将Chrome高级休息客户端请求转换为AFNetworking 2请求

Question

需要帮助，我试图上传文件到安全的API，我能够使用高级REST客户端chrome扩展成功上传，但是当我尝试将其转换为一个afnetworking post请求，它总是返回一个请求超时错误，我已经这样做了3天，但我总是收到请求超时错误，试图延长超时间隔但无济于事。

我的代码：

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; 

[[CookieHandler sharedManager] cookieEaterUsingCookiesInURL:OC_BASE_URL]; 
NSString *csrftoken = [[CookieHandler sharedManager] getCSRFToken]; 

[manager.requestSerializer setValue:csrftoken forHTTPHeaderField:COOKIES_CSRFTOKEN_KEY]; 
[manager.requestSerializer setTimeoutInterval:120]; 

AFHTTPRequestOperation *operation = [manager POST:[self composeFullUrlWithRestApi:uploadUrl] parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { 
    [formData appendPartWithFileData:fileData name:@"fileUpload" fileName:documentName mimeType:mimeType]; 
} success:^(AFHTTPRequestOperation *operation, id responseObject) { 
    NSLog(@"Success: %@", responseObject); 
} failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
    NSLog(@"Error: %@", error); 
}]; 

[operation setUploadProgressBlock:^(NSUInteger bytesWritten, NSInteger totalBytesWritten, NSInteger totalBytesExpectedToWrite) { 
    NSLog(@"Wrote %ld/%ld", (long)totalBytesWritten, (long)totalBytesExpectedToWrite); 
}]; 

打印operation变量得出：

<AFHTTPRequestOperation: 0x15731040, state: isExecuting, cancelled: NO request: <NSMutableURLRequest: 0x15523180> { URL: https://preprod.myUrl.com/uploadApi, headers: { 
    "Accept-Language" = "en;q=1"; 
    CSRFToken = "cfbaf91f-6f2b-4ed1-a094-06c8eec6f757"; 
    "Content-Length" = 32943; 
    "Content-Type" = "multipart/form-data; boundary=Boundary+B7082B5EB6A9063A"; 
    "User-Agent" = "ObjectiveConnect/5 (iPhone; iOS 8.0.2; Scale/2.00)"; 
} }, response: (null)> 

打印的错误率：

Error Domain=NSURLErrorDomain Code=-1001 "The request timed out." 
UserInfo=0x1561fec0 {NSErrorFailingURLStringKey=https://preprod.myUrl.com/uploadApi, 
NSErrorFailingURLKey=https://preprod.myUrl.com/uploadApi, 
NSLocalizedDescription=The request timed out., NSUnderlyingError=0x1567c400 "The request timed out."}

我应该提到这可能是一个服务器缺乏支持 AFNetworking请求或请求不能与所有服务器一起使用。

因此，基于这种想法，我又做手工创建的请求，所幸还提供了关于该职位的答案，所以这是我的版本：

typedef void (^uploadFileCompletionBlock)(NSURLResponse *response, id responseObject, NSError *error); 
- (NSMutableURLRequest *)buildRequestWithUrl:(NSString *)url 
           withFileData:(NSData *)paramData 
            fileName:(NSString *)name 
          fileContentType:(NSString *)fileContentType 
{ 
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; 
    [request setURL:[NSURL URLWithString:[self composeFullUrlWithRestApi:url]]]; 
    [request setHTTPMethod:@"POST"]; 

    [[CookieHandler sharedManager] cookieEaterUsingCookiesInURL:OC_BASE_URL]; 

    NSString *csrftoken = [[CookieHandler sharedManager] getCSRFToken]; 

    [request setValue:csrftoken forHTTPHeaderField:COOKIES_CSRFTOKEN_KEY]; 

    NSString *boundary = @"0xKhTmLbOuNdArY"; 
    NSString *endBoundary = [NSString stringWithFormat:@"\r\n--%@--", boundary]; 

    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary]; 
    [request addValue:contentType forHTTPHeaderField: @"Content-Type"]; 

    [request setValue:@"*/*" forHTTPHeaderField:@"Accept"]; 
    NSMutableData *tempPostData = [NSMutableData data]; 
    [tempPostData appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 

    // Sample file to send as data 
    [tempPostData appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"file\"; filename=\"%@\"\r\n", name] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [tempPostData appendData:[[NSString stringWithFormat:@"Content-Type: %@\r\n\r\n", fileContentType] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [tempPostData appendData:paramData]; 
    [tempPostData appendData:[endBoundary dataUsingEncoding:NSUTF8StringEncoding]]; 
    [request setHTTPBody:tempPostData]; 

    return request; 
} 

- (void) uploadFileWithFileData:(NSData *)fileData 
       andDocumentName:(NSString *)documentName 
       fileContentType:(NSString *)mimeType 
         uploadUrl:(NSString *)uploadUrl 
      andCompletionBlock:(uploadFileCompletionBlock)completionBlock 
{ 
    NSMutableURLRequest* request = [self buildRequestWithUrl:uploadUrl withFileData:fileData fileName:documentName fileContentType:mimeType]; 

    [NSURLConnection sendAsynchronousRequest:request queue:[[AFHTTPRequestOperationManager manager] operationQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) { 
     completionBlock(response, data, connectionError); 
    }]; 
} 

TL; DR

如果您的AFNetworking请求失败，请执行手动请求构造方式，您需要了解一些有关请求标头的信息以了解此内容。
