高浪大响应 JSON 输入意外结束
我正在向服务器发送请求，并尝试取消对 HTTP 响应的封口。这很奇怪，但有些响应返回 200 并且没有给出非马歇尔错误，而其中一些回复返回 200 并给出取消马歇尔错误。
我的客户端代码如下所示：
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，因为它太长了，并且具有不同的字符。响应如下所示：
当我调试错误时，我注意到一半的响应不可见。错误声明：
响应模型：
type Response struct {
Tax Tax `json:"tax"`
Cur string `json:"cur"`
Rack []Rack `json:"rack"`
Gno string `json:"gno"`
}
type Tax struct {
Ver string `json:"ver"`
}
type TaxOfTur struct {
Name string `json:"name"`
}
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？
