在iOS中使用Documentum REST服务的文件（pdf，doc，xls）目标C

Question

我正在使用iOS应用程序，并且正在使用Documentum REST服务。直到现在，所有“GET”服务部分都正常工作，所有数据都正确地从服务器响应。但现在我需要做一些“POST”部分来将文档文件上传到服务器。

但我陷入从服务器错误。

所以下面的代码我正在使用上传文档文件到服务器，还提供详细的错误信息。

代码：

(IBAction)btnPostDocumentToServer:(id)sender { 
    NSString *filePath=[[NSBundle mainBundle] pathForResource:@"demotpcode" ofType:@"pdf"]; 
    NSData *pdfData = [NSData dataWithContentsOfFile:filePath]; 
    [self postMultipart:@"http://devser1:9090/dctm-rest/repositories/Mobile/folders/0b03445d800bfa1f" fileName:@"temCodeiOS" file:pdfData progress:nil params:nil]; 
} 

(void)postMultipart: (NSString*) url fileName: (NSString*)name file:(NSData*) fileData progress:(UIProgressView*) progressView params:(NSDictionary*) parametersDictionary { 
    NSDictionary *meta = @{@"properties":@{@"r_object_type": @"ecr_attachment", @"document_id": @"0903445d80210726",@"object_name": @"temCodeiOS.pdf",@"a_content_type":@"pdf",@"subject":@"new Doc from iOS Device"}}; //@{@"propreties": @{@"object_name": name}}; // You can modify this part to add more detail.  
    AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; 
    manager.requestSerializer = [AFJSONRequestSerializer serializer]; 
    [manager.requestSerializer setAuthorizationHeaderFieldWithUsername:[[NSUserDefaults standardUserDefaults] stringForKey:@"username"] password:[[NSUserDefaults standardUserDefaults] stringForKey:@"password"]]; 

    NSMutableURLRequest *request=[manager.requestSerializer multipartFormRequestWithMethod:@"POST" URLString:url parameters:parametersDictionary constructingBodyWithBlock:^(id<AFMultipartFormData> formData){ 
     [formData appendPartWithFileData:metaData name:@"metaData" fileName:@"metaData" mimeType:@"application/json"]; 
     [formData appendPartWithFileData:fileData name:@"binary" fileName:name mimeType:@"text/plain"]; 
    } error:nil]; 

    NSURLSessionUploadTask *uploadTask; // Create resumable task 
    uploadTask = [manager uploadTaskWithStreamedRequest:request progress:^(NSProgress * _Nonnull uploadProgress) { 
     dispatch_async(dispatch_get_main_queue(), ^{ 
      [progressView setProgress:uploadProgress.fractionCompleted]; //Update the progress view 
     }); 
    } 
    completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) { 
     if (error) { 
      NSLog(@"Error: %@", error); 
     } else { 
      NSLog(@"%@ %@", response, responseObject); 
     } 
    }]; 

    [uploadTask resume]; 
} 

详细ERROR：

Error: Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: bad request (400)" UserInfo={NSUnderlyingError=0x600000056350 {Error Domain=com.alamofire.error.serialization.response Code=-1016 "Request failed: unacceptable content-type: application/vnd.emc.documentum+json" UserInfo={com.alamofire.serialization.response.error.response= { URL: http://devser1:9090/dctm-rest/repositories/Mobile/folders/0b03445d800bfa1f } { status code: 400, headers { Connection = close; "Content-Type" = "application/vnd.emc.documentum+json;charset=UTF-8"; Date = "Thu, 15 Dec 2016 06:46:20 GMT"; Server = "Apache-Coyote/1.1"; "Transfer-Encoding" = Identity; } }, NSErrorFailingURLKey= http://devser1:9090/dctm-rest/repositories/Mobile/folders/0b03445d800bfa1f , com.alamofire.serialization.response.error.data=<7b227374 61747573……>, NSLocalizedDescription=Request failed: bad request (400)}

我使用Xcode 8.1，iOS 10.1 Simulator和AFNETWorking 3.0。请帮助我理解这一点并引导我，因为我第一次使用AFNETWorking。提前致谢。

调用的Documentum REST服务时，您正在使用错误的Content-Type值为：

"Request failed: unacceptable content-type: application/vnd.emc.documentum+json" 

我没有使用Documentum的REST除了Documetnum xCP的2.X，但在所有情况下application/json是正确的内容 - 类型（我不是说它会工作，只是看看你的服务期待什么）。
