Android获取Cookies,持久化PHPSESSID (OkHttp ;HttpClient ;Afinal)

公司后台是用PHP实现的,为了安全需要在每次请求头传过去PHPSESSID进行验证

.addHeader("Cookie", "PHPSESSID="+ToolsUser.getPhpsessid())

之前项目使用的afinal的FinalHttp模块来请求数据
https://github.com/yangfuhai/afinal
这个本质上是封装的httpclient,所以获取方法和httpclient类似

AjaxParams params = new AjaxParams();
params.put("x", "xxx");
params.put("xx", "xx");
new FinalHttp().get("url", params, new AjaxCallBack<String>() {
@Override
public void onSuccess(String t) {
super.onSuccess(t);
DefaultHttpClient dh = (DefaultHttpClient) http.getHttpClient();
CookieStore cookieStore = dh.getCookieStore();
List<Cookie> cookies = cookieStore.getCookies();
for (int i = 0, len = cookies.size(); i < len; i++) {
if ("PHPSESSID".equals(cookies.get(i).getName())) {
String phpsessid = cookies.get(i).getValue();
}
}
});
}

之前一直没找到方法,直到在某个地方看到HttpClient获取cookies的方法,
于是试着获取FinalHttp的DefaultHttpClient对象,这样就可以了.
其他获取cookies可以参考这 https://github.com/fantouch/hack10086/commit/0a8d77fdaef1a1f71d579f00366b3e4f818e90a6 在第一次请求时获取到的PHPSESSID保存,然后在以后每一次请求时

new FinalHttp().addHeader("Cookie", "PHPSESSID=" + phpsessid)

这样就能保存用户的登录状态了.
后来换到Android Studio 升级了SDK,返现httpclient已经成过时的方法了.....
网络请求换成OkHttp
网上找了不少保持cookies的方法,很坑,都是抄来抄去的文章,内容雷同,而且,基本都用不上...

new Thread(new Runnable() {
@Override
public void run() {
try {
String t = run1("url?x=xxx&xx=xx");
} catch (IOException e) {
e.printStackTrace();
}
}
}).start();

private String run1(String url) throws IOException {
Request request = new Request.Builder().url(url).build();
Response response = client.newCall(request).execute();
String string = response.body().string();
return string;
}

private OkHttpClient client = new OkHttpClient.Builder().cookieJar(new CookieJar() {

private final HashMap<HttpUrl, List<Cookie>> cookieStore = new HashMap<>();

@Override
public void saveFromResponse(HttpUrl url, List<Cookie> cookies) {
if (cookies != null) {
for (int i = 0, len = cookies.size(); i < len; i++) {
if ("PHPSESSID".equals(cookies.get(i).name())) {
String phpsessid = cookies.get(i).value();
}
}
}
cookieStore.put(url, cookies);
}

@Override
public List<Cookie> loadForRequest(HttpUrl url) {
List<Cookie> cookies = cookieStore.get(url);
return cookies != null ? cookies : new ArrayList<Cookie>();
}
}).build();

忘了上面那些方法在哪看到的了,感谢.
这样获取之后,也是在每次请求时

.addHeader("Cookie", "PHPSESSID="+phpsessid)

记录一下,下回有用的别的网络请求框架再补充进去
