java - 在 OkHttpClient 中使用变量

Question

我一直在尝试发送带有一些用户数据的 POST 请求。该请求似乎不完整。我需要这条线的帮助

OkHttpClient client = new OkHttpClient();
MediaType mediaType = MediaType.parse("application/json");
StringEntity postingString = new StringEntity(gson.toJson(pj));
RequestBody body = RequestBody.create(mediaType, "{\n   \"url\":\"https://okirizuri.herokuapp.com/check\",\"phone\":"  + phone + "\"}");
Request request = new Request.Builder()
        .url("https://okirizuri.herokuapp.com/lipa")
        .post(body)
        .addHeader("content-type", "application/json")
        .addHeader("cache-control", "no-cache")
        .build();
 String phone = editText.getText().toString().trim();

RequestBody body = RequestBody.create(mediaType, "{\n   \"url\":\"https://okirizuri.herokuapp.com/check\",\"phone\":"  + phone + "\"}");

电话是一个变量，它有一个用户号码，但它没有在端点上显示

Answer 1

在您的示例中，您在\"phone\": 之后缺少一个额外的双引号:这使其无效 json。您在电话号码的右侧转义了引号，但在左侧转义了引号。

RequestBody body = RequestBody.create(mediaType, "{\n   \"url\":\"https://okirizuri.herokuapp.com/check\",\"phone\":"  + phone + "\"}");

JSON:

{
    "url": "https://okirizuri.herokuapp.com/check",
    "phone": 555-555-5555"
}

应该是:

RequestBody body = RequestBody.create(mediaType, "{\n   \"url\":\"https://okirizuri.herokuapp.com/check\",\"phone\":\""  + phone + "\"}");

JSON:

{
    "url": "https://okirizuri.herokuapp.com/check",
    "phone": "555-555-5555"
}
