Retrofit + OKHTTP POST在body中发送Json字符串，服务器转义后解析失败

举个例子:
post在body中发送这个字符串 {"imei":"860475034"} ， 服务器会解析成 {\"imei\":\"860475034\"}

报错如下:

{"status":500,"message":"JSON parse error: Cannot construct instance of `java.util.LinkedHashMap` (although at least one Creator exists): no String-argument constructor/factory method to deserialize from String value ('{\"imei\":\"860475034\"}'); nested exception is com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot construct instance of `java.util.LinkedHashMap` (although at least one Creator exists): no String-argument constructor/factory method to deserialize from String value ('{\"imei\":\"860475034\"}')\n at [Source: (PushbackInputStream); line: 1, column: 1]"}

各种尝试后如下解决，在Retrofit 初始化时加入 ScalarsConverterFactory 并且对 GsonConverterFactory初始化进行修改，具体代码如下:

Retrofit.Builder()
            .baseUrl(NetUrl.BASE_URL)
            .addConverterFactory(ScalarsConverterFactory.create()) // 加入这一行
            .addConverterFactory(
                GsonConverterFactory.create(
                    GsonBuilder().disableHtmlEscaping().create() // 加入这一行
                )
            )  
            .client(okHttpClient)
            .build()

gradle文件，版本自己修改:

implementation 'com.squareup.retrofit2:converter-scalars:2.3.0'
implementation 'com.squareup.retrofit2:converter-gson:2.9.0'

搞定，么么哒~~
