[英]fetch API POST request response
I am trying to get output from the post request once the form has been submitted but I get a promise response rather than the actual data when posting the form 表单提交后,我试图从发布请求中获取输出,但是发布表单时我得到了一个Promise响应而不是实际数据
fetch('localhost/clients', {
method: 'post',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json',
},
body: JSON.stringify(formData)
}).then(response => {
console.info('Sending Message ...')
console.info(response.json())
}).catch (error => {
console.log(error)
})
The data gets passed to the backend however I want to return the data thats been outputted by the API server. 数据被传递到后端,但是我想返回API服务器输出的数据。
response.json()
returns a Promise. response.json()
返回一个Promise。 You need to use it like below. 您需要像下面一样使用它。
fetch('localhost/clients', {
method: 'post',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json',
},
body: JSON.stringify(formData)
}).then(response => {
return response.json();
}).then(jsonResponse => {
console.log(jsonResponse);
}).catch (error => {
console.log(error)
})
