Flutter-处理POST请求中的状态码302
我试图post
在Flutter中发送带有DIO
包装的请求。
这是请求:
getSessionId() async { var csrf = await getCsrftoken();
var dio = new Dio(new Options(
baseUrl: "http://xxxxxxx/accounts/login/",
connectTimeout: 5000,
receiveTimeout: 100000,
// 5s
headers: {
'Cookie': "csrftoken=" + csrf
},
contentType: ContentType.JSON,
// Transform the response data to a String encoded with UTF8.
// The default value is [ResponseType.JSON].
responseType: ResponseType.PLAIN
));
var response;
response = await dio.post("http://xxxxxxx/accounts/login/",
data: {
"username": "xxxxx",
"password": "xxxxx",
"csrfmiddlewaretoken" : csrf
},
options: new Options(
contentType: ContentType.parse("application/x-www-form-urlencoded")),
);
print("StatusCode: ");
print(response.statusCode);
print("Response cookie: "); //THESE ARE NOT PRINTED
print(response.headers);
}
请求后,我得到:
E/flutter ( 4567): [ERROR:flutter/shell/common/shell.cc(181)] Dart Error: Unhandled exception: E/flutter ( 4567): DioError [DioErrorType.RESPONSE]: Http status error [302]
E/flutter ( 4567): #0 getSessionId (file:///C:/get_order/lib/main.dart:36:14)
E/flutter ( 4567): <asynchronous suspension>
从此请求中,我只需要获取sessionid
cookie,但是该函数会因未处理的异常而停止。
回答:
我这样解决了:
在请求中添加followRedirects: false
和validateStatus: (status) { return status <
500;}。像这样:
var response = await Dio().post("http://myurl", data: requestBody,
options: Options(
followRedirects: false,
validateStatus: (status) { return status < 500; }
),
);
这样,您就可以从302
彼此之间得到帮助headers
。
