Using variables in OkHttpClient

Question

I have been trying to send a POST request with some user data. The request seems incomplete. I need help with this line

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 + "\"}");

The phone is a variable which has a user number but its not showing at the endpoint

Answer 1

在您的示例中，您似乎在\“ phone \”之后缺少了一个额外的双引号：这使其无效json。您已经在电话号码的右侧（而不是左侧）使用了引号。

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"
}
