React Native fetch()无法正常工作 [英] React Native fetch() not working android
本文介绍了React Native fetch()无法正常工作的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在尝试调用fetch()
函数.
它在iOS上工作正常,但在Android上不工作.
It works fine on iOS but not working on Android.
fetch('https://admin.leanpoint.com/Api/User/Login?user=srinu@mainpoint.dk', {
method: 'POST',
headers: {
'Authorization': 'Basic c3JpbnVAbWFpbnBvaW50LmRrOnNhaWJhYmE='
},
})
.then((res) => {
res.json().then((json) => {
alert(JSON.stringify(json))
})
})
.catch((err) => {
alert(JSON.stringify(err))
})
在iOS上,它输入.then()
,但是在Android上,它输入.catch()
,而err
是{}
.
On iOS, it enters .then()
but on Android it enters .catch()
and err
is {}
.
它在模拟器和真实设备上也不起作用.
It is not working on Emulator and real device as well.

使用Axios的错误日志
Error log using Axios
当我使用fetch()
时,它会以{}进入.catch()
.
When I used fetch()
it enters .catch()
with {}.
我尝试使用Axios
如下.
axios.post('https://admin.leanpoint.com/Api/User/Login?user=srinu@mainpoint.dk', null, {
headers: {
'Authorization': 'Basic c3JpbnVAbWFpbnBvaW50LmRrOnNhaWJhYmE='
},
timeout: 2000
})
.then((res) => {
console.log(res.data)
})
.catch((err) => {
console.log(err)
})
它返回如下错误.
