第一个错误

我使用此代码，但我不知道如何在 iOS 中使用 api Mailjet？将 API 密钥放在哪里私有，公共等...我检查了github mailjet，关于 API 的文档mailJet 没有成功。

NSData *data = [NSData dataWithContentsOfFile:filePath];

NSLog(@"File Size: %lu",(unsigned long)[data length]);

//set up request
NSMutableURLRequest *request= [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:@"https://api.mailjet.com/v3/send"]];
[request setHTTPMethod:@"POST"];

//required xtra info
NSString *boundary = @"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];

//body of the post
NSMutableData *postbody = [NSMutableData data];
[postbody appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"thefile\"; filename=\"recording\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[@"Content-Type: application/octet-stream\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:data];
[postbody appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];

[request setHTTPBody:postbody];
NSURLConnection *apiConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

我通过“手动”发送进行测试，但我的答案很糟糕。我必须把 API KEY 和 SECRET KEY 放在哪里？在此处输入图像描述

我在 Mailjet 领导 API。

您的帖子中需要注意的几点：

  • 您的电话似乎缺少基本身份验证，有关设置它的更多详细信息，请参阅Postman 文档。您可以在此处获取您的 API 凭据
  • 您使用一段form-data Content-Type时间我们的 API 仅支持application/json作为输入格式。请参阅我们的API 指南，了解有关发送给我们的有效负载的更多详细信息
  • 您似乎没有在您提供的 Objective-C 代码中提供您的 API 凭据。与第一点相同，您可以从此处获取它们

我们不正式支持带有 Objective-C 或 Swift 的 iOS，对于给您带来的不便，我们深表歉意。

希望能帮助到你

感谢您选择 Mailjet 为您的电子邮件提供动力！
