缺少必需参数：在ionic2中访问google令牌时的grant_type
错误：-
{
"error" : "invalid_request","error_description" : "required parameter is missing: grant_type"
}
码
let creds=JSON.stringify({
'client_id':'251059024984-8113pdtb11gm8m4evdq59stlpvcab8cn.apps.googleusercontent.com','client_secret':'uVWZt_Vd5mMLXGQDo7lmAIUe','redirect_uri':'http://localhost/callback','grant_type':'authorization_code','code':data
});
var headers = new Headers();
headers.append('Content-Type','application/x-www-form-urlencoded');
console.log(data)
this.http.post('https://accounts.google.com/o/oauth2/token',creds,{headers: headers}).map(res => res.json()).subscribe(data => {
console.log(data)
},(error)=>{
console.log('error in',error);
})
当我检查邮递员的api工作完美
解决方法
let creds = 'client_id=251059024984-8113pdtb11gm8m4evdq59stlpvcab8cn.apps.googleusercontent.com'
+'&client_secret=uVWZt_Vd5mMLXGQDo7lmAIUe'
+'&redirect_uri=http://localhost/callback'
+'&grant_type=authorization_code'
+'&code=' + data
JSON.stringify()不是正确的格式
