JSON 输入的 Golang 大型响应意外结束
Golang large response unexpected end of JSON input
我正在向服务器发送请求并尝试解组 HTTP 响应。这很奇怪，但是有些响应 return 200 并且没有给出解组错误，而其中一些响应 return 200 并且给出了解组错误。
我的客户端代码如下：
func SendRequest(requestModel *model.Request) (*model.Response, error) {
responseModel := &dspModel.Response{}
byteData, err := json.Marshal(requestModel)
if err != nil {
zap.S().Errorf("Error marshalling request. Err: %v", err)
return nil, err
}
url := "xx"
request, _ := http.NewRequest(http.MethodPost, url, bytes.NewBuffer(byteData))
request.Close = true
client := &http.Client{}
response, err := client.Do(request)
if err, ok := err.(net.Error); ok && err.Timeout() {
zap.S().Error("Response timeout exceed")
return nil, errors.New("Response timeout exceed")
}
if err != nil || response == nil {
errorMessage := "not respond"
zap.S().Error(errorMessage)
return nil, errors.New(errorMessage)
}
defer response.Body.Close()
if response.StatusCode == http.StatusOK {
err = json.NewDecoder(response.Body).Decode(&responseModel)
if err != nil {
// Error occurred here!
errorMessage := "Request response decode error"
zap.S().Errorf("%v, Err: %v", errorMessage, err)
return nil, errors.New(errorMessage)
}
return response, nil
} else if response.StatusCode == http.StatusNoContent {
return nil, nil
} else {
bodyBytes, _ := ioutil.ReadAll(response.Body)
errorMessage := "not respond"
zap.S().Errorf("%v, StatusCode %v, Response: %v Request: %v", errorMessage,
response.StatusCode, string(bodyBytes), string(byteData))
return nil, errors.New(errorMessage)
}
}
我怀疑响应太长且字符不同。
响应看起来像：

可能不相关，但请求是并发的，我的测试用例仅基于一个并发请求。那么我该如何解决这个问题呢？
我试着在我这边实现你的代码，它给出了预期的输出。我试过的代码如下。

此外，在注释掉请求正文部分（因为我没有它）并稍微更改函数签名（SendRequest）之后，我使用了您正在使用的相同代码，如下所示.其他和上面给出的代码一样。
func SendRequest() (*Response, error) {
responseModel := &Response{}
// Commented off since the response body is not with me..
// byteData, err := json.Marshal(requestModel)
// if err != nil {
// zap.S().Errorf("Error marshalling request. Err: %v", err)
// return nil, err
// }
url := "http://localhost:8080/foo"
request, _ := http.NewRequest(http.MethodPost, url /*bytes.NewBuffer(byteData)*/, nil)
request.Close = true
client := &http.Client{}
response, err := client.Do(request)
if err, ok := err.(net.Error); ok && err.Timeout() {
log.Fatal("Response timeout exceed")
return nil, errors.New("Response timeout exceed")
}
if err != nil || response == nil {
errorMessage := "not respond"
log.Fatal(errorMessage)
return nil, errors.New(errorMessage)
}
defer response.Body.Close()
if response.StatusCode == http.StatusOK {
err = json.NewDecoder(response.Body).Decode(&responseModel)
if err != nil {
errorMessage := "Request response decode error"
log.Printf("%v, Err: %v", errorMessage, err)
return nil, errors.New(errorMessage)
}
return responseModel, nil
} else {
bodyBytes, _ := ioutil.ReadAll(response.Body)
errorMessage := "not respond"
log.Printf("%v, StatusCode %v, Response: %v\n", errorMessage, response.StatusCode, string(bodyBytes))
return nil, errors.New(errorMessage)
}
}
同样，我能够成功解组响应。
所以，在我看来，传入的响应是不正确的（可能是）。尝试打印传入数据并验证。
resBody, err := ioutil.ReadAll(response.Body)
if err != nil {
return nil, err
}
fmt.Printf("%s", resBody) //
我正在向服务器发送请求并尝试解组 HTTP 响应。这很奇怪，但是有些响应 return 200 并且没有给出解组错误，而其中一些响应 return 200 并且给出了解组错误。
我的客户端代码如下：
func SendRequest(requestModel *model.Request) (*model.Response, error) {
responseModel := &dspModel.Response{}
byteData, err := json.Marshal(requestModel)
if err != nil {
zap.S().Errorf("Error marshalling request. Err: %v", err)
return nil, err
}
url := "xx"
request, _ := http.NewRequest(http.MethodPost, url, bytes.NewBuffer(byteData))
request.Close = true
client := &http.Client{}
response, err := client.Do(request)
if err, ok := err.(net.Error); ok && err.Timeout() {
zap.S().Error("Response timeout exceed")
return nil, errors.New("Response timeout exceed")
}
if err != nil || response == nil {
errorMessage := "not respond"
zap.S().Error(errorMessage)
return nil, errors.New(errorMessage)
}
defer response.Body.Close()
if response.StatusCode == http.StatusOK {
err = json.NewDecoder(response.Body).Decode(&responseModel)
if err != nil {
// Error occurred here!
errorMessage := "Request response decode error"
zap.S().Errorf("%v, Err: %v", errorMessage, err)
return nil, errors.New(errorMessage)
}
return response, nil
} else if response.StatusCode == http.StatusNoContent {
return nil, nil
} else {
bodyBytes, _ := ioutil.ReadAll(response.Body)
errorMessage := "not respond"
zap.S().Errorf("%v, StatusCode %v, Response: %v Request: %v", errorMessage,
response.StatusCode, string(bodyBytes), string(byteData))
return nil, errors.New(errorMessage)
}
}
我怀疑响应太长且字符不同。 响应看起来像：

