Question

OkHttp版本：2.0.0

我通过Google Play收到了以下异常堆栈跟踪：

java.lang.IllegalStateException：无法流式传输请求体分块编码或已知内容长度！在 com.squareup.okhttp.internal.http.HttpTransport.createRequestBody（HttpTransport.java:68）在 com.squareup.okhttp.internal.http.HttpEngine.sendRequest（HttpEngine.java:254）在com.squareup.okhttp.Call.getResponse（Call.java:198）at com.squareup.okhttp.Call.access $ 200（Call.java:36）at com.squareup.okhttp.Call $ AsyncCall.execute（Call.java:143）at com.squareup.okhttp.internal.NamedRunnable.run（NamedRunnable.java:33）在 java.util.concurrent.ThreadPoolExecutor.runWorker（ThreadPoolExecutor.java:1112）在 java.util.concurrent.ThreadPoolExecutor中的$ Worker.run（ThreadPoolExecutor.java:587）在java.lang.Thread.run（Thread.java:848）

这正是提出请求的方式：

Request.Builder requestBuilder = new Request.Builder();
requestBuilder.addHeader("User-Agent", userAgent);
requestBuilder.addHeader("Accept", "application/hal+json");
requestBuilder.url(transformedURL);

RequestBody requestBody = body == null ? null : RequestBody.create(MediaType.parse("application/json"), gson.toJson(body));
requestBuilder.method(method, requestBody);

okHttpClient.newCall(requestBuilder.build()).enqueue(new com.squareup.okhttp.Callback() { ...

起初它似乎与this bug有关，但它已被修复。此外，我们在开发期间多次使用空体测试POST请求。
这个应用程序只执行GET和POST请求。

可能导致此错误的原因是什么？

Answer 1

您是如何创建HTTP请求的？如果您可以创建可重现的测试用例，请向OkHttp提交一个错误，我们将会修复。

Answer 2

以下代码抛出了这个异常：

包okhttp3.internal.http;

<强> Http1xStream.java

  @Override public Sink createRequestBody(Request request, long contentLength) throws IOException {
    if ("chunked".equalsIgnoreCase(request.header("Transfer-Encoding"))) {
      // Stream a request body of unknown length.
      return newChunkedSink();
    }

    if (contentLength != -1) {
      // Stream a request body of a known length.
      return newFixedLengthSink(contentLength);
    }

    throw new IllegalStateException(
        "Cannot stream a request body without chunked encoding or a known content length!");
  }

要解决此问题，我需要在我的请求中添加一个标头，可以像这样添加：.addHeader("Transfer-Encoding","chunked")：

OP的样本：

Request.Builder requestBuilder = new Request.Builder();
requestBuilder.addHeader("User-Agent", userAgent);
requestBuilder.addHeader("Accept", "application/hal+json");

<强> requestBuilder..addHeader("Transfer-Encoding","chunked")

requestBuilder.url(transformedURL);

2.0.0：IllegalStateException：无法在没有分块编码或已知内容长度的情况下流式传输请求主体
