Angular2:当发布到API时，总是得到一个400 bad request错误，但当使用RestClient时，我得到一个200 Ok错误

Question

我正忙于一个小的web应用程序，我正试图使用RestService向一个API发布，但却一直收到一个400坏的请求。当我使用失眠Rest客户端做完全相同的帖子时，我会得到200分...你知道我做错了什么吗/我可以看什么来发现发生了什么吗？

更新：原来问题是一个不正确的头，仍然有一个未解决的错误，我正在尝试添加正确的头...此处为问题继续链接

import { Component, OnInit } from '@angular/core';
import { FormBuilder, FormGroup, Validators } from '@angular/forms';

import { RestService } from '../../services/rest.service';

import { StockTakeModel } from '../../models/stock-take.model';

@Component({
  selector: 'stock-take',
  templateUrl: './stock-take.component.html',
  styleUrls: ['./stock-take.component.css']
})
export class StockTakeComponent implements OnInit {
    stockTakeForm: FormGroup;
    stockTakeModel: StockTakeModel;

  constructor(private fb: FormBuilder, private restService: RestService) { 
    this.stockTakeForm = fb.group({
        'SheetNo':['', Validators.required],
        'BinNo':['', Validators.required],
        'BarCode':['', Validators.required],
        'Quantity':['', Validators.required]
    });
    }

    doStockTake(val: any) {
        //console.log("val:" + JSON.stringify(val));
        //this.stockTakeModel = new StockTakeModel(0, 0, val[Object.keys(val)[2] '', val[Object.keys(val)[0]], val[Object.keys(val)[1]], val[Object.keys(val)[3]], 0);
        this.stockTakeModel = val;
    this.stockTakeModel.StockTakeID = '0';
    this.stockTakeModel.IDKey = '0';    
    this.stockTakeModel.ProductCode = '';
    this.stockTakeModel.PackSize = '0';
    console.log(this.stockTakeModel);
    console.log(JSON.stringify(this.stockTakeModel));
    this.submitStockTake(this.stockTakeModel);
    }

  submitStockTake(stockTakeModel: StockTakeModel) {
      //console.log(stockTakeModel);

    this.restService.postStockTake(stockTakeModel)
    .subscribe(
    (res) => {
        console.log(res);
    },
    (res) => {
        console.log("failure: " + res);
    }
    );
    this.stockTakeForm.reset();
  }

  ngOnInit() {

  }

}

rest.service.ts中的submitStockTake函数：

postStockTake(stockTakeModel: StockTakeModel) : Observable<Response> {
      console.log(JSON.stringify(stockTakeModel));

        return this.http.post(this.API_URL + "StockTake/AddToStockTake", JSON.stringify(stockTakeModel), this.headers)
        .map((res: Response) => res.json())
        .catch((error: any) => Observable.throw(error.json().error || 'server error'));
  }

这表明您并不是以两种方式发布相同的内容--可能是不同的请求头？Perhpas运行RestClient的浏览器是否已通过身份验证？检查network选项卡中的实际请求，并检查URL、头、身份验证等--必须有所不同。
