的bodyParser.json()只会解析Content-Type为application/json的请求，必须显式添加请求头：

curl -H "Content-Type: application/json" -d '{"merchantAccount":"pipedrive_youscore_rubicon_ltd","orderReference":"WFP-BTN-7181819-635e48482b33d","merchantSignature":"7bf****************c","amount":3,"currency":"UAH","authCode":"326470","email":"rubicon.sergii@gmail.com","phone":"380669114250","createdDate":1667123272,"processingDate":1667123284,"cardPan":"44****6705","cardType":"Visa","issuerBankCountry":"Ukraine","issuerBankName":"MONObank","recToken":"","transactionStatus":"Approved","reason":"Ok","reasonCode":1100,"fee":0.07,"paymentSystem":"googlePay","acquirerBankName":"WayForPay","cardProduct":"credit","clientName":"Rubicon Sergii","products":[{"name":"Тестовий товар","price":3,"count":1}],"clientFields":[{"name":"Домен порталу","value":"rawgsag"}]}' http://app.rubicon.tips:3000/checkSupPay

2. 验证服务器端中间件配置 #

• 确保bodyParser.json()（或Express 4.16+内置的express.json()）在路由之前注册，示例代码：

  const express = require('express');
  const app = express();
  
  // 优先注册JSON解析中间件
  app.use(express.json()); // 替代bodyParser.json()，Express 4.16+内置
  
  app.post('/checkSupPay', (req, res) => {
    console.log('解析后的请求体:', req.body);
    res.send({ status: 'success', data: req.body });
  });
  
  app.listen(3000, () => console.log('服务器运行在3000端口'));
  

• 若仍使用bodyParser包，需确保已安装并正确引入：

  npm install body-parser
  

  const bodyParser = require('body-parser');
  app.use(bodyParser.json());
  

3. 检查请求体合法性 #

确认请求体是标准JSON格式：

• 所有字符串用双引号包裹（不要用单引号）
• 数组和对象的括号配对正确
• 特殊字符（如乌克兰语）编码为UTF-8，服务器端需确保支持UTF-8解析
