您好我想在获取POST请求后获取响应头。我尝试调试以查看response
内console.log(response)
内的内容。我可以从responseData
获得响应主体,但我不知道如何获得标题。我想得到头部和身体。请帮忙。感谢:)
以下是我所做的例子:
fetch(URL_REGISTER, {
method: 'POST',
body: formData
})
.then((response) => response.json())
.then((responseData) => {
if(responseData.success == 1){
this.setState({
message1: responseData.msg,
});
}
else{
this.setState({
message1: responseData.msg,
});
}
})
.done();
},

你可以这样做
fetchData() {
var URL_REGISTER = 'https://www.example.com';
fetch(URL_REGISTER, {method: 'POST',body: formData})
.then(
function(response) {
console.log(response.headers.get('Content-Type'));
console.log(response.headers.get('Date'));
console.log(response.status);
console.log(response.statusText);
console.log(response.type);
console.log(response.url);
if (response.status !== 200) {
console.log('Status Code: ' + response.status);
return;
}
// Examine the text in the response
response.json().then(function(data) {
console.log(data);
});
}
)
.catch(function(err) {
console.log('Fetch Error', err);
});
}

您可以从response.headers
fetch(URL_REGISTER, {
method: 'POST',
body: formData
})
.then((response) => {
console.log(response.headers); //Returns Headers{} object
}

您应该像(return response.json();
