org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Unexpected character (- (code 45)) in numeric value 问题分析 请求已经到了服务端在进行接口参数解析的时候报错未进入Controller就报错了排查后发现这个接口是使用formdata上传文件并携带了其他的参数前端请求接口的时候应该设置请求头的Content-type: multipart/form-data前端使用
const formData new FormData();
formData.append(file, param.file);
formData.append(fileModuleType, 1);
对象将文件与对应的数据参数一并的传给后端服务接口思路上没有问题但是数据到具体的服务时为什么解析不了了呢应该是数据经过转发后发生了变化。开始排查nginx配置。
location /cbdacim-auxiliary-library-ms-dev {proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_set_header X-Forwarded-Host $host;proxy_set_header X-Forwarded-Server $host;proxy_set_header Host $host;proxy_set_header accept-encodeing gzip, deflate;proxy_set_header content-type application/json;proxy_set_header X-Real-IP $remote_addr;proxy_set_header authorization $http_authorization;proxy_set_header accept */*;proxy_set_header x-bce-date $http_x_bce_date;proxy_connect_timeout 300;proxy_send_timeout 300;proxy_read_timeout 300;client_max_body_size 300m;proxy_pass http://gatewayservers; }其中 proxy_set_header content-type application/json;配置会将转发的请求重新设置content-type而在传输文件时需要设置content-type为multipart/form-data从而后端服务无法解析传过来的参数数据。至此问题原因找到。解决如下。
