我收到此错误
java.io.IOException: Content-Length and stream length disagree
在这行代码return response.body().bytes();
这是完整代码
编辑:在一些谷歌之后,错误的原因来自okhttp lib
if (contentLength != -1L && contentLength != bytes.size.toLong()) {
throw IOException(
"Content-Length ($contentLength) and stream length (${bytes.size}) disagree")
}
但如何解决?

这是完整的代码:

String myJSON;
JSONArray peoples = null;
InputStream inputStream = null;
@Override
protected byte[] doInBackground(Void... params) {
Log.d("e", "dddddddddd");
Log.d("e", Fetch_URL);
Request.Builder builder = new Request.Builder();
builder.url(Fetch_URL);
Request request = builder.build();
String result = null;
try {
Response response = httpClient.newCall(request).execute();
// int statusCode = response.getStatusLine().getStatusCode();
int statusCode =200;
// HttpEntity entity = response.body().byteStream();

return response.body().bytes();
}
else
{

}
} catch (Exception e) {

答案 0 :(得分:11)
抛出异常,因为您已调用InputStream inputStream = response.body().byteStream();
,然后再次调用response.body().bytes();
。
如果您要返回,则可以使用inputStream
或return result.getBytes();
中的返回字节数组。
从 inputStream 到 bytes ,请参阅以下内容:
public byte[] getBytesFromInputStream(InputStream inputStream) throws IOException {
try {
byte[] buffer = new byte[8192];
int bytesRead;
ByteArrayOutputStream output = new ByteArrayOutputStream();
while ((bytesRead = inputStream.read(buffer)) != -1) {
output.write(buffer, 0, bytesRead);
}
return output.toByteArray();
} catch (OutOfMemoryError error) {
return null;
}
}

如果您在ResponseBody.class
进行调试,则会看到以下屏幕截图:
