关于java：无法获取OkHttp \\的response.body.toString()返回字符串

Can't get OkHttp's response.body.toString() to return a string

我正在尝试使用OkHttp获取一些json数据，无法弄清楚为什么当我尝试记录response.body().toString()时得到的是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);

我不知道我在做什么错。如何获取响应字符串？

相关讨论

您已使用.string()功能在System.out.println()中打印响应。但是最后在Log.i()中，您正在使用.toString()。

因此，请在响应正文上使用.string()进行打印并获取您请求的响应，例如：

1	response.body().string();

注意：

.toString()：这将以字符串格式返回对象。

.string()：这将返回您的响应。

我认为这可以解决您的问题...对。

以防万一有人碰到和我一样的怪异事物。我在调试模式下的开发过程中运行代码，显然是从OKHttp 2.4

开始

..the response body is a one-shot value that may be consumed only once

因此，在调试时，检查员会调用"幕后"，并且主体始终为空。参见：https://square.github.io/okhttp/3.x/okhttp/okhttp3/ResponseBody.html

response.body,.string()只能使用一次。
请按以下方式使用：

1 2	String responseBodyString = response.body.string(); use the responseBodyString as needed in your application.

以下是我修改过的CurlInterceptor。在使用旧的Response之后，请检查在我要重新创建Response对象的拦截函数的末尾。

var responseBodyString = responseBody?.string()

response = response.newBuilder()
.body(
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("\
","\\\
")}'"
}

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 -> \
$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){}
}
}

使用字符串后重新创建响应对象

val responseBodyString = response.body()!!。string()

响应= response.newBuilder()
.body(ResponseBody.create(responseBody？.contentType()，responseBodyString.toByteArray()))
.build()

鉴于在大文件的情况下响应可能会产生OutOfMemoryError，您可以改为用字节数"窥视"正文并调用string()方法。

请注意，这会消耗身体。

response.peekBody(500).string());

尝试像这样更改它，例如：
