我试图使用OkHttp获取一些json数据,并且无法弄清楚为什么当我尝试记录response.body().toString()
我得到的是Results:﹕ com.squareup.okhttp.Call$RealResponseBody@41c16aa8
try {
URL url = new URL(BaseUrl);
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url(url)
.header(/****/)
.build();
Call call = client.newCall(request);
Response response = call.execute();
**//for some reason this successfully prints out the response**
System.out.println("YEAH: " + response.body().string());
if(!response.isSuccessful()) {
Log.i("Response code", " " + response.code());
}
Log.i("Response code", response.code() + " ");
String results = response.body().toString();
Log.i("OkHTTP Results: ", results);
我不知道我在这里做错了什么。我如何获得响应字符串?

您已使用.string()
功能在System.out.println()
中打印回复。但最后在Log.i()
您正在使用.toString()
。
因此,请在回复正文上使用.string()
进行打印并获取您的请求回复,例如:
response.body().string();
注意:强>
.toString()
:以字符串格式返回您的对象。
.string()
:这会返回您的回复。
我认为这可以解决你的问题......对。

以防万一有人碰到和我一样奇怪的事情。我在开发期间以调试模式运行我的代码,显然是从OKHttp 2.4
开始..响应主体是一次性值,只能消耗一次
因此,在调试时,检查员会在“幕后”进行调用,并且正文始终为空。请参阅:https://square.github.io/okhttp/3.x/okhttp/okhttp3/ResponseBody.html

response.body,.string()
只能消耗一次。
请使用如下:
String responseBodyString = response.body.string();
use the responseBodyString as needed in your application.

以下是我修改过的CurlInterceptor。在使用完旧的Response后,请在我要在其中重新创建Response对象的拦截函数的末尾进行检查。
var responseBodyString = responseBody?.string()
response = response.newBuilder() 。身体( ResponseBody.create( responseBody?.contentType(), responseBodyString.toByteArray() ) ) .build()
class CurlInterceptor: Interceptor
{
var gson = GsonBuilder().setPrettyPrinting().create()
override fun intercept(chain: Interceptor.Chain): Response {
Timber.d(" **** ->>Request to server -> ****")
val request = chain.request()
var response = chain.proceed(request)
var curl = "curl -v -X ${request.method()}"
val headers = request.headers()
for ( i in 0..(headers.size() -1) ){
curl = "${curl} -H \"${headers.name(i)}: ${headers.value(i)}\""
}
val requestBody = request.body()
if (requestBody != null) {
val buffer = Buffer()
requestBody.writeTo(buffer)
var charset: Charset =
Charset.forName("UTF-8")
curl = "${curl} --data '${buffer.readString(charset).replace("\n", "\\n")}'"
}
Timber.d("$curl ${request.url()}")
Timber.d("response status code ${response.code()} message: ${response.message()}")
dumbHeaders(response)
var responseBody = response?.body()
if(responseBody != null )
{
var responseBodyString = responseBody?.string()
response = response.newBuilder()
.body(
ResponseBody.create(
responseBody?.contentType(),
responseBodyString.toByteArray()
)
)
.build()
responseBodyString = gson.toJson(responseBodyString)
Timber.d("response json -> \n $responseBodyString")
}
Timber.d(" **** << Response from server ****")
return response
}
fun dumbHeaders(response: Response) {
try {
if (response.headers() != null) {
for (headerName in response.headers().names()) {
for (headerValue in response.headers(headerName)) {
Timber.d("Header $headerName : $headerValue")
}
}
}
}
catch (ex: Exception){}
}
}

例如尝试更改它:
protected String doInBackground(String... params) {
try {
JSONObject root = new JSONObject();
JSONObject data = new JSONObject();
data.put("type", type);
data.put("message", message);
data.put("title", title);
data.put("image_url", imageUrl);
data.put("uid",uid);
data.put("id", id);
data.put("message_id", messageId);
data.put("display_name", displayName);
root.put("data", data);
root.put("registration_ids", new JSONArray(receipts));
RequestBody body = RequestBody.create(JSON, root.toString());
Request request = new Request.Builder()
.url(URL)
.post(body)
.addHeader("Authorization", "key=" + serverKey)
.build();
Response response = mClient.newCall(request).execute();
String result = response.body().string();
Log.d(TAG, "Result: " + result);
return result;
} catch (Exception ex) {
Log.e(TAG,"Exception -> "+ex.getMessage());
}
return null;
}

鉴于文件很大,响应可能会产生OutOfMemoryError
,因此您可以用字节数“窥视”正文并调用string()
方法。
请注意,这会消耗身体。
response.peekBody(500).string());

使用字符串后重新创建响应对象
val responseBodyString = response.body()!!。string()
response = response.newBuilder() .body(ResponseBody.create(responseBody?.contentType(),responseBodyString.toByteArray())) .build()
