IWI*_*IWI 1 http-headers angular angular-httpclient
Angular HttpHeaders responseType: 'text' 。给予Type 'string' is not assignable to type 'json'。错误。我知道响应不是 JSON。我不明白如何更改类型?我想获取该文本(HTML)并在之后用正则表达式解析它。
代码
const httpOptions = {
headers: new HttpHeaders({
accept: '*/*',
contentType: 'application/x-www-form-urlencoded',
}),
responseType: 'text',
};
post = this.httpClient.post(destinationUrl, httpBody, httpOptions);
post.subscribe(
(res) => {
console.log(res)
},
(error) => {
console.error('download error:', error)
},
() => {
console.log('Completed')
},
);

如您所见,响应类型是文本。由于我不明白的事情,我无法让它接受文本,因为它正在等待 json ...

我解决了这个问题,使 HTTPOptions 作为一个对象
let HTTPOptions:Object = {
headers: new HttpHeaders({
'Content-Type': 'application/json'
}),
responseType: 'text'
}
return this.http.post<any>(url, body, HTTPOptions ).pipe(
catchError(this.handleError)
);
