如何使用OkHttp发布表单时，我使用cookie登录到网络？

我想提交一个表单，当我使用cookie登录到网络，但它似乎不工作，如何使它？（第一次尝试获取cookie，它工作，然后我尝试使用cookie再次登录并发布一些multipart/form-data，这一次不起作用，但响应代码是：200 OK，有什么问题？）如何使用OkHttp发布表单时，我使用cookie登录到网络？

你可以请张贴一些你已经试过的代码吗？ – ib11

我的意思是，点击你问题下面的[编辑]（http://stackoverflow.com/posts/37204339/edit）链接，并将代码添加到问题中，以便人们可以看到你到目前为止所尝试的内容。我为你做，所以你可以看到我的意思。 – ib11

你不想手动抓取这样的cookie。我强烈建议使用cookieJar。

/* 
* Creates a new client from the global client with 
* a stateful cookie jar. This is useful when you need 
* to access password protected sites. 
*/ 
public static OkHttpClient newClientWithCookieJar() { 
    CookieManager cookieManager = new CookieManager(); 
    cookieManager.setCookiePolicy(CookiePolicy.ACCEPT_ALL); 
    JavaNetCookieJar cookieJar = new JavaNetCookieJar(cookieManager); 
    return client.newBuilder().cookieJar(cookieJar).build(); 
}

只要您使用相同的客户端，它会自动解析cookie并将它们添加到每个请求中。
