Android OkHttp Retrofit Token过期重

2017-09-13  本文已影响0人  小尤学习

遇到问题:

请求接口时遇到token过期重新获取token之后,不会再次请求当前接口。

解决办法:

在 OkHttpManager 这个类 里面 直接把 30001 和30002 拦截 重新获取接口 在重新请求一遍方法 虽然是这么简单,但是走了好多弯路,所以几下笔记,避免更多小伙伴踩坑

参考:

遇到的坑

报java.lang.IllegalStateException: closed,java.lang.IllegalStateException: closed,原因为OkHttp请求回调中response.body().string()只能有效调用一次

解决办法

     @Override
    public Response intercept(Chain chain) throws IOException
    {
        Request request = chain.request();
        logForRequest(request);
        Response response = chain.proceed(request);
       MediaType mediaType = response.body().contentType();
        String content= response.body().string();
        Log.e("tag", content);
        return response.newBuilder()
                .body(ResponseBody.create(mediaType, string))
                .build();
      // return logForResponse(response);

贴出代码部分
