获取 API POST 请求响应
我正在尝试在提交表单后从发布请求中获取输出，但在发布表单时我得到的是承诺响应而不是实际数据
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
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)
})
数据被传递到后端，但是我想返回 API 服务器输出的数据.
The data gets passed to the backend however I want to return the data thats been outputted by the API server.
推荐答案
response.json() 返回一个 Promise.你需要像下面这样使用它.
response.json() returns a Promise. You need to use it like below.
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)
})
