Question

当我在节点中运行以下命令时：

request({
  "method": "POST",
  url: "http://localhost:8044/aut",
  headers: {'Content-Type': 'application/json'},
  body: JSON.stringify({secret: "danzellovestodance"})
}, function (error, response, body) {
  if (!error && response.statusCode == 200) {
    console.log("test"); console.log(response.body);
  }
});

我得到以下输出

test
{ core: { 'test name': { disabled: false, flaky: false, bug: true } } }

如何静默调试输出？我只想得到：

test
    { core: { 'test name': { disabled: false, flaky: false, bug: true  } }

Answer 1

在交互模式下使用Node.js时（通过调用glReadPixels），最后一个语句的评估结果会自动打印到控制台：

node

在您的情况下，它是表示请求的对象。如果将该代码移动到JavaScript源文件并运行它（“node file.js”），则不再出现该输出。出于实验目的，假设您确实希望在交互模式下使用Node.js，只需使该语句返回其他内容即可。这方面有多种方法。您可以在代码末尾附加一个较短的值：

> 2+2;
4
> new Object();
{}
> 2+2; 0
0

或将结果放在变量中：

request({
  "method": "POST",
  url: "http://localhost:8044/aut",
  headers: {'Content-Type': 'application/json'},
  body: JSON.stringify({secret: "danzellovestodance"})
}, function (error, response, body) {
  if (!error && response.statusCode == 200) {
    console.log("test"); console.log(response.body);
  }
}); 0 // will print 0, much cleaner

Answer 2

尝试：

var a= http.request({
 "method": "POST",
  url: "http://localhost:8044/aut",
  headers: {'Content-Type': 'application/json'},
  body: JSON.stringify({secret: "danzellovestodance"})
}, function (error, response, body) {
    if (!error && response.statusCode == 200) {
      console.log("test"); console.log(response.body);
   }
});
