如何读取来自ionic的http请求的响应?我正在用ionic创建一个登录页面,并且试图从json对象中的php代码获取响应。来自后端的响应是我无法用离子捕捉到的。
.ts代码
this.http.post("http://localhost:83/api/v2/signin.php", JSON.stringify(this.credentials))
.subscribe(data => {
this.data = data;
console.log(this.data);
if(data.response=="success"){
let toast = this.toastCtrl.create({
message: 'Login was successfully',
duration: 3000,
position: 'top',
cssClass: 'dark-trans',
closeButtonText: 'OK',
showCloseButton: true
});
toast.present();
this.navCtrl.setRoot(HomePage);
this.storage.set("session",response);
this.global.session=response;
}else{
this.global.loginState="login";
let alert = this.alertCtrl.create({
subTitle: data.response,
buttons: ['OK']
});
alert.present();
}
登录失败时,控制台中将显示以下内容
Response {_body: "{"response":"Invalid login details entered"}"
成功,我有
Object { _body: "{\"response\":\"success\",
\"data\":{\"id\":\"4\",\"name\":\"Eli James\",
\"email\":\"eli_james@gmail.com\"}}",
status: 200, ok: true, statusText: "OK",
我的php代码是这样的:
if($row['email']==$email AND
$row['status']=='1'){
$response=array(
"response"=>"success",
"data"=>array(
"id"=>$row['id'],
"name"=>$row['name'],
"email"=>$row['email']
)
);
}else{
$response=array("response"=>"Invalid login details entered");
}
echo json_encode($response);

您将从后端获得string
作为响应正文。您将必须将正文解析为JSON,然后使用它。
只需将行从this.data = data;
更改为this.data = JSON.parse(data)
。
或this.data = JSON.parse(data._data);

使用post()方法的watch选项告诉HttpClient您想要完整的响应:
this.http.post(“ http:// localhost:83 / api / v2 / signin.php”,JSON.stringify(this.credentials),{观察:“响应”) .subscribe(fullResponse => { .......
现在,httpClient返回的是HttpResponse类型的Observable,而不仅仅是正文中包含的JSON数据。
