Question

使一个小型玩具应用发送API请求，响应始终是乱码。我使用Postman，PHP和Javascript尝试了完全相同的请求，都成功返回了有效的json字符串。

    OkHttpClient client = new OkHttpClient();

    MediaType mediaType = MediaType.parse("application/json;charset=UTF-8");
    RequestBody body = RequestBody.create(mediaType, "{\"researchConductType\":" + researchConductType +",\"skip\":" + skip + ",\"limit\":" + limit + "}");
    Request request = new Request.Builder()
            .url("https://app.respondent.io/projects/search")
            .post(body)
            .addHeader("Accept", "application/json, text/plain, */*")
            .addHeader("Origin", "https://app.respondent.io")
            .addHeader("X-Requested-With", "XMLHttpRequest")
            .addHeader("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.81 Safari/537.36")
            .addHeader("Content-Type", "application/json;charset=UTF-8")
            .addHeader("Referer", "https://app.respondent.io/projects/browse")
            .addHeader("Accept-Encoding", "gzip, deflate, br")
            .addHeader("Accept-Language", "en-US,en;q=0.9")
            .addHeader("Cookie", "ajs_user_id=null; ajs_group_id=null; consent=true")
            .addHeader("Cache-Control", "no-cache")
            .addHeader("Postman-Token", "8b10d40e-bd7f-4fd5-85cc-1381776ef549")
            .build();

    Response response = client.newCall(request).execute();
    Log.d("HTTPResult", "ResponseCode: " + String.valueOf(response.code()));
    return response.body().string();

我已经使用第三方HTTP请求捕获程序进行了验证，该应用程序和Postman的请求标头和正文都是相同的。

返回的结果字符串是这个
