如何在Retrofit请求里添加Cookie

你可以自定义一个RequestIntercaptor:

String cookieKey = ...

String cookieValue = ...

RestAdapter adapter = new RestAdapter.Builder()

.setRequestInterceptor(new RequestInterceptor() {

@Override

public void intercept(RequestFacade request) {

// assuming `cookieKey` and `cookieValue` are not null

request.addHeader("Cookie", cookieKey + "=" + cookieValue)

}

})

.setServer("http://...")

.build()

YourService service = adapter.create(YourService.class)

从服务器读取cookies再交给cookie manager管理：

OkHttpClient client = new OkHttpClient()

CustomCookieManager manager = new CustomCookieManager()

client.setCookieHandler(manager)

RestAdapter adapter = new RestAdapter.Builder()

.setClient(new OkClient(client))

...

.build()

CustomeCookieManager如下:

public class CustomCookieManager extends CookieManager {

// The cookie key we're interested in.

private final String SESSION_KEY = "session-key"

/**

* Creates a new instance of this cookie manager accepting all cookies.

*/

public CustomCookieManager() {

super.setCookiePolicy(CookiePolicy.ACCEPT_ALL)

}

@Override

public void put(URI uri, Map<String, List<String>>responseHeaders) throws IOException {

super.put(uri, responseHeaders)

if (responseHeaders == null || responseHeaders.get(Constants.SET_COOKIE_KEY) == null) {

// No cookies in this response, simply return from this method.

return

}

// Yes, we've found cookies, inspect them for the key we're looking for.

for (String possibleSessionCookieValues : responseHeaders.get(Constants.SET_COOKIE_KEY)) {

if (possibleSessionCookieValues != null) {

for (String possibleSessionCookie : possibleSessionCookieValues.split("")) {

if (possibleSessionCookie.startsWith(SESSION_KEY) &&possibleSessionCookie.contains("=")) {

// We can safely get the index 1 of the array: we know it contains

// a '=' meaning it has at least 2 values after splitting.

String session = possibleSessionCookie.split("=")[1]

// store `session` somewhere

return

}

}

}

}

}

}

Cookie一般用于后台和客户端数据访问的有效保证，由服务端创建，客户端保存，客户端访问时将Cookie保存在请求数据header里面，服务端收到访问请求后，解析出header的库，对本次请求进行有效的验证

移动端网络库一般都是用Retrofit库，Retrofit是对Okhttp的一次很完美的封装，并且可以自定义Okhttp，我们这里使用的方法就是利用拦截器，拦截每一次请求与访问，解析收到的数据，拿到header里面的Cookie，在把Cookie封装到每一帧的请求里面去

//第四步 Retrofit 初始化中加入 client 配置：

跟方法一样的,不同写法。
