我试图用头找重定向URL,所以我用Google搜索了一圈,发现了几个例子:获取使用链接重定向后的HTTPClient
Header[] arr = httpResponse.getHeaders("Location");
for (Header head : arr){
String whatever = arr.getValue();
}
和
HttpPost request1 = new HttpPost("https://hrlink.healthnet.com/");
HttpResponse response1 = httpclient.execute(request1);
// expect a 302 response.
if (response1.getStatusLine().getStatusCode() == 302) {
String redirectURL = response1.getFirstHeader("Location").getValue();
// no auto-redirecting at client side, need manual send the request.
HttpGet request2 = new HttpGet(redirectURL);
HttpResponse response2 = httpclient.execute(request2);
... ...
}
他们得到从头部的“位置”,但是我不能从我的版本拉出HttpResponseMessage的“位置”,我试着在这里和那里移动东西,但它不包含接受参数的方法,我怎么能够得到使用httpClient的重定向网址?
var client = new HttpClient();
var pairs = new List<KeyValuePair<string, string>>
{
new KeyValuePair<string, string>("username", "---"),
new KeyValuePair<string, string>("password", "---")
};
var content = new FormUrlEncodedContent(pairs);
var response = client.PostAsync(uri, content).Result;
HttpHeaders headerlist = response.Headers;
foreach (var header in headerlist)
{
//Red line on header("Location")
label1.Text += header("Location") + "\n";
}
设置AllowAutoRedirect为false:https://msdn.microsoft.com/en-us/library/system .net.httpwebrequest.allowautoredirect(v = vs.110).aspx然后你可以找到“位置” – 2016-07-22 09:03:23
@x ...我如何从HttpWebResponse获取“位置”? –
