Angular 5和PHP不能使用POST方法将值发送到服务器脚本 [英] Angular 5 and PHP can't use the POST method to send a value to server scripts
问题描述
在Angular 5和PHP中使用post方法时遇到问题.
I am having a problem using post method in Angular 5 and PHP.
我在.ts
类中有此方法:
addPartners(partnerName)
{
let headers = new Headers();
headers.append('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8');
this.name = JSON.stringify(partnerName)
console.log("hi "+ this.name)
return this.http.post('http://aff.local/addPartner.php', this.name, {
observe: 'response',
responseType: 'json'
}).pipe(map(
res=>{
console.log(res)
}
))
}
我将在按钮的(click)
事件中调用它:
And I will call it on (click)
event of a button:
addPartner(){
this.email = this.subscribeForm.get('emailTxt').value;
//console.log(this.email)
this.api.addPartners(this.email).subscribe(
(data)=>{
console.log(data);
this.subscribeForm.reset();
},
(error)=>{
console.log(error)
}
);
}
PHP脚本为:
当我填充文本框并单击按钮时,发送的值为空.
When I fill the textbox and click on the button, the value sent is empty.
当我更改方法时,通过在url
中发送变量,它可以正常工作.
When I change the method, by sending the variable in the url
it work properly.
这是工作脚本.在api主类中:
Here is the working script. In the api main class:
addPartners(partnerName)
{
let headers = new Headers();
headers.append('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8');
this.name = JSON.stringify(partnerName)
console.log("hi "+ name)
return this.http.post('http://aff.local/addPartner.php?name='+ name, {
observe: 'response',
responseType: 'json'
}).pipe(map(
res=>{
console.log(res)
}
))
}
我刚刚将网址更改为:
http://aff.local/addPartner.php?name='+ name,
在php脚本中,我将使用$_REQUEST['name']
来获取它.
And in the php script I will get it using $_REQUEST['name']
.
我想要的是使用POST
方法,因为我需要从表单发送多个数据.
What I want is using the POST
method because I need to send multiple data from a form.
推荐答案
如果要使用JSON.stringify,则可以使用以下命令从服务器端获取参数:
if you want to use JSON.stringify so you can take params from the server side using :
$request_body = file_get_contents('php://input');
$data = json_decode($request_body);
或者如果我们只想使用$ _POST ['paramName']来获取数据,那么我们必须在您的客户端中使用以下内容:
or if we want to just take data using $_POST['paramName'] so we have to use the below in your client side:
let headerOptions = new HttpHeaders().set('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8');
let data = {name: partnerName};
let body = this.formatData(test);
并像这样格式化数据:
formatData(data) {
let returnData = '';
let count = 0;
for (let i in data) {
if (count == 0) {
returnData += i + '=' + data[i];
} else {
returnData += '&' + i + '=' + data[i];
}
count = count + 1;
}
return returnData;
}
