1.首先在app.module.ts的修改
import {
HttpClientModule}
from
'@angular/common/http';
imports 中引入
HttpClientModule
2.在providers中自己新建的https文件夹下的https.ts中
import {
Injectable }
from
'@angular/core';
import {
HttpClient,
HttpHeaders }
from
'@angular/common/http';
import {
Observable }
from
'rxjs/Observable';
import {
of }
from
'rxjs/observable/of';
import {
catchError,
map,
tap }
from
'rxjs/operators';
const
httpOptions = {
headers:
new
HttpHeaders({
'Content-Type'
:
'application/json;charset=UTF-8' })
};
@
Injectable()
export
class
HttpsProvider {
constructor(
public
http:
HttpClient
) {
console.
log(
'Hello HttpsProvider Provider');
}
addPost(){
let
hotMoviesUrl:
string =
"http:/访问项目的ip/myapp/login";
return
this.
http.
post(
hotMoviesUrl,
'{"user": "测试1"}',
httpOptions).
subscribe(
(
data)
=>{
console.
log(
data+
"success")
}
)
}
}
注意
1.发送时一定要json格式的数据{ “user” : "测试"}，可以写一个工具类
2.没有对异常进行处理，以后再优化，这只是一个最简单的请求
