Question

我有一个使用Node.js和Express.js的REST API。我正在使用Angular5应用程序来使用REST API。关于从Angular应用程序进行API调用，它是通过服务完成的，代码如下：

auth.service.ts：

login(email: string, password: string) {
    return this.http.post( environment.baseUrl + '/api/v1/login', JSON.stringify({ email: email, password: password }))
      .map((response: Response) => {
        let user = response.json();
        if (user && user.token) {
          localStorage.setItem('currentUser', JSON.stringify(user));
        }
      });
  }

在我的节点app.ts中，应用程序定义如下：

app.ts：

const app = express();
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));

app.use(function (req, res, next) {
  // Website you wish to allow to connect
  res.header('Access-Control-Allow-Origin', '*');
  // Request methods you wish to allow
  res.header('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
  // Request headers you wish to allow
  res.header('Access-Control-Allow-Headers', 'X-Requested-With,content-type,__setXHR_');
  // Set to true if you need the website to include cookies in the requests sent
  // to the API (e.g. in case you use sessions)
  res.header('Access-Control-Allow-Credentials', true);
  // Pass to next layer of middleware
  next();
});

如果你看看控制器，这里是代码：

login = (req, res) => {
    console.log(req.body);
    this.model.findOne({ email: req.body.email }, (err, user) => {
      if (!user) { return res.sendStatus(403); }
      user.comparePassword(req.body.password, (error, isMatch) => {
        if (!isMatch) { return res.sendStatus(403); }
        const token = jwt.sign({ user: user }, process.env.SECRET_TOKEN); // , { expiresIn: 10 } seconds
        res.status(200).json({ token: token });
      });
    });
  }

我收到403错误，以下是我的控制台上打印的内容：

[2] {}
[2] {}
[2] POST /api/v1/login 403 22.004 ms - 9

我几乎可以看到我的chrome调试器中发送了请求正文。

我在这里做错了什么？

实际上，我在帖子请求中使用了void spread(int v, int x, int y, int *t,int w, int *count){ //table of directions(Right,Down,Left,Up) int d[4][2] = {{1,0},{0,1},{-1,0},{0,-1}}; int i; t[y * w + x] = v; if(v == 0 && (x & 1) && (y & 1)) (*count)++; /*increments at every box which has value as zero with x odd and y also*/ //spread the value to all directions for(i = 0; i < 4; i++){ if(v < t[(y+d[i][1]) * w + x +d[i][0]]){ spread(v,x + d[i][0],y+d[i][1],t,w,count); } } } int *init(int m, int n){ //Initializing the maze int *t = NULL, mp = 2 * m +1, np = 2 * n + 1; int x,y,k,d; int count = 1; t = malloc(mp * np * sizeof *t); assert(t); for(y = k = 0; y < np ;++y){ for(x = 0; x < mp; ++x){ if((x & 1) && (y & 1)) t[y * mp + x] = k++; else t[y * mp + x] = -1; } } //Make a labyrinth randomly srand(time(NULL)); while(count < (m * n)){ if(myRand(2)){ // Up/Down separator do{ x = myRand(m) * 2 + 1; y = (myRand(n - 1) + 1) * 2; }while(t[(y - 1) * mp + x] == t[(y + 1) * mp + x]); /*Don't select the ones which are equal*/ d = t[(y - 1) * mp + x] - t[(y + 1) * mp + x]; //d selects the lowest one if(d > 0){ t[y * mp +x] = t[(y + 1) * mp + x]; spread(t[(y + 1) * mp +x],x,y-1,t,mp,&count); } else if(d < 0){ t[y * mp +x] = t[(y - 1) * mp + x]; spread(t[(y - 1) * mp +x],x,y+1,t,mp,&count); } } else{ //Right/Left separator do{ x = (myRand(m - 1) + 1) * 2; y = myRand(n) * 2 + 1; }while(t[y * mp + x - 1] == t[y * mp + x + 1]); d = t[y * mp + x - 1] - t[y * mp + x + 1]; if(d > 0){ t[y * mp +x] = t[y * mp + x + 1]; spread(t[y * mp + x + 1],x-1,y,t,mp,&count); } else if(d < 0){ t[y * mp +x] = t[y * mp +x - 1]; spread(t[y * mp + x - 1],x+1,y,t,mp,&count); } } } return t; } 。我不得不发送对象而不是JSON字符串。在删除它，它工作。
