Angular 6-httpClient发布XML文件,angular,typescript,angular6,Angular,Typescript,Angular6,我正在使用Angular 6 httpClient，并在服务中包含以下代码： import { Injectable } from '@angular/core'; import { HttpClient, HttpHeaders } from '@angular/common/http'; const httpOptions = { headers: new HttpHeaders({ 'Content-Type': 'text/xml' }) }; @Injectable({ p

我正在使用Angular 6 httpClient，并在服务中包含以下代码：

import { Injectable } from '@angular/core';
import { HttpClient, HttpHeaders } from '@angular/common/http';

const httpOptions = {
  headers: new HttpHeaders({ 'Content-Type': 'text/xml' })
};

@Injectable({
  providedIn: 'root'
})
export class ApiService {

  constructor(private http: HttpClient) { }

  post() {
      const postedData = { userid: 1, title: 'title here', body: 'body text' };
      return this.http.post('this url here', postedData, httpOptions).subscribe(result => {
        console.log(result);
      }, error => console.log('There was an error: '));
  }

}

我的问题是：我想发布一个xml文件，那么如何修改此代码来实现这一点呢？

您想发布xml数据吗？您需要一个“内容类型”Http头

如果还希望接收XML，则响应类型的选项有json、text、blob和arraybuffer。XML不是一个选项，因此您要求将其作为纯文本，但（取决于您的API服务器）希望将接受类型“application/XML”和响应类型设置为“text”

post() {
  // Set your HttpHeaders to ask for XML.
  const httpOptions = {
    headers: new HttpHeaders({
      'Content-Type':  'application/xml', //<- To SEND XML
      'Accept':  'application/xml',       //<- To ask for XML
      'Response-Type': 'text'             //<- b/c Angular understands text
    })
  };
  const postedData = `
    <userid>1</userid>
    <title>title here</title>
    <body>body text</body>`;

  return this.http.post('this url here', postedData, httpOptions)
    .subscribe(
      result => { 
        console.log(result);  //<- XML response is in here *as plain text*
      }, 
      error => console.log('There was an error: ', error));
  }

post（）{
//设置HttpHeader以请求XML。
常量httpOptions={
标题：新的HttpHeaders({
“Content-Type”：“application/xml”，//只需将postedData
更改为您的xml字符串添加“Content-Type”标题和可选的“accept”const-headers=new-HttpHeaders（）；headers=headers.append（'Content-Type'：'text/xml'）；headers=headers.append（'accept'，'text/xml'））
然后将有效负载作为字符串发送。它的响应类型为：“text”作为“json”，并且应该超出1级，在标题之后：{…}。请参阅
