Caused by: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 39...

在使用Gson解析JSON数据时，报错：Caused by: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 3939

原因：传入的参数有问题；

while((len=inputStream.read(data))!=-1){
            outPutStream.write(data,0,len);
        }

错写成：

while((len=inputStream.read())!=-1){
            outPutStream.write(data,0,len);
        }

导致：

String jsonString=HttpUtils.getJsonContent(path);
            System.out.println("jsonString-->:"+jsonString.toString());
            Person person=GsonTools.getPerson(jsonString.trim(), Person.class);

上段GsonTools.getPerson中的jsonString参数有问题，从而引起报错，其实质是：传入的JSON字符串格式不对导致
