当我尝试使用 axios 向我自己的 typeorm API 发出 post 请求时出现以下错误:
TypeError: Converting circular structure to JSON
--> starting at object with constructor 'ClientRequest'
| property 'socket' -> object with constructor 'Socket'
--- property '_httpMessage' closes the circle
at JSON.stringify (<anonymous>)
at stringify (C:\Users\Usuario\Documents\Manga-Api\Manga-Api\node_modules\express\lib\response.js:1123:12)

我尝试使用一些库来修复循环结构 JSON 并解析它,但都失败了:
const safeStringify = require('json-stringify-safe');
const CircularJSON = require('circular-json');
所有实体的关系都没有添加级联选项。
await axios.post(apiName+'/object', data, { headers: { Authorization: res.req.headers.authorization } }).then(response => { res.send(response); });
我想保留在我的数据库中的对象的数据示例:
data = {

如果我尝试通过 Postman 发布此 JSON,它可以正常工作。不是通过代码购买,可能是由于实体的循环问题
答案 0 :(得分:1)
正如@backtick 所说,我应该做 res.send(response.data) 而不是整个响应对象。谢谢
