Question

我试图通过loopj的AsyncHttpClient从facebook图形API获得响应，但我遇到了编码问题。

https://graph.facebook.com/v2.1/Google?fields=posts.limit(15){message,object_id,type,updated_time},name,picture&access_token=########|########

当我将此网址传递给get（）时，我得到IllegalArgumentException：

 Illegal character in query at index 82: https://graph.facebook.com/v2.1/Google?fields=posts.limit(15){message,object_id,type,updated_time},name,picture&access_token=########|########
    java.lang.IllegalArgumentException: Illegal character in query at index 82: ttps://graph.facebook.com/v2.1/Google?fields=posts.limit(15){message,object_id,type,updated_time},name,picture&access_token=########|########

我尝试通过setURLEncodingEnabled()将URL编码设置为true和false，但它提供了相同的异常。还尝试过URLEncoder类，但没有运气。

我通过将URL的部分传递给URI的构造函数来修复此问题：

URL url = new URL("the graph url");
URI uri = new URI(url.getProtocol(), url.getUserInfo(), url.getHost(), url.getPort(), url.getPath(), url.getQuery(), url.getRef());
url = uri.toURL();
return url.toString();

使用loopj的AsyncHttpClient编码facebook图