可能不相关，但请求是并发的，我的测试用例仅基于一个并发请求。那么我该如何解决这个问题呢？
我试着在我这边实现你的代码，它给出了预期的输出。我试过的代码如下。
注意：这不是确切问题的解决方案，因为我无法重现相同的问题。

此外，在注释掉请求正文部分（因为我没有它）并稍微更改函数签名（SendRequest）之后，我使用了您正在使用的相同代码，如下所示.其他和上面给出的代码一样。
func SendRequest() (*Response, error) {
responseModel := &Response{}
// Commented off since the response body is not with me..
// byteData, err := json.Marshal(requestModel)
// if err != nil {
// zap.S().Errorf("Error marshalling request. Err: %v", err)
// return nil, err
// }
url := "http://localhost:8080/foo"
request, _ := http.NewRequest(http.MethodPost, url /*bytes.NewBuffer(byteData)*/, nil)
request.Close = true
client := &http.Client{}
response, err := client.Do(request)
if err, ok := err.(net.Error); ok && err.Timeout() {
log.Fatal("Response timeout exceed")
return nil, errors.New("Response timeout exceed")
}
if err != nil || response == nil {
errorMessage := "not respond"
log.Fatal(errorMessage)
return nil, errors.New(errorMessage)
}
defer response.Body.Close()
if response.StatusCode == http.StatusOK {
err = json.NewDecoder(response.Body).Decode(&responseModel)
if err != nil {
errorMessage := "Request response decode error"
log.Printf("%v, Err: %v", errorMessage, err)
return nil, errors.New(errorMessage)
}
return responseModel, nil
} else {
bodyBytes, _ := ioutil.ReadAll(response.Body)
errorMessage := "not respond"
log.Printf("%v, StatusCode %v, Response: %v\n", errorMessage, response.StatusCode, string(bodyBytes))
return nil, errors.New(errorMessage)
}
}
同样，我能够成功解组响应。
所以，在我看来，传入的响应是不正确的（可能是）。尝试打印传入数据并验证。
resBody, err := ioutil.ReadAll(response.Body)
if err != nil {
return nil, err
}
fmt.Printf("%s", resBody) //
