考虑：
fastify.get("/paynow", (request, reply) => {
let data = {
TXN_AMOUNT: '10', // request amount
ORDER_ID: 'ORDER_123455', // any unique order id
CUST_ID: 'CUST_1238w4' // any unique customer id
}
// Create Paytm Payment
paytm.createPayment(config, data, function (err, data) {
if (err) {
// Handle error
}
// Store the URL and checksum
let url = data.url;
let checksum = data.checksum;
// Delete it from the data object
delete data.url;
delete data.checksum;
/* Prepare HTML Form and Submit to Paytm */
reply.type('text/html');
reply.raw.writeHead(200, { 'Content-Type': 'text/html' });
reply.header('Content-Type', 'application/x-www-form-urlencoded');
reply.header("Access-Control-Allow-Origin", "*");
reply.header("Access-Control-Expose-Headers", "Content-Range");
reply.header(
"Access-Control-Allow-Headers",
"Origin, X-Requested-With, Content-Type, Accept, Authorization"
);
reply.raw.write('<html>');
reply.raw.write('<head>');
reply.raw.write('<title>Merchant Checkout Page</title>');
reply.raw.write('</head>');
reply.raw.write('<body>');
reply.raw.write('<center><h1>Please do not refresh this page...</h1></center>');
reply.raw.write('<form method="post" action="' + url + '" name="paytm_form">');
for (var x in data) {
reply.raw.write('<input type="hidden" name="' + x + '" value="' + data[x] + '">');
}
reply.raw.write('<input type="hidden" name="CHECKSUMHASH" value="' + checksum + '">');
reply.raw.write('</form>');
reply.raw.write('<script type="text/javascript">');
reply.raw.write('document.paytm_form.submit();');
reply.raw.write('</script>');
reply.raw.write('</body>');
reply.raw.write('</html>');
reply.raw.write('ok')
reply.raw.end();
});
});
fastify.post('/true', (request, reply) => {
console.log('*')
paytm.validate(config, request.body, function (err, data) {
console.log(data)
if (err) {
// handle err
console.log(err)
}
if (data.status == 'verified') {
// Mark payment done in your db
}
});
});
Paynow API 工作正常，但当它重定向到 /true 路由时，出现错误：
{"statusCode":415,"code":"FST_ERR_CTP_INVALID_MEDIA_TYPE","error":"不支持 媒体类型","message":"不支持的媒体类型: 应用程序/x-www-form-urlencoded"}
我认为这与fastify有关。我真的不知道，因为这是我使用 fastify 的第一个项目。我该如何解决它？
Fastify，开箱即用，仅解析
application/json要管理表单，您需要将这些插件添加到您的项目中
application/x-www-form-urlencodedmultipart/form-data为了完整起见，我需要除了这两个之外的其他东西（我需要多部分/相关）。您可以在 Fastify 实例上使用“addContentTypeParser”添加您自己的内容类型解析器。
https://www.fastify.io/docs/latest/Reference/Server/#addcontenttypeparser
Fastify 推荐使用 @fastify/formbody 插件来解析 x-www-form-urlencoded 主体。
通过npm安装：
npm i @fastify/formbodyES6
import fastify from 'fastify'
import formbody from '@fastify/formbody'
const app = fastify({ logger: false });
app.register(formbody)
ES5
const fastify = require('fastify')()
fastify.register(require('@fastify/formbody'))
