Http post请求在postman中可以正常工作，但在iOS中不行？

我正在使用RestKit发出网络请求。我用的是basic auth。我正在给服务器打电话。这给了我一个错误。但我接受了相同的请求主体和标题，并在postman中尝试了相同的请求，它运行良好

swift编码

  let requestMapping: RKObjectMapping = self.defineSyncUserProfileRequestMapping().inverseMapping()
        objectManager.addRequestDescriptor(RKRequestDescriptor(mapping: requestMapping, objectClass: UserProfile.self, rootKeyPath: nil, method: RKRequestMethod.POST))

        let responseMapping = self.defineSyncUserProfileResponseMapping() as RKDynamicMapping

        let responseDesriptor = RKResponseDescriptor(mapping: responseMapping, method: RKRequestMethod.POST, pathPattern: HabitsConstants.WebServicePath.POST_USER_PROFILE, keyPath: "", statusCodes: RKStatusCodeIndexSetForClass(UInt(RKStatusCodeClassSuccessful)))

        objectManager.addResponseDescriptor(responseDesriptor)

        objectManager.requestSerializationMIMEType = RKMIMETypeJSON
        self.objectManager.HTTPClient .setAuthorizationHeaderWithUsername(self.userCredential.username, password: self.userCredential.password)
        self.objectManager.HTTPClient.setDefaultHeader("Content-type" , value: RKMIMETypeJSON)
        RKMIMETypeSerialization.registerClass(RKNSJSONSerialization.self, forMIMEType: "text/json")


        objectManager.postObject(userProfile, path: URL, parameters: nil,
                                 success:{ operation, mappingResult in
                                    let response: NSArray = mappingResult.array()
                                    if response.count > 0 {
                                        if (response.objectAtIndex(0) .isKindOfClass(Error)) {
                                            let error: Error = response.objectAtIndex(0) as! Error
                                            NSLog("ERROR \(error.errorReason)");
                                            self.delegate?.handleMessage(MessageType.ERROR, data: 1.0,errorMessage: error.errorReason)
                                        } else if (response.objectAtIndex(0) .isKindOfClass(UserCredentialResponse)) {
                                            NSLog("Saved profile for user\(userProfile.userId)");
                                            self.getUserProfile()
                                            self.getUserTargets()
                                        }
                                    }

            },
                                 failure:{ operation, error in
                                    NSLog("Error: \(error!.localizedDescription)")
                                    self.delegate?.handleMessage(MessageType.UNKOWN_ERROR, data: 1.0,errorMessage: "")
            }
        )

我也有类似的问题。来自Swift的请求主体与Postman请求完全相同，我从Django Rest框架API主机得到了错误的请求响应

Postman将

Content-Type

标题添加为值

application/json

，如果这是您指定的主体类型。我试着在我的Swift iOS请求客户端（参见FMI）中自己设置它，现在我得到了成功的响应

我使用的相关代码片段：

var-request=URLRequest（url:renderedUrl）
request.setValue（“application/json；charset=utf-8”，forHTTPHeaderField:“内容类型”）
request.setValue（“application/json；charset=utf-8”，forHTTPHeaderField:“Accept”）

您可能需要在Swift中显示您的代码，并且可能需要在POSTMan中显示“那个”。我们不能在看不到代码的情况下猜出哪里出了问题。@Larme我在swift中添加了代码，postmanI建议使用Charles Proxy检查您发送的确切内容。从您的代码中，我看到您为

text/json

注册了serialiser，但没有注册

application/json

。你确定这是对的吗？
