问题描述
我使用angular 2代码发送了Azure Https POST请求。
I had sent the Azure Https POST request using angular 2 code.
vendordata(){
let input = {
VendorName: this.vname,
Address: this.add,
store: this.opt
};
let headers = new Headers();
headers.append('Content-Type', 'application/json');
this.http.post('https://dxxxxxxxxxxx', input, {headers: headers })
.subscribe(data => {
this.value = data;
console.log(this.value);
});
}
并收到以下错误:
错误:预检的响应包含无效的HTTP状态代码400
Error: Response for preflight has invalid HTTP status code 400
推荐答案
我用angular 4测试了你的代码并且它可以工作。
I tested your code with angular 4 and it works.
import { Component, OnInit } from '@angular/core';
import { Http, Headers } from '@angular/http';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
title = 'app';
constructor(private http: Http) {}
ngOnInit(): void {
const functionURI = 'https://<functionname>.azurewebsites.net/api/HttpTriggerJS1?code=<code>';
let input = {
name: "Azure",
};
let headers = new Headers();
headers.append('Content-Type', 'application/json');
this.http.post(functionURI, input, { headers: headers } ).subscribe(data => {
console.log(data);
});
}
}
这是我使用Javascript的简单HTTP触发函数:
Here is my simple HTTP trigger function using Javascript:
module.exports = function (context, req) {
context.log('JavaScript HTTP trigger function processed a request.');
if (req.query.name || (req.body && req.body.name)) {
context.res = {
// status: 200, /* Defaults to 200 */
body: "Hello " + (req.query.name || req.body.name)
};
} else {
context.res = {
status: 400,
body: "Please pass a name on the query string or in the request body"
};
}
context.done();
};
