Question

我正在创建一个简单的NodeJS服务器，该服务器将接收POST请求并执行一些业务逻辑

IEnumerator MyRoutine() {
    while (true) {
        if (conditionA || conditionB) {
            yield break; // stop stepping this
        }
        yield return null; // continue stepping next frame
    }
}

现在，当我用json对邮递员的示例POST请求进行测试时，我得到了错误var server = http.createServer(function(request, response) { if (request.method == 'POST') { var body = ''; request.on('data', function (data) { body += data; }); request.on('end', function () { try { var post = JSON.parse(body); deal_with_post_data(request,post); response.writeHead(200, {"Content-Type": "text/plain"}); response.end(); return; }catch (err){ response.writeHead(500, {"Content-Type": "text/plain"}); response.write("Bad Post Data. Is your data a proper JSON?\n"); response.end(); return; } }); } }); server.listen(3000); console.log("server started")，这实际上意味着它进入了Bad Post Data. Is your data a proper JSON?。

这是我尝试过的示例JSON

500 internal server error

并将POST请求发送到{ "glossary":"book" }

有人可以建议吗？

只需测试您的代码：

const http = require('http');

var server = http.createServer(function(request, response) {
if (request.method == 'POST') {
        var body = '';
        request.on('data', function (data) {
            body += data;
        });
        request.on('end', function () {
            try {
              var post = JSON.parse(body);
              // deal_with_post_data(request,post);
              console.log(post); // <--- here I just output the parsed JSON
              response.writeHead(200, {"Content-Type": "text/plain"});
              response.end();
              return;
            }catch (err){
              response.writeHead(500, {"Content-Type": "text/plain"});
              response.write("Bad Post Data.  Is your data a proper JSON?\n");
              response.end();
              return;
            }
        });
    }
});
server.listen(3000);
console.log("server started")

在Postman中，我使用给定的JSON（如raw发出了POST请求，并在控制台上记录了正确的JSON。因此提供的代码很好。问题可能出在deal_with_post_data函数（您在此处未显示）
