SSL handshake Android studio java problem for okhttp ok_get

Question

我在将 Json 数据放入我的应用程序中时遇到了问题。在获取操作时。我已经解决了开机自检的问题。我们有一个 ssl 证书，但似乎获取和发布的方式几乎没有什么不同。我想不通。所以如果人们能在这里给我帮助。我将不胜感激。

从编译中我得到一个错误：

该错误表示您正在调用 get 请求而不传递 HashMap。 我的建议是，如果你有一些需要正文的 URL，要么传递一个空的 HashMap。否则将其完全删除：

public static String Ok_Get(Context context,String url) {
String data = "";
OkHttpClient okHttpClient= MyApp.handleSSLHandshake();
FormBody.Builder builder = new FormBody.Builder();
builder.build();
Request request = new Request.Builder().url(url).build();

如果你仍然需要它，当你调用它时，请确保你包含HashMap：

Ok_Get(context, "your/url/string/here", Collections.<String, String>emptyMap())
